Hi there,
What r B Frames, and how does it affect the movie quality? All I hear is B frames deteriorate the quality? How does 1 modify the number of B frames?
Also, how does one tweak the quality of a movie using XviD 1.0.x? it depends on the movie :-? how? what does it depend on?
I fram is full quality. like a full picture. b frame is a fragment of that, the necessary detail that will make the motion.
take it like this. in a scene where the dude talks. which part of his body is moving ? his lips, then the frame will take that moving pixels, something like that.
if you set b frame to zero then you'll get I and P frames only. b frames is good to compress the video. still pictures of it may look bad, but while motion it hardly noticeable, cause the way it is decoded.
you don't have to transcode scene by scene, what i meant is that certain parts that looks crap, like credits can be compress more, that is what the zones settings are for.
Debbs, check out the unofficial XViD FAQ, it explains XViD settings in great detail and also suggests settings to use for different cases, etc. It's a hell of a read but will greatly further your understanding of XViD:
