Re: just a wondering question
 
My friend, I was just searching in an online translator for the word "accomidate" but I could not find it ... so I do apologize in advance if I understood you wrong.

AC3 comes with constant bitrates, like our mp2, so in case of 2.0 CH you can choose 128kbit as known. In case of 5.1 CH I wouldn't go below 384kbit but there have been some user reports (ok, also including me ;-) ) that a nice quality can be archieved when using 224, even at 5.1 CH but that also depends on the source.

So do your predictions as known using audio bitrates/sizes within your or the apps. calculations.

well I think I understand what u said :lol: anyway lol I have tok or cq matic to predic but I know that tok wasn't made for kdvd predcitin, I would use CQ Matic but I'm not 100% sure about that prog so maybe if u could be kind enough and tell me how I would use cq matic and calcumatic to predict right CQ for a dvd to kdvd.

Andy,
I've been using CQM and CalcuM for KDVD prediction without problems.
Eeeeh, that is, I find that CQM will produce great MPEG2 files for both KVCD, (S)KVCD and KDVD. I only noticed it produces files 1%-2% bigger than what I need for muxing.
Anyway just use CalcuMatic as usual to calculate your average bitrate. In the Audio options choose the value that DVD2AVI found for your AC3.
And that's it :wink: just like a regular MP2 file.
C ya
