QuickTime Player is a free multimedia player that allows users to view various file formats including video, audio, images and VR movies. This chapter provides instructions on basic QuickTime Player functions such as opening and playing files, controlling playback, changing settings and navigating movies. It also discusses playing copy-protected movies, viewing movie information, looping movies and using frame numbers/timecodes to navigate. The chapter explains how to open movies from the internet or that were recently used and view movies in full screen.
![Chapter 1 Using QuickTime Player 17
Opening Recently Used Files
You can easily open recently used files.
To open recently used files:
m Choose File > Open Recent > [option]
To change the number of items that appear in the Open Recent submenu (in
Mac OS X), choose QuickTime Player > Preferences, click General, and choose an option
from the Number of Recent Items pop-up menu. In Windows, choose Edit >
Preferences > Player Preferences.
Finding Movies Quickly Using QuickTime Favorites
You can easily find and open movies by putting pointers to them in your QuickTime
Favorites window. To view your list of favorites, choose Window > Favorites > Show
Favorites.
To add a movie to the Favorites list:
1 Open the movie in QuickTime Player.
2 Choose Window > Favorites > Add Movie As Favorite.
You can also drag a file to the Favorites list window.
To rearrange movies in the list, drag them. To delete an item from the list, drag the item
to the Trash or select the item and press the Delete key. (In Windows, drag the item to
the Recycle Bin or select the item and press the Backspace key.) Deleting an item from
the Favorites list does not delete the file from your hard disk (or wherever the file is
saved).
Playing Copy-Protected Movies
QuickTime movies can be encrypted so that only authorized viewers can watch them.
Such movies are known as“secured media files.”To use such a file, you must enter a
“media key,”which is usually available from the media file provider.
To enter a media key (in Mac OS X):
1 Open System Preferences, click QuickTime, and click Advanced.
2 Click Media Keys.
3 Click the Add button and then enter the key provided by the author or vendor.
To enter a media key (in Windows):
1 Choose Edit > Preferences > QuickTime Preferences.
2 Click Advanced.
3 Click Media Keys.
4 Click Add and then enter the key provided by the author or vendor.](https://image.slidesharecdn.com/quicktime7userguide-101023233627-phpapp02/85/Quick-time7-user_guide-17-320.jpg)
![20 Chapter 1 Using QuickTime Player
You can also set options for all movies playing at full screen. For example, you can hide
the movie controls or change the amount of time they’re displayed before being
hidden. To set these options in Mac OS X, choose QuickTime Player > Preferences and
click Full Screen. To set these options in Windows, choose Edit > Preferences >
Player Preferences, and then click Full Screen.
Note: As long as“Display full-screen controls”is selected in QuickTime Player
Preferences, you can make hidden controls appear by moving the pointer.
Changing Movie Size for Playback
QuickTime Player includes several options for changing movie playback size.
To change a movie’s playback size, choose View > [a size], or drag the resize control in
the lower-right corner of the window. To stretch the movie in any direction, hold down
the Shift key when you drag (holding down the Shift key while dragging doesn’t
preserve the aspect ratio).
To return the movie to its default size and aspect ratio, press Command-1 (in Windows,
press Alt-1).
You can also view movies at full screen, with additional sizing options available during
full-screen playback. For more information, see “Viewing Movies at Full Screen”on
page 19.
Looping a Movie
You can play a movie repeatedly. When the movie finishes, it automatically starts
playing again.
To loop a movie:
m Choose View > Loop.
With QuickTime Pro, you can also play the movie forward and then backward
repeatedly by choosing View > Loop Back and Forth.
Simultaneously Playing Multiple Movies
You can have more than one QuickTime Player window open at a time.
To open more than one QuickTime Player window, do one of the following:
 Double-click another movie file.
 Choose View > Play All Movies.
By default, when you have more than one QuickTime Player window open, the audio
plays only on the active (frontmost) QuickTime Player window. For information about
changing this setting, see “Changing Playback Preferences”on page 18.](https://image.slidesharecdn.com/quicktime7userguide-101023233627-phpapp02/85/Quick-time7-user_guide-20-320.jpg)
![40 Chapter 3 Editing and Authoring with QuickTime Pro
3 Choose File > Export. In the Export pop-up menu, choose “Text to Text.” In the Use
pop-up menu, choose“Text with Descriptors.”
4 Click Options. In the Text Export Settings dialog, select“Show Text, Descriptors, and
Time”; select“Show time relative to start of Movie”; and set fractions of seconds to 1/30
(the default is 1/1000).
5 Click OK, then click Save to create a text file with descriptors.
6 Open the exported list in your text editor or word processor, and open the target
movie in QuickTime Player.
7 Choose Window > Show Movie Info.
8 In QuickTime Player, drag the playhead on the timeline to find the first point in the
movie where you want to begin a new chapter.
Use the Right and Left Arrow keys to step forward or backward a frame at a time as
needed. Note the current time in the Properties window.
9 In the text file, find the first chapter title and change the timestamp just before that
chapter title to the time you noted in the Properties window.
The timestamp might now read, for example, [00:01:30.15], meaning that selecting the
first chapter title will jump the viewer 1 minute, 30 seconds, and 15 frames into the
movie.
10 Repeat steps 9 through 11 until you’ve identified all the places in the movie that
correspond to the chapter divisions and you’ve entered the proper timestamps in the
text file.
11 Change the last timestamp (the one after the last chapter title in the text file) to match
the duration of the movie.
12 Save the text file and import it into QuickTime Player.
QuickTime creates a new movie with just a text track.
13 Choose Edit > Select All, choose Edit > Copy, and close the movie.
14 Click in the main movie, choose Edit > Select All, and then choose Edit >“Add to
Movie.”
QuickTime adds the text track to the movie.
15 Choose Window > Show Movie Properties.
16 In the Properties window, select the video or audio track you want to associate with
the chapter track, and click Other Settings.
17 Choose the main video or audio track from the Chapters pop-up menu.
If you have a movie with alternate subtitle or sound tracks, you can create multiple
chapter lists in different languages and set the appropriate subtitle or sound track as
the owner of each chapter list. The chapter list will change to match the selected
language.](https://image.slidesharecdn.com/quicktime7userguide-101023233627-phpapp02/85/Quick-time7-user_guide-40-320.jpg)

- 11. 1 11 1 Using QuickTime Player This chapter explains the basics of using QuickTime Player. Opening and Playing Files You can open and play QuickTime movies in QuickTime Player or in your web browser. Opening and Playing Movies in QuickTime Player You can use QuickTime Player to play media stored on your computer’s hard disk, a CD, a DVD, or the Internet. To open a movie on your hard disk, a CD, or a DVD, do one of the following: Â In the Finder (or Windows Explorer), double-click the file or drag it to the QuickTime Player application icon. Â Choose File > Open and select the file. Â Drag the file to the QuickTime Player icon in the Dock (Mac OS X only). To open a movie on the Internet, open QuickTime Player, choose File > Open URL, and enter the URL (the Internet address) for the movie file. When audio is detected, you’ll see activity in the equalizer. Playhead Volume Play/Pause Fast-forward; go to endGo to beginning; rewind Drag to resize the window.
