I am a video guy. I don't know flash. However, I am working with a graphics guy who doesn't know video. There is the problem. He has created a flash animation at video resolution (720 x 540 - 30fps).
The piece ultimately needs to be delivered on a DVD, so we are trying to get the animation dumped out as a DV compressed .mov file. When we try to export from flash, we have all the settings correctly, but all we get is a blank white animation.
