Screen ratio 16:9 – This has been chosen because is it usually the screen ratio for most DVD’s.
However if it was being viewed on a computer as such, the screen would then be a ratio 4:3.
Frame Rate – From the research, this is what I found about frame rate :
To record moving pictures, DVD-Video uses either MPEG-2 compression at up to
9.8 Mbit/s (9,800 kbit/s) or MPEG-1 compression at up to 1.856 Mbit/s (1,856 kbit/s).
[7]
The following formats are allowed for MPEG-2 video :
At 25 frames per second, interlaced (commonly used in regions with 50 Hz image
scanning frequency):
720 × 576 pixels (same resolution as D-1)
704 × 576 pixels
352 × 576 pixels (same as the China Video Disc standard)
352 x 288 pixels
At 29.97 frames per second, interlaced (commonly used in regions with 60 Hz
image scanning frequency):
720 × 480 pixels (same resolution as D-1)
704 × 480 pixels
352 × 480 pixels (same as the China Video Disc standard)
352 x 240 pixels
The following formats are allowed for MPEG-1 video:
352 × 288 pixels at 25 frame/s, progressive (Same as
the VCD Standard)

Hostel part 2
- 1. Salford City College Eccles Centre Creative Media Production Use of text: Interactive Menu – Hostel Part II (Title, Credits, animated captions, stings, indents, interactive menus, web banner) Brief description: Closed off area, which is small which can give the sense of seclusion for the audience, What do you see? claustrophobia can be sprung into mind making the audience seem a little more scared about the film. Gates which look like prison cell gates which also can involve the audience as they may not want to go in prison. It also gains the control of seclusion as there seems to be nowhere to go. Blood splodge on the floor, spread across signifying it’s not a nice place to be. Flickering licks on the ceiling gives of the horror look as if the lights are flickering then it suggests they can go off at any minute leaving it all pitch black. Door slamming shut and opening to reveal different characters showing each individual to give the audience a sense of what kind of people to expect during the film. Subtitles shaking with bloody splatter effects behind subtitles of blood drops re- enforces the genre that the film will be. Electric sparks coming off the walls off the wires showing that the place where we see in the main menu, isn’t a very nice place to be and isn’t somewhere where people would want to be. Techniques used: Movement is used by the camera and objects within the menu giving it the edgy feeling Animation, Visual Effects, Colour Rendering, making the audience be on the edge of their seat as they watch the film. Graphics, Movement Visual Effects – it looks old, scary, abandoned like, claustrophobic, darkish room with a dim/flickering light effects, horrifying effect using mysterious characters 1

Salford City College Eccles Centre Creative Media Production Advanced techniques: Rotation isn’t used much yet a 180 has been used Blur, Sharpen, Distortion, Rotation, Opacity Sharpen is used on a focus on the gates Blur is used when the camera itself moves to give off a distortion look Technical comments: H.264 / MPEG-4 AVC Video Format, Screen Ratio, Resolution, Frame rate, Compression Overview H.264 is also known as MEPG-4 AVC. H.264 uses the latest innovations in video compression technology to provide consistently crisp and clear video for the best possible viewing. Pros H.264 delivers incredible video quality at data rates one-fourth to one-half the size of previous video formats H.264 offers dramatically lower bit rates and better picture quality than MPEG-2, MPEG-4 or H.263+ It is 2X times more efficient than MPEG-4. and file size is 3X times smaller than comparable MPEG-2 Codecs It is easy to integrate and covers wide range of picture format. Hence used in large application segment. Cons H.264 requires longer encoding time It is certainly not constricted and low-bandwidth friendly More Hardware overhead is also one of the limiting factor Licensing agreements are complicated. 2

- 4. Salford City College Eccles Centre Creative Media Production 352 × 240 pixels at 29.97 frame/s, progressive (Same as the VCD Standard) Video with 4:3 frame aspect ratio is supported in all video modes. Widescreen video is supported only in full D1 resolutions. This shows each of the FPS. Resolution – From looking at the research I have done, I cannot be exactly certain, as the resolution was 720 x 480 on nearly every page I looked. The image itself didn’t seem to be in HD. Video Format – From the research, the DVD-Video is a consumer video format which is used to store digital video on a disc. The video format is encoded in MPEG-2 format. Looking into the video format more, MPEG-2 is the main video format for DVD-Video, however, MPEG-4 seems to be the best fit in terms of the generation today. MPEG-2 Overview MPEG-2 is a standard for broadcast-quality digitally encoded video. It offers outstanding image quality and resolution. MPEG-2 is the primary video standard for DVD-Video Pros Excellent image quality Cons Very few people are currently capable of viewing MPEG-2 Licensing fees (typically US $0.04 - $0.40 per unit) are required to distribute MPEG- 4
