I'm interested in looking at your source material, but don't have read
access to mplayerhq ftp. Is there any way you can upload it to a public
server somewhere? If you're desperate, feel free to contact me off-list
and I'll set up a temporary account on my system that you can scp to. I
can't guarantee anything, but I haven't come across any material of
resolution similar to yours that I couldn't get great quality at
vbitrate=800, much less 1200.
Also, you can try posting to the ffmpeg-devel list:
