While your fixing things for me, on the same sort of subject, when importing the ffmpeg ProPres files into Final Cut I allways get this warning message:

"The following media files are not optimized for Final Cut Pro."

Any ideas of ways to fix this warning me, I know you can turn off the warning in FCP, just wondered if there was a way to 'fool' FCP into 'liking' the files.

Kind regards.
