Document Summary

Sample the temporal dimensions of the video, sampling= frames. Higher frame rate means more accurate motion is sampled. Also means larger file size! (more samples, the higher the quality, but it means we will have a bigger file size) Each pixel gets assigned a colour, maybe just 2 colours (black and white 1bit colour) or maybe 16 million colour (24 bit colour) Clear sheet material on which images were drawn by movie animators (hand drawn) They are placed on a stationary background. We can reduce the number of frames. Increase the frame rate (speed of animation) ie 8fps to 12fps. Add more frames (but keep the frame rate the same) Lower the frame rate (go from 20fps to 5fps) keeps the number of frames as original but stretched out the movie. Animating a graphical object by creating smooth transitions between various keyframes, the frames that indicate the beginning and end of an object"s motion path.
