KVCD: Low average bitrate?
I'm some threads I see people talking about setting the MIN bitrate at 0,57 * the average bitrate 8O
What is the purpose of this, and when should you use it (or not)?? Is 0,57 a fixed number, or should that be calculated in some way? Tnx for any help! |
Using MIN=0.57*AVG and MAX=2000 is a way to help CQMatic to be very accurate in computing optimal CQ for your encoding.
It is not mandatory at all (I always use Min64-Max2300) but it helps a lot. And theses values were found after many tests. |
@All,
If you are using X3 mode for prediction in CQMatic, you don't need to set MIN as (0.57 * average). The longer prediction takes more sampling, and the results are more accurate, no matter what you set MIN bitrate to. -kwag |
