Thanks, now finally I understand where the GOP fits.

I was advised some time ago (by Luca, if I'm not mistaken) about the
following options, which should improve the quality from the start:

        c.mb_decision=2;//FF_MB_DECISION_RD
        c.noise_reduction=250;
        c.pre_me=0;
        c.me_method= 5;

I think the mb_decision relates to the -mbd 2 flag you told before about. Do
you know about the other options as well?

Regards.
