Hey David!

One suggestion I can make is to try and use the 'YUV4MPEG Stream' file format for rendering your video. I'm working with Panasonic P2 HD data converted into avid DNxHD format. To push my video back out to DNxHD I use ffmpeg commands via YUV4MPEG Stream. Then I push out my audio and then combined the video and audio via ffmpeg again on the command line. The idea behind using ffmpeg is you can control all the options for your video. It's a lot of steps but it's working for me so far.


Here's an example of my ffmpeg command I use in the "Use Pipe:" field for the YUV4MPEG Stream options....


ffmpeg -i - -vcodec dnxhd -s 1280x720 -aspect 16:9 -r 23.98 -b 60Mb -an -y '%'


...then I render out the audio separately, and finally combined the video and audio into a single file...


ffmpeg -i Scene02_dnxhd.mov -i Scene02_dnxhd.wav -vcodec copy -acodec copy Scene02.mov


This is probably overkill for what you're trying to do, but it's one possible solution.


Here's a few ffmpeg pages I found helpful....

This report looks very similar to one I just sent on .mov formats, except the players for the most part throw up their hands and won't accept the video, perhaps because of a missing plugin. In any case, the video is huge, and not just a bit-for-bit copy of the input avi. Why is that?

from the command line: "cinelerra fan.avi"
(you can get this file at http://www.speakeasy.net/~morse/fan.avi <http://www.speakeasy.net/%7Emorse/fan.avi> - it is only 500kB.
Settings>Format 512x384
File>Render to "fanr.avi", File Format = Microsft AVI, Create new resources only. Ignore three errors about "virtual int FileMOV::read_frame(VFrame*) quicktime_read_frame_quicktime_decode_video failed, result:" One kind of expects this to be a file copy, since nothing has changed but in fact creates a file that is 20 times larger, its 10 gigabytes!!

cinelerra CAN play it.
youtube CAN play it (only tested on amd64)
totem FAILS to play it (see below)
vlc FAILS to play it (see below)
xine plays it with CORRUPTED COLORS (see below)


Reproduced on the following installs:
*** Totally fresh install, Ubuntu 8.10 + security updates + akirad repository 'cinelerracv-smp'+ Medibuntu w64codecs on amd64 machine + xine-ui package
*** Old Debian Etch x86-32 system.

TOTEM FAILURE NOTES:
It just plays the sound, then at the end errors with "The playback of this movie requires a video/x-avi-unknown decoder plugin which is not installed." Note: On the old Debian Etch system, instead I got the corrupted colors

VLC FAILURE NOTES
"no suitable decoder module for fourcc `yuv2'. VLC probably does not support this sound or video format.".

XINE FAILURE NOTES
The colors look like http://www.speakeasy.org/~morse/cinelerra-colors.jpg <http://www.speakeasy.org/%7Emorse/cinelerra-colors.jpg>
