doom9 perhaps? http://forum.doom9.org/forumdisplay.php?f=77 > The other thing I find weird with -preset is that one can use -crf > setting with it.

As far as my experience tells me, the presets control speed versus size, at (approximately) constant quality. So "-preset veryslow" and "-preset ultrafast" should show the same image quality. There are test measurements out there to prove it, IIRC. You then use "-crf" to vary the requested quality. Indeed, asking x264 folk would be better. :) Moritz _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
