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:
All the information in your first mail of this thread should be
sufficient. Many of the developers there have read access to mplayerhq
ftp, so you won't have to upload anywhere else.
