My problem seems to be very stupid, but it took me the whole day and I still can't find out what's wrong with the video tracks.
I think It happened when I clicked on some place on the track. It seems like when you simply mark a track, e.g. when you want to arrange track motion. Here's the shot of it: http://i169.photobucket.com/albums/u...tureWiz005.jpg. But here comes the problem. There is no video in the preview box, when I click on "play", there is only audio. I tried to restart Vegas, then open new project, open another project, add new track... nothing happened. There were always being formed just the "marked" tracks, which Sony Vegas "ignores". When I render the video, the same problem - no video, just sound.
I clicked on every possible place on the screen, also tried menu, preferences etc. but I couldn't find anything what could be connected with the problem. Uninstall and re-install S-Vegas is the last thing I'd like to do.
I'm using Sony Vegas Pro 8.0
I'd be grateful for any ideas. Thank you very much.
