I had the same problem, and did quite a bit of digging which I think will help find the problem in version 6.2. Source file is an .mp4 at 1080i 60fps If I add the file to the project and apply audio enhancements, everything is fine on export. If I add a gradient blank of 3 seconds before the video, it previews OK If I add a text clip as a second track with a transparent background, it previews OK... BUT, here is the clue, the caching indicator stops at the end of the 3 seconds (and so does the export). Similarly, if I add the blank and text at the end, it would stop there. May have something to do with adding a fade between the blanks and video as well. If I do things so the caching makes it to the end, then export does too. Getting rid of the blank on video track 1 and moving the text from video track 2 to 1 solved my immediate problem. There seem to be some interaction between multiple tracks, the fade, and the text/blank interaction that hangs things up. During the stuck period, the CPU is still very busy, but it will never complete.
