I get an “Export Failed” error at the start of my encode. What went wrong?
Apple disabled the Export Componets ability to send detailed alert messages to the user in QuickTime7 and so we write all error messages to the PtHdMpegExport.log file in the root of your boot directory. If you look at the bottom of theis file, you may see an explanation for the failure. Common demo failure messages are that the demo has expired or that your file exceeds the maximum demo length. Common release messages are that the detected frame rate is not a valid frame rate.
