About incompatible media in Final Cut Pro

Detect and convert incompatible media in Final Cut Pro in macOS Mojave.

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 or later.

Before you upgrade to macOS Catalina or later, 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 or later, the option to convert the incompatible files will no longer be available.

To make sure any new media files you create are compatible with macOS Catalina or later, use cameras and media formats supported by Final Cut Pro, and use media formats supported by Motion.

When trying to play incompatible media in macOS Catalina or later, you might see an incompatible media message in the viewer if you haven't converted the media before upgrading to macOS Catalina or later.

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:

  1. In Final Cut Pro, choose File > Check Media for Compatibility.

  2. In the window listing incompatible media files, click Convert.

Learn more about how Final Cut Pro detects and converts incompatible media files.

To convert incompatible media files detected in Motion and Compressor in macOS Mojave, use QuickTime Player to convert single files, or use Compressor to convert multiple files at once.

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:

  1. If the browser is not already in list view, click the Toggle Filmstrip/List View buttonList View button in the top-right corner of the browser, or choose View > Browser > Toggle Filmstrip/List View.

  2. Control-click any column heading in the browser, then choose Codecs in the list.

  3. Scroll the browser left or right to see the Codecs column.

  4. 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 or later 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

In macOS Mojave, you can use Compressor to transcode one or more media files into a supported format such as Apple ProRes, which preserves image quality and provides the best performance when editing in Final Cut Pro.

In macOS Catalina or later, you can't convert incompatible media with 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 or later, you can't convert incompatible media with QuickTime Player.

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 or later, 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
