Banner usually a mix of motion graphics and videoVideo 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)

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)
