h.264/MPEG-4 to 2-pass XviD (.avi)

[lalala]

Hi!

I have a problem regarding HD which is an h.264/MPEG-4 stream.
I've spent lots of days trying to find out an solution to make an 2-pass XviD encode (.avi format).

I'm hoping you guys might have an idea how to solve this.

Link for an 14MB HD stream to play with: http://rapidshare.com/files/50524437/SVT_HD.ts.html

Thanks.

Edit: I managed to get that file to xvid 2-pass, my problem is with bigger files (with more moves).

You haven't qualified the problem at all.
the goal, the problems, the tools?

in anycase mencoder can do a 2 pass no problem,
audio sync concerns me a bit, and there's a reported broken frame
but:

mencoder hd.ts -o menHD.avi
-ovc xvid -xvidencopts bitrate=6000:vhq=4:pass=1:turbo:max_key_interval=200 -oac
 mp3lame -lameopts cbr:br=128:mode=0

mencoder hd.ts -o menHD1.avi  -ovc xvid -xvidencopts bitrate=6000:vhq=4:pass=2:max_key_interval=200 -oac mp3lame -lameopts cbr:br=128:mode=0

Also for some more info/inspiration, I know soopafresh has got some scripts to deal with avc .ts in a thread somewhere.
You could search for it.

Thanks alot 45tripp, it acutally works

I still have a problem though as source is 50 fps and i want to make it 25 fps without any blocks/hacks/slowdowns etc.
I know it's possible but i can't get it to work.

Any ideas?

Thanks
