My video events have gone blank. I'm at 40 minutes on an hour video with tons of Transitions, Media Generations, etc. I have tried other videos with same result so problem is in software. I was Had either Illustrator or Photoshop up at same time, which I have been doing for months. The only thing that I can think of is that I accidently activated Vegas while working on the other programs and changed some parameter in Vegas. I cannot come up with a correction.
Help!
