zone/credits settings for xvid?

[ivanova]

Like the title said - Is there any way to make xvid encode the credits at a lower bitrate? I'm useing mencoder, but if transcode can do it I'll use that.

thanks

Hmm, I would like to know the exact same thing. I'm using dvd::rip and thereby transcode. Am also using xvid.
Someone must know how to do this.

Thanks!

AFAIK, this has to do with the corensponding transcode/mencoder xvid_export_modules.
They still lack support for zone configuration.
But if you desperately want to encode credits at smaller bitrates you can do it manually, that is, encode your clip up to where the credits start and then encode the rest at a different bitrate. All you have to do afterwards is join the 2 files.

E.g. with transcode you could use '... -c 0-155000 -o main_movie.avi' (assuming your credits start at 155000) and then '... -c 155001-156000 -o credits.avi' (assuming the clip ends at 156000), and then join the two separate files.

[edit]

As long as you don't use different xvid settings for the second clip, like Q-Pel, GMC, etc (appart from desired bitrate of course) the joined file will also be MPEG-4 compliant.

Yes this is what I do in the meantime :(
The xvid zone settings are very usefull though and should be implemented. If I knew how, I'd do it myself ;)

BTW: What do you use to join the avi's. Last time I looked most proggies had a problem with the last two frames when using bframes_max = 2. It resulted in the last two frames being lost and the clip getting shorter. Not really a problem with credits, but still...

BBTW: Any way to join matroska files?
