2006-05-23 16:18 - Two-pass MPEG4 encoding with mencoder
I keep forgetting this, so I'll put it here for everyone (including me) to see:
mencoder dvd:// -o movie.avi \\
-oac mp3lame \\
-ovc lavc \\
-lavcopts \\
vcodec=mpeg4:mbd=1:vqmax=10:lmax=10:keyint=130:vpass=1:turbo \\
-sid 3 -aid 130 \\
-vf scale=720:405,expand=720:576:0:25:1 \\
-spuaa 4
For the second pass, change "vpass=1:turbo" to "vpass=2".

That's true. However, the disk space earnings are marginal, as the second pass just overwrites the file from the first pass.
And I like playing the first pass while it's encoding, just to see whether it's doing the right thing and to check I didn't mess up any options such as the audio and subtitle languages ;-)

You don't need the first output file, so you can redirect it to /dev/null
