Error:Unknown error

Issue
Premiere Pro produces "error compiling..." application failed to return a video frame"

Possible Solutions

 * Adobe technical support documents:
 * kb330380: Export to MPEG or DVD causes freeze or error "...failed to return a video frame" (Premiere Pro 1.x)
 * kb330725: Troubleshoot errors or freezes when you burn DVDs (Adobe Premiere Elements 1.0)
 * kb332331: Error: "Error compiling movie" during render or export (Adobe Premiere Pro, Premiere Elements)
 * kb332562: Troubleshoot creating and importing Adobe Dynamic Link compositions (Production Studio on Windows)


 * In the thread “MPEG export process : UNKNOWN ERROR” it has also been noted that having a Matrox capture card can cause the problem.

 * the same thing happens to me consistently when i'm exporting timelines greater than about 30 minutes: i get "unknown error". the solution that works for me is to delete the .xmpses file that's generated. then the mpeg files import into encore.

 * i discovered that the error was occurring at exactly the point where one nested sequence contained nothing at all on the timeline - the previous clip was set to fade to black, the next was set to fade in from black, and the intervening small space was simply empty. i added black video to that empty spot, and this error went away.

 * I found my solution. I had to Delete out all of my Preview Files, rerender and try again.

 * For me, the solution was to change the scratch disk from one hard drive to another. I have no idea why, but it worked!
