meaning of the vaf-file?

[FAMOUS]

hello,

why the cce creates the vaf-file? so there is atleast one pass more. when i encode dvds with divx/xvid, in the first pass an information file is created and in the second pass the video is created by using the information from the information file from the first pass.
so why the creating of the vaf-file is not one of the passes?

p.s.: perhaps there are a few mistakes in this post, sorry, i am german :)

Probably just an implementation detail. There's little point in encoding till the entire video is analyzed, because the program has no idea how to allocate bits. And the analysis pass goes faster without the extra I/O of saving a useless encode.
