As part of the transition from 32-bit to 64-bit technology in macOS, you might see an alert in Final Cut Pro or Motion about legacy media files that won't be compatible with macOS Catalina.
Before you upgrade to macOS Catalina, you can use Final Cut Pro to detect and convert all incompatible media files so they'll be compatible with future versions of macOS. After you upgrade to macOS Catalina, the option to convert the incompatible files will no longer be available.
When trying to play incompatible media in macOS Catalina, you might see an incompatible media message in the viewer if you haven't converted the media before upgrading to macOS Catalina.
Detect and convert incompatible media files in Final Cut Pro in macOS Mojave
When you import media or open a library in Final Cut Pro 10.4.7 or later in macOS Mojave 10.14.6, a window appears that lists any incompatible media files.
To convert incompatible media files immediately, click Convert in the window. Final Cut Pro creates copies of the media files in the Apple ProRes format, places them in the library’s current media storage location, and relinks clips in the library to the converted files.
If you choose Cancel, you can resume scanning the library and convert the incompatible files at any time in macOS Mojave:
- In Final Cut Pro, choose File > Check Media for Compatibility.
- In the window listing incompatible media files, click Convert.
Learn more about how Final Cut Pro detects and converts incompatible media files.
Manually identify the format of clips
You can also use Final Cut Pro to manually identify the format or codec of any clip in your library:
- If the browser is not already in list view, click in the top-right corner of the browser, or choose View > Browser > Toggle Filmstrip/List View.
- Control-click any column heading in the browser, then choose Codecs in the list.
- Scroll the browser left or right to see the Codecs column.
- To sort clips by codec, click the Codecs column heading.
If you created optimized media
When you create optimized media, Final Cut Pro makes copies of the original files in the Apple ProRes 422 format. These copies will be compatible with macOS Catalina. If you created optimized media, you should still convert the original files for future compatibility. When you convert the files, they will be in the same ProRes 422 format as the optimized media.
If your Final Cut Pro library contains Motion projects with incompatible media files
Final Cut Pro won't detect incompatible media used in Motion projects. To see if a Motion project uses incompatible Media, open it in Motion. A message will appear if incompatible media is detected. If incompatible media is present, you can use QuickTime Player or Compressor to convert incompatible media in the Motion project in macOS Mojave.
Convert incompatible media in Compressor
Convert incompatible media in QuickTime Player
You can also convert incompatible media files in macOS Mojave by opening them with QuickTime Player (version 10.0 and later), then saving a copy with a new name. Versions of macOS after macOS Mojave will no longer support this method.
In macOS Catalina, you can't convert incompatible media with QuickTime Player.
Formats compatible with macOS Catalina
These video, audio, still-image, and container formats don't rely on the QuickTime 7 framework, and are compatible with Final Cut Pro, Motion, and Compressor in macOS Catalina:
- Apple Animation codec
- Apple Intermediate codec
- Apple ProRes
- Apple ProRes RAW
- AVCHD (including AVCCAM, AVCHD Lite, and NXCAM)
- AVC-ULTRA (including AVC-LongG, AVC-Intra Class 50/100/200/4:4:4, and AVC-Intra LT)
- Canon Cinema RAW Light2
- DV (including DVCAM, DVCPRO, and DVCPRO50)
- DVCPRO HD
- HEVC (H.265)
- Motion JPEG (OpenDML only)
- MPEG-4 SP
- MPEG IMX (D-10)

- Uncompressed 10-bit "R10k"
- XAVC (including XAVC-S)
- XDCAM HD/EX/HD422
- MOV (QuickTime)
2 These formats are supported in Final Cut Pro and require additional software from the camera manufacturers.
Media formats affected by the transition to 64-bit technology
In macOS versions up to and including macOS Mojave, third-party software has extended the QuickTime 7 framework to support many incompatible media formats. In macOS Catalina, the QuickTime 7 framework will no longer be available, so incompatible formats won't be supported in Final Cut Pro, Motion and Compressor.
Third-party developers may continue to offer compatibility with some formats by building support directly into their apps. Contact developers of third-party apps for more information about media formats supported in their apps.
Here are examples of media formats affected by this transition:
- 3ivx MPEG-4
- AV1 / VP9
- AVC0 Media AVA0 Media
- Avid DNxHD / DNxHR
- Avid DV / DV100 / JFIF / Motion JPEG
