The What do you see? three boys are doing several tricks on their skateboards and the camera slowly moving to the front of them. This is done to show BBC One viewers something they might see on that channel because there are one or two programs like what we see in the graphic. Techniques used: The only technique really use is movement, the movement of the boys on the skateboards and Animation, Visual Effects, Colour Rendering, the movement of the cameras surrounding them. We slowly see more revealed of them as the Graphics, Movement graphic nears it end because the camera moves slowly to a better angle where we can see more.

Compositing video - When there are several different clips of video are layered over one another to create a single image. Interactive Menus – DVD Interface or Interactive Menus on a web page Ident – The ‘call sign’ of a channel or production company to identify themselves on screen, usually shown before a programme. Animated Captions – Animated Graphics layered over an image / video Web Banners – A form of web advertising that is embedded into a web page. They are used to attract a viewer to their website. A Web Banner usually a mix of motion graphics and video Video Format - 3 Main Formats HD, PAL, NTSC. HD is the highest resolution (720 or 1080 vertical lines in the image). PAL is the UK Standard definition image (576 vertical lines). NTSC is the US Standard definition image (480 vertical lines). Now in the digital age we now look at video format in terms of pixels (i.e. High definition 1080; 1920 x 1080 or 2,073,600 pixels) 2
- 3. Salford City College Eccles Centre Creative Media Production Screen ratio – Standard TV ratio is 4:3; this means that for every 4 units wide it is 3 units high. It is likely that the screen ratio will be Widescreen (16:9) in a cinematic sequence. Resolution – The amount of detail in an image or signal, such as Standard TV Definition and High Definition. See Video Format. Frame Rate - The number of video or film frames displayed each second (frames per second; fps). PAL frame (standard UK TV) is 25 fps, NTSC (standard US TV) is 30 fps, film is 24 fps. This means as NTSC updates more regularly there is less strobing (jerkiness). Compression – The use of Codecs (WMV, DivX) to reduce the file size of a video by a variety of methods. This sometimes means a loss in image quality (a “lossy”). Codecs are found in Video Cameras, DVD players / recorders, Editing Packages, Video upload sites) 3
