Will the fade-in/out add to the duration of the clip or take effect on the first and last 0.5 seconds of the existing clip?

@Gyan It wouldn't add to the duration.

Then the easiest way is to use the fade filter and re-encode the video.

(Asked by: username_0 on 2021-03-14)

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?
