    {detectedFileFormat === 'mp4' &&
  1. Change output Format from MP4 to MOV
    2. }
  2. Select a different output Format (matroska and mp4 support most codecs)
  3. Disable unnecessary Tracks
  4. Try both Normal cut and Keyframe cut
  5. Set a different Working directory
  6. Try with a Different file
  7. See Help
  8. If nothing helps, you can send an Error report
