Document Summary

Sequence of images that create illusion of movement when played in succession. Each individual still image is called a frame. Easier to show somebody how something works then to try & explain it. Simulation of movement through a series of pictures that have objects in slightly different positions. Frame: s(cid:374)apshot of (cid:449)hat"s happe(cid:374)i(cid:374)g at a parti(cid:272)ular (cid:373)o(cid:373)e(cid:374)t. Frames per second (fps) self explanatory: movies: 24 fps, tv: 30 fps 9000 frames for five minute cartoon, computer animation: 12-15fps, less than 12 is jerky. Each frame is sampled into discrete samples & each sample becomes a pixel: sampling process. Multimedia & communications lecture notes - cs1033: more samples = better quality + bigger file sizes. Each pixel gets assigned a colour, maybe just 2 colours or maybe 16 million colours: Can sample the temporal dimensions of the video. Higher frame rate = more accurate motion is sampled + larger file size. Indicates the playback speed of the animation in fps.
