Thanks for the help guys. It DOES seem that it’s a codec issue, though as I say I’ve not experienced it before. Odd that AE should display the footage but not render it out. I found that Premiere didn’t even display the image, but Photoshop had no problem reading it and re-rendering out to an uncompressed quicktime file without issue. How is it one Adobe product can read a video file and others cannot..? AND that it was Photoshop that could figure it out and their video-based programs could not! Very odd, especially as the video was rendered out of premiere in the first palce as a simple DVPAL video.
Anyway, thanks for the tips… gonna keep my eye on this one!
