I have a ProRes 422 HQ trailer clip that is about 70 seconds. I would like to add a 0.5s cross fade (to black/silence) at the head and tail of the clip. The output file must have the exact same characteristics as the input file.
Where I'm starting at is something like (in ffmpeg):
ffmpeg -i "concat:??|trailer.mov|??" -c copy output.mov
Is there a way to do this with ProRes 422 in ffmpeg. If not, what other tools might work for this kind of thing? Note: all the video files are on a linux server, so it's something I'd need to do via a command-line and not something like Final Cut.
Is this possible to do in Compressor via command line, or what might be the best starting place to try and do this?
