so the variance in quality of recording between a vhs tape & DSS/Cable box is drastic. i think the quality of the vhs tape also has allot to do with it because as a tape gets older, there tends to be more abnormal colors on playback (greens, fuzz, etc)...
If you're trying to compress crappy quality video, you'd benefit if you clean it up with a filter first (else you're just wasting bits encoding noise).VirtualDub would be the obvious tool to do it.
also, maybe becuase it was recorded by a unsteady hand using a one of those vhs cam recorders(?)...as such, instead of people just moving, you get the whole image canvas also moving becuase of the 'unsteady hand' when recording.
Interesting point! I guess if the picture is moving around more than desired then maybe you're killing CPU cycles by having to use a wider motion search in the MPEG compression to achieve the same result. It'd be interesting to take a "shaky" video, software image stabilize it, and do an MPEG compression time/size comparison.
