Characteristics of digital video, Computer Graphics

Digital video can be characterized by a few variables:

Frame rate: various frames displayed per second. The illusion of motion may be experienced on frame rates as low as 12 frames per second, although24 frames per second use by modern cinema and 25 frames per second use by PAL television.

Frame dimensions: The breadth and height of the image illustrated in the number of pixels. Digital video comparable to television needs dimensions of around 640 x480 pixels.

Pixel depth: various bits per pixel. In several cases it may be possible to divide the bits dedicated to luminance from those utilized for chrominance. Conversely, all the bits might be utilized to reference one of a range of colours from an identified palette.
