I seem to be running into a rather bizarre issue when dragging and dropping AVI files into FCPX. Normally they work just fine, so long as they are under 2 minutes and 30 seconds in duration. Anything longer, and I get blank footage and no audio for the remainder of the clip. The videos I'm importing are all recorded by FRAPS while gaming in Windows, and there are no problems whatsoever when playing them in Quicktime or editing them using MPEGStreamclip. I'm led to believe it's a file size issue, as the videos in question run above the 2ish GB range, where anything after that point is read as blank. As an example, a 4 GB video that plays for around 4 minutes normally will show as a 2 minute 30 second clip with about a minute and a half of blank footage and no audio at the latter end. Given that the videos work everywhere except FCPX, it's clearly an issue within the application. Right now, I'm getting around it by batch converting each AVI into MOV files encoded using Apple ProRes 422 HQ and then using the clips, but it'd be a lot more convenient if I didn't have to transcode first. Any ideas as to what might be causing it?
