[MPlayer-users] 2-pass HQ encoding with libavcodec

[Arpi]

Hi,

Who needs divx4 or xvid any more? :)
Thanks to Michael, the libavcodec encoder was nearly rewritten nowdays.
I've just encoded 2 chapters of the Contact DVD at 900 kbit, full resolution
(720x576x25fps) using 2-pass and it's very good quality!
(i've added 2-pass support today)

mencoder -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=900:vme=5:vqmin=2 -pass 1
  -nosound test.vob

vme selects motion estimation algo, best values are 5 and 4, don't forget to
set it!

also note, that it encodes at 33 fps on p4, good, ehh?

anyway it seems that 2-pass doesn't help so much, it's very good even at
1-pass encoding, just set vratetol to something bigger, good value was 40000
for me.

so, try it and tell us your opinion...
use last-minute CVS from both mencoder and libavcodec!
