Twice this has happened now: Trying both TMPGEnc Pro AND Cleaner 5, a finished MPEG2 file simply goes black at some point. (The AVIs were created in Premiere 6, captured with Pinnacle DV500 using the Pinnacle DV AVI codec.) In both cases, neither program actually crashes. They encode the whole clip. In TMPGEnc, you can actually watch the encoding progress and SEE the preview go black while the progress bar goes on. Any ideas on how I can avoid this?
