Re: Thanks.

Except that DBDLabPro gives an average value of 2190 (VERY far from 1790) and a peak about 4364 where the graph shows a position above 5000 (possibly a diff in the unit used for both informations)

Don't forget that in a first approach mencoder has to be tested (again) for its rate control. So you can remove all filters that are here just to enhance quality.

That's why I asked the purpose of the "pnsr" filter in the command line but did not receive any answer. If the purpose is just to compute metrics while encoding, it does nothing but slowing the...

And enhance quality as the third pass introduces the "adaptative B-frame" feature. For testing purpose I don't mind doing 3-pass, just "to see".

I just want to be sure. The bitrate is given by what parameter ?
Isn't it this one :


IF yes, 4000 us not really what I call low bitrate.

IMHO there is no question like this. It has to be checked into the doc of the soft but for me the tool does not verify the same things when you give to it a muxed or an elementary stream.
