Well, JPEG was intended to be a compression method that will allow to compress the heck out of a picture without much lost, I believe from around 2:1 is lossless and anything above 35:1 is usually lossy. 100:1 can be achieve but the picture will lose much quality, definition, color, etc.. Then MPEG was a similar idea but adding motion and sound to the equation. MPEG I beleive tried to accomodate the current CD ROM transfer rate as part of the format (so movies could be played using CD's). But since sound is a tiny bit of the storage problem in motion. Enter the real bright engineers from various companies that created a format M-JPEG or Motion JPeg. Since all an animation is a bucnh of pictures shown one after the other. Several manufacturer created boards that compress and/or decompress JPeg images at 30 to 60 frames per second (nifty eh?). There are a bunch of other lossy formats in both still and motion. These happen to be standards. My 2 cents. Eduard VIS