- 12. 12 Chapter 1 Using QuickTime Player QuickTime Player has onscreen controls similar to those found on CD players and DVD players. Use the controls to play, pause, rewind, fast-forward, jump to the beginning or end, and adjust the volume of a QuickTime movie. You can also use the controls to move forward or backward in a movie. To go to a specific point in the movie, drag the playhead (the small black triangle) in the timeline. To step through frame-by-frame, first click the small black triangle and then press the Right or Left Arrow keys on your keyboard. Some movies have chapter lists you can use to jump to a specific point in a movie. If a movie has a chapter list, a pop-up menu appears between the timeline and the equalizer. You can drag the handle in the lower-right corner of the window to resize the viewing space. Opening and Playing Files in a Web Browser With the QuickTime plug-in (part of the free QuickTime software), you can play most multimedia you encounter on the Internet within your web browser. On some websites, movies play automatically. On other sites, you need to click an image of the movie or a play button. When a movie plays on a webpage, you typically see controls you can use to play, pause, fast-forward, rewind, and adjust the volume of the movie. To play a movie in a web browser, go to the website and follow the site’s instructions to watch the movie. Choose a chapter from the pop-up menu to jump to that chapter. Volume Play/Pause Rewind; fast-forward QuickTime Pro menu The playhead
- 13. Chapter 1 Using QuickTime Player 13 With QuickTime Pro, you also have the option of saving the movie to your hard disk (if the author of the movie allows it). To save a movie from the web, click the downward- pointing arrow on the right and choose“Save as QuickTime Movie”or“Save as Source” from the QuickTime Pro menu. If the movie is a Real-Time Streaming Protocol (RTSP) movie, it is saved as a small“reference movie”that points to the actual movie on the Internet. The QuickTime website has a number of QuickTime movies (including the latest movie trailers) that you can view in your web browser. Go to www.apple.com/quicktime. Adjusting Playback Preferences for Internet Movies When you watch movies on the Internet, they start playing automatically. You can, however, download entire movies to your hard disk before they start playing so that you can watch the movies at your convenience. To download movies before they start playing (in Mac OS X): 1 Choose QuickTime Player > QuickTime Preferences and click Browser. 2 Deselect“Play movies automatically.” To download movies before they start playing (in Windows): 1 Choose Edit > Preferences > QuickTime Preferences. 2 Choose Browser. 3 Deselect“Play movies automatically.” So that you don’t have to download movies and images each time you view them on a website, QuickTime can save these files in a storage area called a cache. If you view a movie or image more than once, having the item cached improves performance. To have QuickTime cache movies and images you view on the Internet, select “Save movies in disk cache.”You might not want to select this option if you don't have sufficient free space on your hard disk to allocate a cache, or if, for security reasons, you don't want movie data stored in a cache file. You can specify how big to make the cache by changing the Movie Cache Size setting. How big you make the cache depends on how much free space your hard disk has. A larger cache can hold more files (or larger files), but it takes up more space on your hard disk. After the QuickTime cache fills all the space reserved for it, older items are automatically deleted from the cache when new items are added. To clear the cache, click Empty Download Cache (in Windows, choose Download Cache in QuickTime Settings and then click Empty Cache Now). You might want to clear the cache for security or privacy reasons, or to recover free space on your hard disk.
- 14. 14 Chapter 1 Using QuickTime Player QuickTime automatically detects your Internet connection speed so that you get the highest-quality QuickTime content that your Internet connection can support. If movies you’re watching on the Internet don’t play properly, however, it may help to change the connection speed setting. To change the connection speed setting in Mac OS X, open QuickTime Preferences and click Streaming. In Windows, open QuickTime Preferences and choose Connection Speed. QuickTime tries to play versions of the movie authored to match the connection speed you choose. If you choose a speed slower than your actual connection speed, the resulting movie may be smaller in size and lower in quality than your connection can actually support. If you choose a speed faster than your actual connection, QuickTime playback may stutter or appear jerky because it is sending more data than your connection can support. If you’re unsure of your connection speed, check with your Internet service provider (ISP). If you change your connection speed setting and later want to make QuickTime automatically detect your speed again, choose Automatic from the Streaming Speed pop-up menu (in Mac OS X). To set the Internet connection speed in Windows, choose Edit > Preferences > QuickTime Preferences, and then follow the directions above. Instant-On QuickTime includes Instant-On, a technology that dramatically reduces buffer (wait) time when you view streamed video. Instant-On provides an instantaneous viewing experience; you can navigate quickly through video as if it were on your hard disk. To experience Instant-On, you must have a broadband connection. The responsiveness of Instant-On is affected by available bandwidth and the size, or data rate, of the content. It can also be affected by the codec used to compress the streaming video. Instant-On is on by default. If you experience problems with streamed video, you can change the wait time (drag the Play slider) or turn off Instant-On (open QuickTime Preferences and click Streaming). Viewing Streamed Files Behind a Firewall QuickTime streaming chooses the best protocol (a method of communicating via the Internet) for your needs. Typically, QuickTime streaming uses Real-Time Streaming Protocol (RTSP) to ensure the best performance. If your network connection is protected by a firewall, you may want to use the HTTP protocol instead.
- 15. Chapter 1 Using QuickTime Player 15 To use HTTP streaming (in Mac OS X): 1 In QuickTime Player, choose QuickTime Player > QuickTime Preferences (or open System Preferences and click QuickTime). 2 Click Advanced. 3 Choose Custom from the Transport Setup pop-up menu. 4 Choose HTTP from the Transport Protocol pop-up menu. To use HTTP streaming (in Windows): 1 In QuickTime Player, choose Edit > Preferences > QuickTime Preferences. 2 Choose Advanced. 3 Choose Custom from the Transport Setup pop-up menu. 4 Choose HTTP from the Transport Protocol pop-up menu. If QuickTime can configure itself for your firewall, you can now watch streaming QuickTime movies. If you still experience problems, contact your network administrator or see the information on the Apple QuickTime website (www.apple.com/quicktime). Setting QuickTime to Handle More or Fewer File Types (MIME Settings) When files are downloaded over the Internet, each file is assigned a MIME type to indicate what kind of file it is. Your browser keeps track of which plug-in should be used to display each kind of file. QuickTime can display a wide variety of file types. To make QuickTime handle more or fewer file types, you can edit the MIME type settings. If you edit the list, you can return to the default list by following the instructions below and clicking Use Defaults. To edit MIME settings in Mac OS X, open QuickTime Preferences and click Advanced. In Windows, choose Edit > Preferences > QuickTime Preferences, choose Browser, and click MIME Settings. Viewing QuickTime Virtual Reality (QTVR) Movies QTVR movies display three-dimensional places (panoramas) and objects with which the user can interact. With a QTVR panorama, it’s as if you’re standing in the scene and you can look around you up to 360 degrees in any direction. In a QTVR movie of an object, you can rotate the object in any direction. To pan through a QTVR movie, drag the cursor through the scene. To zoom in or out, click the + or – button. (If the buttons are not showing, zoom in by pressing Shift; zoom out by pressing Control.)
