I have been working on a project for a few weekends now, just a little skit thing for fun. It's 13 minutes in total, 8-tracks of video and 3 audio. I have no problem playing it in VideoPad, and I have not deleted any clips or anything, the project is intact in VideoPad - but when I export it (and I have tried MP4, MPG, and none have worked in Windows Media Player or VLC) random parts are blacked out. No video in these parts, but audio all throughout.
Is there any way to fix this? It's very frustrating, especially as I've never encountered this problem with any of my other projects.
