what is VAF file that CCE create and where is the m2v file?

[wizzy]

i am using DVD2DVDR and CCE started and he is making VAF file
what is VAF file and where is the M2V file?

[dhluke]

I think the vaf file is like the index file for the video. It will scan the video and tell the encoder the bibrates. The M2V file will come after the vaf file is done.

what!! this is not the encoding?!?!
lucky me i have dual cpu system and its only 1.5hr (VAF)...
but other people??

Actually, it depends. If you're doing CBR or 1-pass VBR, then the vaf file and the m2v file are created at the same time.

Once a vaf file is created, you can do a multi-pass encode using that same vaf file.

If you do a multipass encode with no vaf file - the encoder does a "0" pass to create the vaf file.

The var file is much more than an index - it contains information about the complexity of the scene, and it's updated with each pass - that's where multi-pass encodes "remember" what bitrate has to be given to what scene, and how it "learns".

thanks....it just start to encode the movie i have 2Hr left....
I hope the quality will be good.
I am comparing between DVD2DVDR and DVD2ONE

I do 1 pass VBR all the time, and the .VAF file is created first, followed by the .M2V file. It takes the same amount of time to create the .VAF file, then it does the .M2V file. It usually takes about 1 & 1/2 hours for the .VAF file, then the same for the .M2V file. I wish they were created at the same time. Maybe with CBR they are, but not with 1 pass VBR.

i am using 2Pass VBR

[wizzy]

done....supper dupper results with DVD2DVDR using CCE encoder
tooks a while but it looks good!

DVD2ONE was faster avcorse and i ended with 4.36GB the quality was almost the same to the original to.

both of them are good for backup DVD9 to5...its all matter of time...

[VidGuy]

Wizzy - you're not using the one-pass VBR where you define the quality you want - you're using 1 pass on the multipass VBR - they're not the same.

If you choose the single-pass VBR, it will ask you for a quality number and it will create the VAF and M2V at the same time. You just don't get to choose the bitrate in this mode.

Essentially the VAF file is created during the first pass. If all you have is one pass (CBR or 1-pass VBR) than at the end of that pass you have your m2v and your .vaf file. If you do any form of multipass encoding than after the VAF is created during the first pass, it immediately starts the 2nd pass, overwriting the first m2v file, and it repeats this process with each additional pass. It overwrites the previous m2v with the new one, and updates the information in the VAF with each new pass.

CCE's way of naming the # of passes is kinda confusing. If you set it to 1 pass VBR you are really doing 2. Its always one higher than what you set, so according to the manual there is no point to ever setting this higher than 3 (=4 pass vbr.)
