Just to summarize for posterity, here is what works for me:
I load the files from my 7D into Cinelerra patched to read
SOWT audio.
I edit in Cinelerra.
I render audio to a wav file 16 bit linear audio.
I render video to uncompressed RGB in a quicktime container.
I user qtstreamize to move the moov
out if GPUs/ open/GL/ linux can work together.
Cheers

Well, first because I work with TIFF files in 16 bits, and I can use either RGB
or RGB float on them, and on the vectorscope it makes a hell of a difference
compared to 8 bits.
Second because I use them as a digital intermediate for 16 mm scans.
Once I have done my color corrections/ grading the

This is something I do, regardless of the target format. The reason is
that creating a proper video stream is an art in itself. Even if a video

Hi Mark
I never managed to use the internal H264 encoder properly.
I export with a yuv4mpeg pipe
Here is the script I am using

x264 --sar 1:1 -m 6 --me umh -b 4 --bitrate 24000 --threads 4 -o $file

I'd like to hear from some users about what you are using to render HD
files with the current version (git jt6 2009-12-10). I've tried the
following for
my 1080p29.97 files.
H.264 does not seem to work, with no video output.
Uncompressed RGB works, sent to a quicktime container, but the
PCM audio
