Body: <p>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.</p>
  <p>Where I'm starting at is something like (in ffmpeg):</p>
  <pre><code>ffmpeg -i &quot;concat:??|trailer.mov|??&quot; -c copy output.mov
  </code></pre>
  <p>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.</p>
  <p>Is this possible to do in Compressor via command line, or what might be the best starting place to try and do this?</p>

Title: Add a cross-fade to a ProRes clip

  (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?
