I'm still running into issues with converting DivX5.0 avis created with
vcr to high quality 700MB avis.
Originally (0.90pre5 and before), I would do a three-pass method
mencoder $infile -ovc frameno -oac copy -o frameno.avi
mencoder ${infile} -ovc lavc -lavcopts \
vcodec=mpeg4:vbitrate=${bitrate}:vhq:vqmin=1:vqmax=31:vpass=1 -npp lb \
-oac copy -o ${outfile}
mencoder ${infile} -ovc lavc -lavcopts \
vcodec=mpeg4:vbitrate=${bitrate}:vhq:vqmin=1:vqmax=31:vpass=2 -npp lb \
-oac copy -o ${outfile}
And get generally good results (actually at this point, I was converting
from DivX ;-) low-motion coming out of vcr).
At the pre6 mark (and also with pre7), if I do a 3-pass postprocessing,
I get the right size output, but the sound is out of sync and gets
farther out over the course of the movie. If I do a 2-pass without
specifying the bitrate, the movie ends up roughly 3x greater:
-rw-r--r-- 1 storm storm 618M Aug 24 22:53
lethal_weapon-cf.avi
-rw-r--r-- 1 storm storm 1.9G Sep 7 04:34
Lethal_Weapon.avi
Although the sound is correctly synced. Can someone tell me how to get
the proper sized files with the sound synced right?
Regards,
