I am trying to play back some 1920 X 1080 QuickTime Photo-JPEG files in both ProTools and QuickTime 7.6.6 and am seeing only a black screen. These were generated using Final Cut Pro. However, when I open the same files in QuickTime 10.1, I can see the content. Furthermore, when I export them as H.264 files from QuickTime 10.1, I can then play them back in QuickTime 7 and ProTools. Does anybody have any idea how I can look at these files using QuickTime 7 without having to do the exports?
Sorry for posting here, but the Mac OSX forum seems to have little traffic and these WERE generated using FCP.
