Well, normally that is what variable bitrate encoding is for. But what exactly did

Well that is not really something you have to tell to mencoder but more
precisely something you need to tell the codec mencoder is using.

I have tried 2-pass encoding using xvid and this was perfect for my needs

it does this perfectly selecting the perfect bitrate for every moment of the

If you havent tried this, try it, it is great. If not please let us know