- 16. 16 Chapter 1 Using QuickTime Player Some QTVR movies have hot spots that take you from one scene (or node) to another. As you move the mouse over a hot spot, the cursor changes to an arrow. To see all the places where you can jump from one node in a scene to another, click the Show Hot Spot button (an arrow with a question mark in it). A translucent blue outline of any hot spots within the currently visible VR scene appears. (If there are no hot spots, clicking this button has no effect.) Click a hot spot to jump to a new scene.

To adjust memory options for a track: 1 Choose Window > Show Movie Properties. 2 Select the track you want to adjust and click Other Settings. 3 To put the track into memory, select“Preload this track.” 4 To keep track data in memory, select Cache. Use these options only with tracks that contain very small amounts of data; too much data in memory may cause poor performance, system errors, or unpredictable results. Creating Movies and Other Media With QuickTime Pro, you can create movies in various ways. Recording Video and Audio With a video camera and a Macintosh computer you can use QuickTime Pro to record a movie. QuickTime Pro can capture video from most FireWire-equipped sources, including the Apple iSight, DV cameras, and some webcams. With a Macintosh or Windows computer, you can also record audio using a built-in or external microphone. To record audio or video with QuickTime Pro: 1 Connect the camera or microphone to the computer (unless you are using a built-in microphone). 2 In QuickTime Pro, choose File > New Movie Recording (or File > New Audio Recording). A preview window appears, which you can use to adjust settings such as camera position, lighting, and audio level before you start recording. 3 To start recording, click the Record button at the bottom of the window. 4 To stop recording, click the button again. The movie you just recorded appears in a QuickTime movie window. By default, the movie is saved on the desktop, but you can choose a different default location in the Recording pane of QuickTime Player Preferences. To see where the movie has been saved, Command-click the icon at the top of the window.
- 26. 26 Chapter 2 Getting Started with QuickTime Pro Setting Recording Options When you first use QuickTime Pro to record video or audio, settings are automatically chosen for you. If you want, you can change settings such as which recording device and format to use, and where recorded movies are stored. To change recording options: 1 Choose QuickTime Player > Preferences. 2 Click Recording (or Audio Recording in Windows). 3 Choose the desired options for your video source, microphone, and quality, and then choose a default location to store recorded files. About Saving Movies With QuickTime Pro, you can create and edit movies, and then save them. When you choose File > Save As, you can save the movie as one of the following: Â A self-contained movie includes all the data (video, audio, and so on) you used to create the movie within a single file. Â A reference movie contains pointers to other movies (or parts of movies) stored elsewhere, such as in different folders on your hard disk or even on a web server. Pointers to other movies are created when, for example, you copy and paste part of a movie from one movie into another. If you are concerned about free space on your hard disk and can be sure your source movies won’t change location, you can save your movie as a reference movie; the media you copy and paste is stored as a space-saving pointer to that media, rather than being stored entirely inside your new movie file. When you play a reference movie, QuickTime follows the pointers to access and play the other movies (or parts of movies). To determine whether a movie contains pointers to other data, choose Window > Show Movie Properties, select the movie at the top of the window, and click Resources. If the file containing the movie does not appear in the list, then the movie has pointers and is not self-contained. In Mac OS X, you can Command-click the icon to see the name and location of the file that contains the movie. The term“reference movie”is also used for the files you can create to intelligently deliver different-sized streams to different users depending on their connection speeds. For more information, see “Creating Reference Movies to Optimize Web Playback”on page 48.
- 27. Chapter 2 Getting Started with QuickTime Pro 27 Saving Movies from the Internet With QuickTime Pro, you can save (download) a movie viewed in your web browser to your hard disk. (The movie must be authored to allow for saving.) If it’s a streaming movie, QuickTime Pro saves a small“reference movie”that points to the stream. To save an Internet movie on your hard disk: 1 When the movie finishes loading (when the entire progress bar is filled with gray), click the down arrow in the playback controls. 2 Choose“Save as QuickTime Movie.” If this command is not available, the movie is authored so that it cannot be saved. Creating a Slideshow or Animation from Still Images With QuickTime Pro, you can combine a series of still images to create a movie that plays like a slideshow. This process is an easy way to share the pictures from your digital camera or mobile phone. Note: Slideshows look best when all the images are the same size. To create a slideshow from still images: 1 Put all the graphic files you want to include in a folder. 2 Name each file with the same name followed by an increasing number; for example, “picture1,”“picture2.” Most digital cameras number files automatically. The numbers must be increasing but don’t have to be precisely sequential (for example, you could name the files“picture1,” “picture5,”“picture10,”and so on). 3 In QuickTime Player, choose File > Open Image Sequence, and then select the first file. 4 Choose a frame rate (the number of frames displayed per second) from the Frame Rate pop-up menu. Slideshows usually work best when slides are shown at 2 to 3 seconds per frame. QuickTime Pro creates the movie, which shows each picture in sequence. 5 Choose File > Save to name and save the movie.
- 28. 28 Chapter 2 Getting Started with QuickTime Pro You can add music to your slideshow by adding an audio track to your movie before saving it. Open an audio file, select the portion you want to add to the slideshow, and choose Edit > Copy. Select the slideshow (or a portion of it) and choose Edit > Select All, then choose Edit >“Add to Selection and Scale.”The audio is sped up or slowed down to fit the length of the paste destination (the pitch remains the same). For best results, make the slideshow length match that of the audio as closely as possible. You can also lengthen a soundtrack by adding multiple audio files to the movie, each beginning at a different point. Alternatively, you can keep the original audio speed and alter the image speed by opening a new player window, copying and pasting the audio into the new window, and then copying the slideshow and pasting it into the new window by choosing Edit >“Add to Selection and Scale.” If you’re using Mac OS X: You can also use the recording feature in QuickTime Pro to narrate your slideshow. See “Recording Video and Audio”on page 25. Creating a Still Image from a Movie With QuickTime Pro, you can export a single frame from a movie as an image file. To save a still image from a movie: 1 Move the playhead to the frame you want to export. 2 Choose File > Export. 3 Choose“Movie to Picture”from the Export pop-up menu. 4 Click Options and choose a format from the“Compression type”pop-up menu. To export every frame from the movie as a series of images, choose“Movie to Image Sequence.”Exporting every frame can generate a very large number of files; you may want to export to a folder rather than to the desktop. Converting Files into QuickTime Movies If you have QuickTime Pro, you can use QuickTime Player to convert many types of video, audio, graphics, and animation files (including Flash files) into QuickTime movies. To convert a file into a QuickTime movie, open it in QuickTime Player and then choose File > Save.

