I'm new to this forum and still haven't seen a solution to my problem. I have Vegas 6.0 and am working on a football highlights video with music and text. The video is approx. 56 minutes long and the problem that I am having is that whenever I open the project some of the video clips appear as black boxes in the timeline and in the preview pane. I have tried replacing the file, but it does not help. I am fairly new to video editing and have been successful creating DVDs with photos, but video is giving me a headache. Any help out ther?
