RGB and YUV

[techz]

Most guides say that YUV is better, but isnt RGB more realistic or accurate

Any way to tell what was used to encode the avi, i ve tried GSPOT it cant tell

Well, RGB is more accurate. Too bad no codec supports it. Neither DVD, DivX nor XviD supports it, but uses YV12!

And that's why all guides recommend YUV processing. You don't need to convert the colorspace twice (YUV->RGB->YUV). As there is less bits/pixel in YUV that makes it faster. You have less calculations that will introduce errors, but the errors does have a slightly larger impact on the final video. But even then almost any errors introduced this way will not be visible or noticeable in 99% of the frames - if you look at them one by one. And when you play the video then it will be even less visible.

Remembering Rule 1, I wanna READ more on these. Basic to advanced stuff. Some links are all I want.

Thanks, PROs.
