Ok, so I've read some posts and learned a bit about the principles, but, something is still not clear...

- In V0, there is room for frames to go higher than 320kbps while sparing these bits on the low bitrate frames? (It can go a bit higher than 320 kbps limit)

- In 320 CBR, that doesn't happen, because the frame is literally stuck and can't got higher than 320 kbps, and thus it wastes on the frames that were with low bitrate. (It cannot go higher the 320kbps limit)

Is it still true that VBR would not be so consistent/precise as 320 in terms of choosing the right bitrate for a particular frame: eg: a frame needs 256 k but it "guesses" and calculates 250 k and then it was not truly consistent?

Thanks for answers.

As not to give the wrong impression...

"We" don't have a tie, one may be better than the other overall for any individual who can successfully demonstrate a difference. Furthermore, preference between two non-transparent encodings is absolutely subjective.

One should test for himself before making a conclusion as to which is better from a quality perspective and determining whether he belongs to the group you've designated as "we." Let's say that some particular individual cannot ABX anything including the most killer sample at -V2. Is -V0 better for him than -V1? The answer is no.
