Comptest with nero recode ?

[hubereevez]

Hi,

I did like this compressibility test under Gknot and xvid,divx.

Is it possible with h264 ?

Thanks

I doubt that something like a comp test would give any usefull data if one wants to use CABAC (Context Adaptive Binary Arithmetic Coder),..

There is nothing that prevents it except we did not provide any tool to do it :(

It's fairly easy to do with all statistics from the encoder ... It's like many usefull tools (muxer/demuxer, cutter/joiner etc.) maybe in a new version if there is a strong demand for it.

Thanks babayaga

CABAC (Context Adaptive

Mhmm i did though about that. It's the same thing when you try to test compressibility, with tools like mvtools or masktools in your avisynth script, isn't it ?

Thanks anyway

CABAC has nothing to do with the feasability of a compression test.
While some filters can produce unpredictable changes in compressability, CABAC is very consistent at 10(+-3)% improvement.
And if you decide that the uncertaintly is too great, you don't have to disable CABAC in the test; it's only a small fraction of the encoding time.
