Not every media player supports all video file types. Same is the case with QuickTime. When a video file format is not supported by QuickTime, Final Cut Pro, iMovie or other Mac software, the video won’t open and give error.

For example, MKV or MTS files won’t open in QuickTime as it doesn’t support these formats. While iMovie can only open 3GP, AVI, M4V, MOV, and MP4 videos.

Hence, if the Mac videos are giving unsupported codec or file type errors or just don’t open with your media player, try the below workarounds:

  1. Play Mac video in a different player. Try VLC Player or other player that supports your file type.
  2. Convert video file format. Preferably change the video format to a widely supported file type, such as MOV and MP4. Use any online video converter, Stellar Converter for Audio Video, or VLC Media Player.
  3. Download the supporting codecs on Mac. You can try codec packs like Perian or K-Lite available for macOS.

If these workarounds don’t work, the video file might have corrupted. Repair it using a Mac video repair software shared in this post.

Conclusion

A free video repair tool such as VLC Media Player macOS version can fix file index corruption. However, a dedicated Mac video repair software, such as Stellar Repair for Video, ensures all kinds of damage in the video file is fixed.

It’s important to choose a 100% safe software for your sophisticated Mac system. Make sure it is capable of fixing your specific video problem. Not every video repair tool can fix severely damaged videos with sound issues or distorted visuals. So it’s advisable to use the free trial first. It will help to verify if the software can successfully repair your corrupt video on Mac.
