Are their any Avisynth filters that read the Xvid logfile?

[trbarry]

Hope this is the right forum for this. I debated the Avisynth forum but thought it is probably only Xvid specific.

It would be nice to be able to add an extra pre-pass to my encodings, even for CBR. The idea would be to run the 0-pass and then, on the next pass, have conditional sections in my Avisynth script that would only apply certain filters to sections of the file that would otherwise be encoded at some user specified quant level.

Does anything like this already exist? Or anything that could be easily modified to do this?

I think ARCalculator does something like this, or so I've heard. I know it doesn't relate to the name but afaik that is it.

That actually sounds very interesting. You could maybe apply MipSmooth to very small frames under the assumption they were scenes with little movement.

Thanks. I haven't tried it yet but it looks like with a little tinkering I can probably get AR Calculator (AVS Optimizer) to do the job.

I had actually been thinking of a script that read the log file on the fly but the AR Calc way of just reading the log file and making the script should work just as well for my purposes.

This took could turn out to be very useful in creating a smart 2-pass CBR for my HDTV clips.