Simple Editing With QuickTime Pro, you can perform movie-editing tasks. Selecting and Playing Part of a Movie To perform editing functions such as Copy and Delete, in most cases you need to first select the desired portion of a movie. (If you don’t select anything, the edit commands work on the current frame.) To select a portion of a movie, move the In and Out selection markers. The darkened area between the two markers indicates the selected portion. To fine-tune the selection, select a marker and move it with the arrow keys. You can also move the playhead and press I (for In) or O (for Out) to set the start or end point of the selection, even while the movie is playing. To play the selection, choose View > Play Selection Only (so that the checkmark appears), then click Play. To play the whole movie, choose View > Play Selection again (to remove the checkmark). With QuickTime Pro, you can save the movie (choose File > Save) so that the next time it is opened, only the part you selected plays. Tip: To move the In or Out marker to a different position, drag the playhead to the desired position (or use the arrow keys), then press I or O.In and Out markers, showing the selected portion of the movie The playhead
- 31. Chapter 3 Editing and Authoring with QuickTime Pro 31 Note: By default, the selection markers hide when nothing is selected, making it easy to determine whether or not a frame is selected. To turn off this option so that the selection markers appear even when nothing is selected, change the“Hide selection indicators for empty selection”option in QuickTime Player preferences. Cutting, Copying, or Deleting a Section of a Movie Selecting and moving, copying, or deleting (trimming) part of a movie is easy in QuickTime Pro. To cut, copy, or delete part of a movie: 1 Move the playhead until the desired frame appears, or select the part of the movie you want to modify (use the In and Out selection markers and the arrow keys). 2 Choose Edit > Copy, Cut, or Delete. If you choose Copy or Cut, you can paste the selection elsewhere. 3 Position the playhead where you want to paste the selection and choose Edit > Paste. QuickTime Pro inserts the selection you pasted at the position of the playhead. You can also delete all parts of a movie that are not selected by choosing Edit > “Trim to Selection.” Note: After you delete parts of a movie, the file size stays the same until you choose File > Save As and select“Save as a self-contained movie.” Combining Two QuickTime Movies into One With QuickTime Pro, you can easily add one movie to another to make one longer movie. To combine two movies: 1 In QuickTime Player, choose Edit > Select All to select the entire contents of the first movie. 2 Choose Edit > Copy, then open the second movie. 3 Move the playhead to the point at which you want to insert the movie (usually the very beginning or end of the original movie), and choose Edit > Paste. 4 Choose File > Save As to name and save the new movie.
- 32. 32 Chapter 3 Editing and Authoring with QuickTime Pro Working with Tracks A QuickTime movie is made up of one or more“tracks.”Each track stores a particular kind of data. For example, a QuickTime movie could have a video track, music tracks, and sound effects tracks. With QuickTime Pro, you can edit tracks individually. You can move tracks from one movie to another, turn a track on or off, delete tracks, or modify the information contained in a track. Turning Tracks On or Off With QuickTime Pro, you can choose one or more tracks to enable or disable. For example, you might want to turn off tracks to simplify editing, or to hide a track in a final movie. When you export a movie, only enabled tracks are exported. To turn movie tracks on or off: 1 In QuickTime Player, choose Window > Show Movie Properties. The movie’s tracks appear in the list at the top of the Properties window. 2 Use the Enable checkboxes to turn tracks on (selected) or off (deselected). To delete a track, drag it to the Trash, or select it and click Delete,.You can also choose Edit > Cut, or press the Delete key. Note: For audio tracks, other options are available by clicking Audio Settings. To play only the audio in the selected track, select Solo. To play the movie without audio, select Mute. Extracting, Adding, and Moving Tracks With QuickTime Pro, you can create a new movie from one or more tracks of an existing movie, while leaving the original movie file intact. For example, you could create a movie that uses only the audio from an existing movie. To do so, you extract the desired tracks. You can also add the extracted track to an existing movie. Audio narration Video 1 Video 2 Text title Text credits Audio sound effects
- 33. Chapter 3 Editing and Authoring with QuickTime Pro 33 To extract a track (and add it to another movie): 1 Choose Window > Show Movie Properties. 2 Select the desired track or tracks and click Extract. You can select more than one track by holding down the Shift key when you click. QuickTime creates a new movie containing the extracted tracks. 3 To add the extracted track to another movie, select the movie (or the portion of it you want your pasted media to fit into) and choose Edit >“Add to Movie.” When you add a track to a movie, the track’s duration is unaltered. For example, if you add a 10-second sound track to a 1-minute movie, the sound track plays for 10 seconds, starting at the position in the movie where you added the track. To“scale”a track so that it stretches or compresses to a particular length, drag the In and Out markers of the target movie to select the duration you want the new track to cover and then choose Edit >“Add to Selection and Scale”in step 3. Scaling audio may change the speed of the audio (although the pitch remains the same when you play the movie in QuickTime Player). You could add video to sound instead, and speed up or slow down the video to match the audio. You might have better results if you compare the timelines of the two tracks and cut from one or the other until they have the same duration. Working with Audio Tracks QuickTime audio includes music tracks, which contain MIDI or other data, and sound tracks, which contain digitized audio. Adding an Audio Track to a QuickTime Movie You can easily add audio and other tracks to a QuickTime movie. To add an audio track to a movie: 1 In QuickTime Player, choose File > Open File and select the audio file you want to import. 2 In the QuickTime Player window that opens, choose Edit > Select All to select the entire audio file, then choose Edit > Copy. 3 Open the movie to which you want to add the audio. 4 To add the audio to the whole movie, choose Edit > Add. To add the audio to a part of the movie, select a part and choose Edit >“Add to Selection and Scale”. “Add to Selection and Scale”slows down or speeds up the audio track to fit the length of the selected part of the movie; the pitch remains the same (when you play the movie in QuickTime Player). You could add video to sound instead, and speed up or slow down the video to match the audio. You might have better results if you compare the timelines of the two tracks and cut from one or the other until they have the same duration.
