This has cropped up recently in a couple videos I've done. When exporting I'll get errors (fails at a certain frame number). What I've discovered is that it happens where there is a dissolve. If I delete the dissolve, it exports fine. If I put a new dissolve on the transition, the problem comes back. If I replace the dissolve with another effect it exports fine. Anyone have a clue as to what is happening or what I can do to solve the problem?
