When using the default prores encoder in ffmpeg - kostya - I can't seem to get the vendor flag such that the clips can import to Final Cut 7 without prompting the "not optimized" error. I know that it's not an issue, but such things tend to scare editors.
Going by Kostya's instructions from his blog (http://codecs.multimedia.cx/?p=388) and using the -vendor:v ap10 argument I still get the error when importing to FCP7. Has anyone found a way around this?