- 34. 34 Chapter 3 Editing and Authoring with QuickTime Pro Note: If your audio and video are created by the same device, such as a DV camera, and are created at the same time, the audio and video will be synchronized. Changing Sound Track Volume Levels and Other Audio Settings With QuickTime Pro, you can change the volume and balance of audio and music tracks. For example, if a movie has more than one audio track, you can adjust the volume of the tracks relative to one another. You can also change the bass and treble levels. To change settings for an audio track: 1 In QuickTime Player, choose Window > Show Movie Properties. 2 In the Properties window, select the audio track and click Audio Settings. 3 Drag the sliders to adjust the settings. 4 Use the pop-up menu to the right of each audio channel to specify where the channel’s sound should be directed.

- 35. Chapter 3 Editing and Authoring with QuickTime Pro 35 Pasting Graphics and Text into a Movie With QuickTime Pro, you can paste graphics and text into a QuickTime movie. If a pasted graphic is larger than the movie’s dimensions, QuickTime Pro resizes the movie to fit the dimensions of the graphic. For best results, size graphics (using a graphics program) to match the movie size before you insert them. You can export a single frame from the movie to use as a guide for text placement. (See “Creating a Still Image from a Movie”on page 28.) To find a movie’s dimensions, choose Window > Show Movie Properties, select the video track, and click Visual Settings. To add graphics or text: 1 Copy the text or graphic to the Clipboard. 2 In QuickTime Player, move the playhead to the point at which you want the copied item to appear. 3 Choose Edit > Paste. This procedure inserts the graphic into the movie at the Paste location, in its own frame. To paste the graphic onto the frame at the Paste location, choose Edit >”Add to Movie.” To make a graphic show up in more than one frame, select the portion of the movie you want to add it to and choose Edit >“Add to Selection and Scale.”You can use this technique to add a company logo throughout a movie. (Also see “Changing a Track’s Transparency”on page 39.) Working with Text Tracks You can add text to a QuickTime movie to create titles, credits, and subtitles. With QuickTime Pro, text tracks are searchable, so you can use keywords to find precise frames in the movie. The following topics provide details about adding text tracks. Adding a Text Track to a QuickTime Movie With QuickTime Pro, you can import a text file into a QuickTime movie. To add a text track: 1 Create a text file containing the text you want in the movie, and save the file as text only (.txt). Separate each paragraph with a return character. Each paragraph appears in a separate frame of the movie. By default, each text frame is displayed for 2 seconds. 2 In QuickTime Player, choose File > Open File and select the text file. 3 Click Open.

You can also insert tags throughout the text to change values while the movie plays. Setting the Frame Duration of a Text Track With QuickTime Pro, you can set the duration of each frame in an existing text track to a value other than 2 seconds. To do so, you export the track, make changes, then reimport the track. To change the current text frame information: 1 In QuickTime Player, choose File > Export and choose“Text to Text”from the Export pop-up menu. 2 Click Options and select“Show Text, Descriptors, and Time.” 3 Edit the information in the text file and then import the track back into the movie.
- 37. Chapter 3 Editing and Authoring with QuickTime Pro 37 The duration for each line of text in the text file appears on a separate line before the line of text. The time you type is the length of time after the movie has started at which this line of text will appear. Timestamps are specified as hours:minutes:seconds:fractions of a second (the default Text to Text export setting is 1/600th of a second). For example, if you enter the time 00:02:11:00, the text on the following line appears at 2 minutes and 11 seconds into the movie. For information about the other text track descriptors, see the developer section of the QuickTime website at www.apple.com/quicktime. Specifying Languages for Individual Tracks With QuickTime Pro, you can create a movie with support for multiple languages by specifying a language for an individual track. For example, you can create a movie that contains a separate audio track for each language. QuickTime automatically plays the correct track, based on the language setting of the user’s computer. To specify languages: 1 Create or assemble the alternate tracks. Record voiceovers in each desired language or create text tracks to use as subtitles. Save each alternate track as a self-contained movie, and put all the alternates together in a single folder. 2 Put a copy of your original movie, self-contained and minus any tracks that are now stored as alternates, in the folder with the alternates. 3 Open the movie and choose Window > Show Movie Properties. 4 In the Properties window, select a sound or text track and click Other Settings. 5 Choose the language of this track from the Language pop-up menu. 6 Choose a track to use when a different language is selected from the Alternate pop-up menu. 7 Save as a self-contained movie (choose Edit > Save As and make sure“Make movie self- contained”is selected). 8 Repeat these steps for additional language tracks; each time, choose the previously selected language from the Alternate pop-up menu.

- 42. 4 42 4 Exporting Files with QuickTime Pro If you want more control over how QuickTime creates a file, use the Export feature of QuickTime Pro. With QuickTime Pro, you can export a movie to a number of different file formats, such as QuickTime movie (MOV), MPEG-4, 3GPP, 3GPP2, AVI, and DV. In addition, you can export an audio track to several different audio formats, export the individual frames of a movie as separate image files, or export a text track to a text file. To see the list of file formats available for a movie open in QuickTime Player, choose File > Export and browse the list of file format choices in the Export pop-up menu. About Video and Audio Compression Because uncompressed video and audio require a lot of disk space to store and a lot of bandwidth (the rate at which data can be transferred) to deliver, you’ll want to compress (encode) your movie before sending it to another computer or on the web. Movies are usually compressed (encoded) as part of the export process.
- 43. Chapter 4 Exporting Files with QuickTime Pro 43 Exporting Files Using Presets QuickTime Pro offers a myriad of settings and options for compressing video and audio during export. To help simplify the process of compressing and exporting, QuickTime Pro also offers export presets. Different presets are available for each file format. To export a movie using presets: 1 In QuickTime Player, open the movie you wish to export. 2 Choose File > Export. 3 Choose a file format from the Export pop-up menu. 4 Choose the preset that best meets your needs from the Use pop-up menu. For example, to export a movie for use with a video-capable iPod, choose“Movie to iPod.”To export a movie that is optimized for Apple TV, choose“Movie to Apple TV.” You can also create movies for iPhone by choosing one of the“Movie to iPhone” options. 5 Choose a filename and location, and click Save. Note: To use the same settings you used during the last export, choose Most Recent Settings from the Use pop-up menu. Customizing Export Settings For the greatest possible control when compressing and exporting media files, use the export options available in QuickTime Pro. For video compression and export, QuickTime Pro offers customizable settings in three categories: video settings, filters (also known as special effects), and image size. QuickTime Pro also offers many options for customizing compression settings for sound. The following topics provide information about which options to choose when exporting and compressing movies. Customizing Video Export Settings To customize video settings for export: 1 Choose File > Export. 2 Choose a file format from the Export pop-up menu. For the options discussed below, choose“Movie to QuickTime Movie.” 3 Click Options.
