Import third-party formats with media extensions in Compressor
The Media Extensions feature built into macOS lets you use third-party media formats that aren’t natively supported in Compressor.
Note: The Media Extensions feature requires macOS Sequoia or later.
Install and turn on media extensions for third-party media formats
Download and install the media extension for the third-party media format you want to use.
Choose Apple menu
Click General in the sidebar, then click Login Items & Extensions.
In the Extensions section, click By Category (if available), then click the Info button next to Media Extensions.
Turn on any format readers, decoders, or processors for the media extension you installed (you may need to scroll down), then click Done.
Quit Compressor (if it’s open), then reopen Compressor.
You can now work with video encoded in that third-party media format.
Note: After turning on a third-party RAW processing plug-in, you can adjust RAW processing parameters.
View the status of media extensions in the Job inspector
Import a video source file that’s encoded in a third-party media format.
A new job appears in the batch area.
Select the job to view its properties in the Job inspector.
The Media Extensions section of the Job inspector displays any media extensions that are required to decode media in the selected job.
A green dot indicates that the media extension is being used to decode the selected source media. If a red triangle appears next to the media extension, there’s an issue. Click the Extension Settings button to open the Extensions section in System Settings and resolve the issue.
After you import source media, you can view and modify job properties, apply transcoding instructions, and transcode the batch.
