I was looking around the VCD Help forums and found this thread. It seems like there having an argument of CQ vs 2-pass VBR. I thought u might find it interesting since your a big supporter of CQ over 2-pass VBR.
I think 2-pass vbr seems to be winnig...better go give your 2 cents..lol.

im sure variable pass VBR can be better, in some cases, but when considering the time and effort it takes to complete a VBR project, CQ definately blows everything away. hands down... my 2 cents. anyway, CQ takes like 6 hours as opposed to a very lengthy time with VBR.

Yeah, I saw the thread yesterday.
Banjabber, if I recall his name correctly, was just calmly explaining what CQ is all about and in simple terms and here's this moderator Adam, who thinks he is correct, blowing his stacks off not really comprehending what Banjabber was saying. It was so amusing, like I was watching a child throwing a tantrum when he cannot get what he wants
Anyway, I think this Adam is just stuck in a paradigm that even if you pound to his head what CQ is all about, nothing won't sink in.

In my meager understanding from reading the various links posted on the subject, VBR can only be better in terms of file size predictability. In terms of quality, it can only be at par with CQ at most. Why, because it is limited by its having to maintain an average bitrate that is subject to a limited availability of bits. And even if it has provided the average bitrate for a scene, that may not be enough to maintain the quality. It has to compromise between maintaining the average bitrate because it only has this much bits to work with.
CQ is not constrained with anything, it can pile on the bits even to the max cap for the rest of the movie if the scenes call for that much. It won't be thinking, "Oh , I better ease up on the bits because I'll run out of bits and I still have three quarters of the movie to go." CQ doesn't care about average bitrates, it only cares about maintaining the quality that you have set it to do.
