What to expect

  • A remux with ffmpeg -c copy copies video and audio tracks unchanged - no quality loss and near-identical file size.
  • QuickTime Player's Export always re-encodes to H.264 or HEVC, which is slower and may produce a slightly larger output file.
  • .mov is not widely supported on Windows or the web; if the file goes to a Windows machine, keeping it as .mp4 (or renaming .mpeg4 to .mp4) is usually better.

Frequently asked questions

Is converting `.mpeg4` to `.mov` lossless?
Yes, if you use a remux such as ffmpeg -c copy - video and audio are not re-encoded. QuickTime Player's Export re-encodes, which causes a minor quality reduction.
Will the `.mov` file be bigger than the original?
A remux produces nearly the same file size. A re-encode through QuickTime Player can be larger depending on the export bitrate.
Can I convert `.mpeg4` to `.mov` on Windows?
Yes, with ffmpeg or VLC. QuickTime Player for Windows was discontinued in 2016 and should not be used.
Is `.mpeg4` the same as `.mp4`?
Yes - .mpeg4 is just a longer spelling of .mp4; the container and codec are identical, and renaming the file is safe and often all you need.
