The point about transcoding, say, MP3->OGG is that the two codecs use different assumptions (psychoacoustic models, etc.) in performing the compression -- so transcoding often results in one codec trying to chase down and reproduce artifacts generated by t...

RC2 vs. beta4 (test)
Hi! I would like to share with you an interesting test result. I re-encoded a song 10 times (the 2. made from the 1., the 3. made from the 2.,... the 10. made from the 9.), with a beta4 (CVS 20010620) and with an RC2 (CVS 20010817) library version, 256 kbit/s mode, channel coupling disabled at RC2. The beta4 is very good at the 10. encoding too, but the RC2 has some interesting quality bugs. So,

Higher quality video - supporting greater than 8 bit color depth
Hi, I was wondering what are this forum's collective thoughts on the best way to support video color fidelity greater than what we have today. I am not a video developer myself. I edit video. A type of problems I come across fairly often, have to do with the limited color depth of the digital video medium. They often manifest themselves as "cartoonish" areas of adjacent flat

We will only be doing [A]YUV ordered planar encoding, no other order, not packed using one of several methods.