- 44. 44 Chapter 4 Exporting Files with QuickTime Pro 4 In the Video area of the Movie Settings dialog, click Settings, and then choose your settings. Â Compression type: Choose the video compressor (codec) you want to use to compress your video. For the highest quality at the lowest data rate (or the smallest file), H.264 is recommended. Â Data rate (bit rate): In general, the higher the data rate, the better the quality, but the bigger the file. In most cases, you’ll want to set a data rate based on the way your movie will be viewed. For example, for streaming to Internet dialup connections, limit the data rate to around 45 kilobits per second to leave room for network traffic. If the file will be downloaded for playback, the data rate can be higher (a 56K modem user, however, has longer to wait before playback begins). The data rate of a movie is also affected by other compression options you set, such as the frame rate. To let the compressor choose an appropriate data rate, select Automatic. Â Optimized for: Choose your intended delivery method from the“Optimized for” pop-up menu. This setting informs the codec how much the data rate can vary above and below the data rate you choose. This option is available only for compressors that can apply limits, such as H.264. Â Key frame options: Many compressors use“frame differencing”to compress moving images. Frame differencing is the process of determining what information has changed from a starting frame (called a key frame) to subsequent frames. The key frame contains all of the information for an image. Subsequent frames contain only the information that has changed. Depending on the compressor you use, you can specify how often you want key frames to occur. If you don’t have enough key frames, the quality of your movie might be lower because most frames are generated from others. However, more key frames result in a larger movie with a higher data rate. With some compressors, an additional key frame is inserted automatically if too much of the image has changed from one frame to the next. A good rule of thumb for general use is to have one key frame every 5 seconds (multiply the frames per second by 5). If you are creating a file for RTSP streaming and have concerns about the reliability of the delivery network (as with the public Internet), you may want to increase key frame frequency to one key frame every 1 or 2 seconds. To let the compressor choose the key frame interval, select Automatic. Â Frame rate: Frame rate is the number of individual images shown every second. Standard (NTSC) video has a frame rate of 29.97 frames per second (fps), and the standard for film is 24 fps. The European standard (PAL) is 25 fps. QuickTime movies are sometimes created with a slower frame rate to reduce bandwidth and CPU requirements.
- 45. Chapter 4 Exporting Files with QuickTime Pro 45 Movies with higher frame rates show motion better but have larger file sizes. If you choose a frame rate that’s lower than the movie’s current frame rate, frames will be deleted. If you choose a number that’s higher than the movie’s current frame rate, existing frames will be duplicated (not recommended, since it increases file size without improving quality). When choosing a frame rate, use a simple fraction of your current frame rate, such as 1/2, 1/3, and so on. For example, if your current frame rate is 30 (29.97), use 15 or 10. Â Other options: Some compressors or codecs offer options specific to the codec. After you select a compressor (codec), any special options appear. Adding Special Effects and Filters to a QuickTime Movie With QuickTime Pro, you can add special effects such as blur, emboss, and film noise to a movie before you export it. You add special effects by using filters. To set a filter for a movie: 1 In QuickTime Player, choose File > Export. 2 Choose“Movie to QuickTime Movie”from the Export pop-up menu. 3 Click Options, click Filter, and select the filter and settings you want to use. The selected filter is applied to the entire movie. Changing Image (Frame) Size With QuickTime Pro, you can change the size of a movie’s video frame. For example, if your movie will be viewed on a small screen (such as a mobile device), you can change the movie’s dimensions to match the target device. You can experiment with making the frame size smaller for a given data rate to get better encoding results. To change the size of a movie’s video frame: 1 Choose File > Export. 2 Choose a file format from the Export pop-up menu. 3 Click Options. 4 In the Video area of the Movie Settings dialog, click Size and then choose an option: Â Use current size: This option (the default) keeps the exported movie’s image size the same as your original source movie. Â Use custom size: When you choose this option, you can specify (in pixels) a height and width for the exported movie’s image size. For best results, choose dimensions smaller than your source movie, and keep the height-to-width ratio the same as the source (so that objects don’t appear distorted).
- 46. 46 Chapter 4 Exporting Files with QuickTime Pro Customizing Sound Export Settings To customize sound settings for export: 1 Choose File > Export. 2 Choose“Movie to QuickTime Movie”from the Export pop-up menu. 3 Click Options. 4 In the Sound area of the Movie Settings dialog, click Settings and then choose your options: Â Format: Choose the compressor (codec) you want to use for compressing sound. For general use and Internet delivery of music, MPEG-4 Audio (AAC) is recommended. Â Channels: Choose between mono (1 channel) or stereo (2 channels). Â Rate: Digitized sound is made up of sound samples. The more samples per second, the higher the sound quality. To maintain quality, music requires a higher sampling rate than spoken voice because music uses a wider range of frequencies. Audio CDs use a sampling rate of 44.1 kHz. Â Render Settings: Choose the quality of the signal processing that will be used; higher quality settings take longer to process. Â Other options: To see any additional options specific to your chosen codec, click the Options button. if it’s available. Preparing Movies for Internet Delivery With QuickTime Pro, you can create movies so that they can be delivered over the Internet. You can deliver a movie over the Internet in two ways: Â With HTTP download, the movie is downloaded to the client’s hard disk. Fast Start is a QuickTime feature that enables users to watch or listen to media as it is being downloaded (long before the whole movie has been downloaded) from a standard web server to their hard disks. Fast Start works well for short-form movies where file size is limited. It ensures high-quality playback regardless of users’ Internet connection speeds, although those with slower connections will wait longer before media starts to play. Â Real-time streaming provided by QuickTime Streaming Server (QTSS) delivers media in real time over the Internet, from modem rates to broadband. No file is ever downloaded to a viewer’s hard disk. Media is played, but not stored, by the client software as it is delivered. You would choose real-time streaming rather than Fast Start for webcasts of live events in real time, delivery of long-form video, 24/7 Internet radio and TV channels, and other cases in which you don’t files stored on a user’s hard disk. QTSS uses the RTSP protocol.
- 47. Chapter 4 Exporting Files with QuickTime Pro 47 Preparing a Movie for Fast Start With QuickTime Pro, you can set up a movie to start playing from a web server before the movie has completely downloaded to the user’s hard disk. This is called a“Fast Start”movie. Set the Fast Start setting just before you distribute your movie; making other changes and resaving may undo the Fast Start setting. If the movie is in the format you want, you can set it up for Fast Start by choosing File > Save As and then selecting“Save as a self-contained movie.”If the movie is not in the format you want, you need to encode it first by following the steps below. To convert a movie and set it up for Fast Start: 1 In QuickTime Player, choose File > Export. 2 Choose“Movie to QuickTime Movie”from the Export pop-up menu. 3 Click Options and select video and sound compression options appropriate for web delivery. For more information, see “Customizing Video Export Settings”on page 43, “Customizing Sound Export Settings” on page 46, and the tutorials at www.apple.com/quicktime/resources. 4 Make sure the“Prepare for Internet Streaming”checkbox is selected and Fast Start appears in the pop-up menu. Preparing a Movie for Real-Time Streaming With QuickTime Pro, you can set up a movie to be streamed over the Internet. To do so, you should compress the movie so that its data rate is appropriate for the bandwidth at which your users will connect. Hinted streaming format is for use with QuickTime Streaming Server or Darwin Streaming Server. When you choose hinted streaming,“hint tracks”(information needed to stream the movie) are added to the movie. If the movie is already in the desired format, you can prepare a movie for streaming by choosing File > Export and then choosing“Movie to Hinted Movie.”If you want to change the movie’s format, follow the steps below. To set up a movie for Internet streaming: 1 In QuickTime Player, choose File > Export. 2 Choose“Movie to QuickTime Movie”from the Export pop-up menu. 3 Choose a streaming option from the Use pop-up menu. 4 Click Options and select the“Prepare for Internet Streaming”checkbox. 5 Choose Hinted Streaming from the pop-up menu.
- 48. 48 Chapter 4 Exporting Files with QuickTime Pro If you want to stream a QuickTime movie using QuickTime Streaming Server, you should use a web-optimized video or audio compressor to compress the movie file. All QuickTime compressors are compatible with QuickTime Streaming Server, but the compressors listed here are optimized to give the best results for delivery over the Internet. For a complete list of compressors that QuickTime supports, see the Products area of the QuickTime website (www.apple.com/quicktime/products).

Â Desktop: Creates a movie optimized for delivery to computers over broadband connections.
- 49. Chapter 4 Exporting Files with QuickTime Pro 49 4 Choose a poster frame option for the movie. The poster frame determines the still image viewers will see when they load the web page with the embedded reference movie. If you want to set a new poster frame before exporting the versions, click Cancel. Then navigate to the frame you want to use and choose View > Set Poster Frame. 5 Click Export to create the files necessary for the options you selected. The exporting process creates several files, including files for each version of the movie you select, a reference movie that will automatically deliver the correct version to the viewer, and an HTML file that contains a snippet of code you can use to embed the movie in a web page. All of these files must be copied to your web server, in the same location relative to each other and with the same file names, in order for the reference movie and HTML snippet to function correctly. Exporting MPEG-4 Files MPEG-4 is the latest worldwide industry standard for delivering professional-quality audio and video over a wide range of bandwidths, from mobile multimedia to high definition. When you want to create a file that will work with another MPEG-4 device, use QuickTime Pro to create MPEG-4 content by exporting a movie. To export a file to the MPEG-4 format: 1 Open the movie you want to export in QuickTime Player, then choose File > Export. 2 Choose“Movie to MPEG-4”from the Export pop-up menu. Note: To create an MPEG-4 movie that is optimized for use with Apple TV, iPhone, or iPod, select“Movie to Apple TV”,“Movie to iPhone”, or“Movie to iPod”from the Export pop-up menu. All of the MPEG-4 options will be set to the appropriate values for you. To adjust settings such as file format, compression, and distribution restrictions, click Options. The options you choose depend on the network over which you’ll deliver the file and the viewers’ connection. The following sections describe the options in detail. MPEG-4 Video Export Options When you export a movie to MPEG-4 format (by choosing File > Export and then choosing“Movie to MPEG-4”), you access the following options by clicking Options and then clicking Video. Â File Format: To ensure operability with devices made by ISMA members, choose “MP4 (ISMA).”For more information, go to www.isma.tv.
- 50. 50 Chapter 4 Exporting Files with QuickTime Pro  Video Format: Choose the video compressor (codec) you want to use to compress your video. For the highest quality at the lowest data rate (or the smallest file), H.264 is recommended. If you need the file to play on a device that supports MPEG-4 video, choose MPEG-4 Basic or MPEG-4 Improved, depending on the target device. If your source movie’s video track is already compressed, you can choose“Pass through”so that the video doesn’t get compressed again.  Data Rate: The more kilobits per second (kbps), the better the movie quality. For best playback, however, don’t choose a data rate higher than the available bandwidth.  Optimized for: If you choose H.264 from the Video Format pop-up menu, choose your intended delivery method from the“Optimized for”pop-up menu. This setting tells the codec how much the data rate can vary above and below the data rate you choose.  Image Size: Current maintains the source material size. To choose a size not listed in the pop-up menu, choose Custom.  Preserve Aspect Ratio Using: If you are changing the image size, use this option to specify an option in case the movie needs to be scaled to the new dimensions. Letterbox will scale the source proportionally to fit into the clean aperture, adding black bars to the top and bottom or sides as necessary. Crop centers, scales, and trims to the clean aperture. Fit Within Dimensions adjusts to the destination size by fitting to the longest side, scaling if necessary.  Frame Rate: In most cases, your video will look better if you choose a number that is exactly divisible by the FPS (frames per second) of your source. For example, if your source is captured at 30 FPS, choose a frame rate of 10 or 15. Don’t choose a rate larger than that of your source material.  Key Frame: The more often you specify a key frame (the lower the number), the better the video quality, but the bigger the file. If you choose MP4 from the File Format pop-up menu and H.264 from the Video Format pop-up menu, and then click Video Options, you get the following additional options:  Restrict Profile(s) to: If you need the file to play on a device that conforms to one or more of the standard’s profiles, check those profiles here.  Encoding Mode: Choose whether you want the best quality or faster encoding. MPEG-4 Audio Export Options When you export a movie to MPEG-4 format (by choosing File > Export and then choosing“Movie to MPEG-4”), you access the following options by clicking Options and then clicking Audio.  Audio Format: Choose your audio compressor (codec) here.

