Body: <p>I'm trying to deal with some very old video files from a Mac OS 8-era CD. They have a &quot;.ms&quot; file extension, and can be played with the old &quot;Movie Player&quot; distributed with OS 8. But Movie Player won't export them to .mp4 or anything currently useful, and I haven't found a modern-day player/converter (VLC, etc), on either Mac or Windows, that will open them. I could update my old testing Mac to QuickTime 3, but I've long ago misplaced my QT 3 Pro key(!), and the free version of QT 3 doesn't do exports. Those were the days... BTW, these &quot;.ms&quot; files are not the same as &quot;.dvr-ms&quot; files, so there's no help there.</p>
  <p>Any advice? Maybe there are some settings for ffmpeg I've missed? Thanks!</p>

  (Asked by: username_0 on 2024-10-02)
  
  I'm trying to deal with some very old video files from a Mac OS 8-era CD. They have a ".ms" file extension, and can be played with the old "Movie Player" distributed with OS 8. But Movie Player won't export them to .mp4 or anything currently useful, and I haven't found a modern-day player/converter (VLC, etc), on either Mac or Windows, that will open them. I could update my old testing Mac to QuickTime 3, but I've long ago misplaced my QT 3 Pro key(!), and the free version of QT 3 doesn't do exports. Those were the days... BTW, these ".ms" files are not the same as ".dvr-ms" files, so there's no help there.
  
  Any advice? Maybe there are some settings for ffmpeg I've missed? Thanks!
