How to Repair Apple Pro-Res Video Files, Pro-Res, a video file format developed by Apple Inc., is essentially a compression software or codec that helps in encoding and decoding of a video while preserving its quality.
Pro-Res is mostly used in the post production phase, which includes extensive use of video editing applications.
Nowadays, many professional camera manufacturers have started to provide support for Pro-Res format files, which is a good news for Mac users as this takes the compatibility game to a whole new level.
But there’s a huge drawback here. The constant transfer of files from one device to another for post-production makes them prone to corruption.
Though all multimedia files are prone to corruption to some extent, Pro-Res files are exceptionally fragile. Even one damaged frame can make them inaccessible. But there’s nothing to worry.
By following this extensive step-by-step guide, you can easily repair your Apple Pro-Res files easily and efficiently.

Key Solutions for Repairing Apple Pro-Res Files
It’s actually pretty simple to repair Pro-Res files without compromising their quality. You can use the solutions described next for the purpose.
How to Change Device Name on Android
Solution 1: Use QuickTime Player
The major drawback of Pro-Res files is that if one frame is lost, the entire file would stop playing. QuickTime Player merely displays a Black Screen error after it identifies a significantly damaged file.
However, QuickTime player can automatically fix moderately damaged files that have only a few damaged frames.
All you need to do is open the file using QuickTime. It automatically starts its inbuilt repair process.
Note: While the QuickTime player has many options for editing, cutting, looping, storing, reversing, and repairing slightly damaged video files, it lacks advanced features required to restore seriously damaged video files.
Solution 2: Downgrade the Pro-Res Version
Pro-Res has two main versions – Pro-Res 422 and Pro-Res 4444. Both vary on the basis of video quality. Pro-Res 422 is the most compatible version and Pro-Res 4444 has the highest level of resolution.
Talking about the cons, Pro-Res 4444 isn’t compatible with some versions of QuickTime and other media players. Hence, it’s recommended to downgrade your version of the application if you’re facing errors with video playback.
You can do this by using the FF mpeg codec converter. FF mpeg is an open-source free software available for all operating systems including Mac.
Solution 3: Change the File Extension
Files encoded with the Pro-Res format have .MOV file extension. MOV was created by Apple and is compatible with QuickTime player.
But the same can’t be said about other media players. If the file is not playing in QuickTime, it’s time to change the file extension from MOV to MP4.
You can use VLC player to change the file extension as indicated below:
- Download the Mac version of VLC and launch it once the installation is complete.
- Navigate to the Media option from the top menu and select Convert/Save from the dropdown menu.