- 51. Chapter 4 Exporting Files with QuickTime Pro 51 Â Data Rate: As with video, the more kilobits per second, the better the audio quality. Â Channels: Choose between mono (1 channel) or stereo (2 channels). Â Output Sample Rate: Available only with AAC audio. It’s best to match the sample rate to that of the target device. Â Encoding Quality: Available only with AAC audio. The Good setting is optimized for the highest-speed encoding, for higher-quality, choose Best for 16-bit audio, or Better if your audio source is 24-bit. MPEG-4 Streaming Export Options When you export a movie to MPEG-4 format (by choosing File > Export and then choosing“Movie to MPEG-4”), you access the following options by clicking Options and then clicking Streaming. If you’re going to deliver the exported file using RTSP streaming, select“Enable streaming.” Streamed data must be sent in smaller-size packets. Some networks have limitations on packet size and packet duration. If your network provider gives you information about size limitations, you can change the packet size and the maximum packet duration to comply with your delivery network. Otherwise, use the default values. Exporting 3G Files QuickTime Player can import and play back files for use on 3G networks—high-speed mobile networks that enable multimedia to be sent between mobile devices. QuickTime supports standards for nearly any kind of 3G mobile network. To import a 3G file, choose File > Open File and then select the file. You can also open a 3G file in QuickTime by dragging it to the QuickTime icon in the Dock or double- clicking the file (Mac OS X only). With QuickTime Pro, you can export video, audio, and text to one of the many 3G formats that QuickTime supports. To export a file to the 3G format: 1 Open the movie you want to export in QuickTime Player, then choose File > Export. 2 Choose“Movie to 3G”from the Export pop-up menu. To adjust settings such as file format, compression, and distribution restrictions, click Options. The options you choose depend on the mobile network over which you’ll deliver the file and the capabilities of the viewer’s phone. The following sections describe the options in detail.
- 52. 52 Chapter 4 Exporting Files with QuickTime Pro 3G File Format Export Options After you choose File > Export and click Options, the first two items in the File Format pop-up menu are the standard formats.  3GPP is for GSM networks. With this format, you can use:  MPEG-4, H.263, or H.264 video  AAC or AMR audio  3G timed text  3GPP2 is for CDMA 2000 networks. With this format, you can use:  MPEG-4, H.263, or H.264 video  AAC, AMR, or QCELP audio  3G timed text  Movie fragments (enables playback to start sooner for longer movies, since only the fragment, not the whole movie, must fit on the handset) The remaining formats are provided for specific networks. With these formats, you can restrict distribution so that a file can’t be shared from the recipient’s phone (set this option in the Advanced pane). These formats may limit the acceptable file size or data rate; check with the service provider for more information.  3GPP (Mobile MP4) is for NTT DoCoMo’s i-motion 3G service. With this format, you can use the 3GPP options described above.  3GPP2 (EZmovie) is for KDDI’s 3G network service. This format provides the same options as 3GPP2 (described above), except for AMR audio support.  AMC (EZmovie) is for KDDI subscribers with AMC-capable phones. With this format, you can use:  MPEG-4 video  QCELP audio  KDDI’s text format 3G Video Export Options  Video Format: If your source movie has only one video track and it is already compressed, you can choose“Pass through”(so that the video doesn’t get compressed again).  Data Rate: The more kilobits per second (kbps), the better the movie quality. For best playback, however, don’t choose a data rate higher than the available bandwidth.  Optimized for: If you choose H.264 from the Video Format pop-up menu, choose your intended delivery method from the“Optimized for”pop-up menu. This setting tells the codec how much the data rate can vary above and below the data rate you choose.
- 53. Chapter 4 Exporting Files with QuickTime Pro 53 Â Image Size: If you’re sending the file to a mobile phone, choose one of the standards. Current maintains the source material size; the resulting file may not play on a mobile phone. To choose a size not listed in the pop-up menu, choose Custom. Â Preserve Aspect Ratio Using: If you are changing the image size, use this option to specify an option in case the movie needs to be scaled to the new dimensions. Letterbox will scale the source proportionally to fit into the clean aperture, adding black bars to the top and bottom or sides as necessary. Crop centers, scales, and trims to the clean aperture. Fit Within Dimensions adjusts to the destination size by fitting to the longest side, scaling if necessary. Â Frame Rate: In most cases, your video will look better if you choose a number that is exactly divisible by the FPS (frames per second) of your source. For example, if your source is captured at 30 FPS, choose a frame rate of 10 or 15. Don’t choose a rate larger than that of your source material. Â Key Frame: The more often you specify a key frame (the lower the number), the better the video quality, but the bigger the file. These additional options are available when you click Video Options: Â Re-sync markers: Adds re-sync markers inside the video frames to help with packet loss recovery when streaming. Â Encoding Mode: With H.264 video, you can speed up the compression process (for preview purposes, for example) by choosing“Faster encode (Single-pass).”With the default option,“Best quality (Multi-pass),”the codec determines how many passes are needed to compress the data for the best quality. 3G Audio Export Options When you export a movie to 3G format (by choosing File > Export and then choosing “Movie to 3G”), you access the following options by clicking Options and then clicking Audio. Â Audio Format: If your source movie has only one audio track and it is already compressed, you can choose“Pass through”(so that the audio doesn’t get compressed again). Â Data Rate: As with video, the more kilobits per second, the better the audio quality. Â Channels: Choose between mono (1 channel) or stereo (2 channels). Â Frames per sample: Available only with AMR audio, this option enables exported audio data to be packed more efficiently. Â Silence detection: Available only with AMR audio, this option detects audio portions with low signal levels and adjusts the data rate of the output accordingly. Â Output Sample Rate: Available only with AAC audio. It’s best to match the sample rate to that of the target device. Â Encoding Quality: Available only with AAC audio. By choosing Best, you can get higher-quality audio but it takes longer to encode.
- 54. 54 Chapter 4 Exporting Files with QuickTime Pro 3G Text Options When you export a movie to 3G format (by choosing File > Export and then choosing “Movie to 3G”), you access the following options by clicking Options and then clicking Text. These options are available if your movie has a text track (credits, titles, subtitles, and so on). Some mobile devices can’t play text in a movie. To allow the movie to play only if the text can be displayed on the receiving device, select“Require text capability on handset.”Deselect this checkbox to allow the audio and video to play even if the text can’t be displayed on the device. 3G Streaming Options When you export a movie to 3G format (by choosing File > Export and then choosing “Movie to 3G”), you access the following options by clicking Options and then clicking Streaming. To create a file for RTSP streaming to QuickTime Player, select“Enable streaming.”This option creates a hint track (instructions necessary for streaming a file). “Optimize for server”helps the server to process the file faster, but increases the file size. 3G Advanced Options When you export a movie to 3G format (by choosing File > Export and then choosing “Movie to 3G”), you access the following options by clicking Options and then clicking Advanced. If your file is in Mobile MP4 or EZmovie format, you can restrict distribution so that once the file is on a handset it can’t be sent or copied anywhere else. You can specify how many times the file can play back on the handset once downloaded, or make the file expire after a certain number of days or on a certain date. “Fragment movie”enables the file to download via HTTP in small pieces so that playback can start faster and so that larger files can be played on the handset (only the fragment, not the entire movie, must fit on the handset at one time).
