My video preview screen is solid orange. It worked ok for a few clips. Using version 256 installed the "fix" but can't see my video. What do I do? I've uninstalled and reinstalled several times without luck. Using 32 bit Win7 4gb.
Have you tried going to the ATI or nVidia site and downloading the latest drivers for your video card? This fixes problems like this more often than you might think!
This also might be related to your source video -- if it came from someplace other than a camcorder.
Thanks for your help. I have the current 7.7.1 version of QT. The preview display works for awhile then starts flickering orange and shortly thereafter all solid orange. Rendering at 720p .mp4 craps out also.
I deleted several clips that I thought may be "suspect". I then made several small movies (only a minute or 2 long) and spliced them together to finish my project. Perhaps I was just throwing too much information into too many tracks to a 4 year old Dell. Anyway, no display problem and rendering in MP4 - 720p and 1080p went without a hitch.
