I tried to do that, but I got lost :( I think the problem could be related to the rate control settings, but I am not sure. Ok, I think I tracked down part of the problem: it seems that the deblocking filter is involved (in ffmpeg, it is disabled by default. In mencoder and in the x264 CLI, it is enabled). Adding the "-loop" option to ffmpeg, the quality improves a lot (BTW: are "loop filter" and "deblocking filter" the same thing?).

Can anyone confirm?

        Thanks,
            Luca
