Final Cut Pro X: Export an MXF file

Export an MXF file

MXF is an industry-standard file format for video and audio. Like QuickTime files, MXF files contain information about the media inside. This information, also called metadata, can include frame rate, frame size, creation date, and custom data added by a camera operator, an assistant, or an archivist.

When you export MXF master files, you can use audio roles to configure industry-standard channel layouts.

  1. Do one of the following:

    • Select a project or a clip in the browser.

    • Select a range in a project in the timeline or in a clip in the browser.

      Note: To share just a portion of a project, you must make a range selection. A clip selection is not sufficient. You can use the I and O keys to set the range start and end points.

  2. If you’re sharing a project that is set to use proxy media for playback, open it in the timeline, then click the View pop-up menu in the top-right corner of the viewer and choose Optimized/Original.

    This ensures the highest quality in the exported file. When you choose this setting, Final Cut Pro uses optimized media to create the shared file. If optimized media doesn’t exist, the original media is used. For more information about optimized and proxy media, see Control playback quality and performance.

  3. Do one of the following:

    • Choose File > Share > Master File.

    • Click the Share button in the toolbar, then click Master File.

      The Share button in the toolbar
    • Press Command-E.

  4. In the Share window that appears, do any of the following:

    The Info pane of the Share window for the Master File destination
    • Move the pointer over the image to skim the video.

    • In the Info pane, view and modify project or clip attributes, such as the title and description.

      For more information, see View and change metadata shared with projects. All of the attributes associated with the project or clip are included in the output file.

      Important: By default, the title field lists the project or clip name. Changing the title does not change the project or clip name, which is the name used for the exported file.

    • At the bottom of the window, view information about the file that will be exported, including frame size and frame rate, audio channels and sample rate, duration, output file type, and file size.

      For some destinations, you can also view a list of devices that will play the exported file. To view the compatible devices, move the pointer over the Compatibility icon in the lower-right corner.

  5. Click Settings.

  6. Click the Format pop-up menu and and choose MXF.

  7. In the window that appears, click the “Video codec” pop-up menu and choose a video codec for the MXF file.

    Note: The available video codecs are determined by the resolution and frame rate of your project.

  8. Click the “Roles as” pop-up menu and choose one of the following:

    The default Multitrack MXF File setting presents a list of tracks (a Video/Titles track as well as one track for each audio subrole assignment).

  9. Do any of the following:

    • Combine roles in a track: For any track in the list, click the role pop-up menu (on the left) to add and remove roles or subroles for the track.

    • Choose an audio channel format for a track: For any audio track in the list, click the pop-up menu on the right and choose the channel format (Mono, Stereo, or Surround). For more information, see Configure audio channels.

    • Add a track to the export file: Click the Add Video Track or Add Audio Track button, then choose a role or subrole and an audio channel format from the pop-up menus that appear.

    • Remove a track from the export file: Move the pointer over the role you want to remove, then click the Remove button (–) that appears on the far right.

    • Save a preset: Click the “Roles as” pop-up menu and choose Save As in the Presets section.

  10. Click Next, choose a location for the saved file, then click Save.

You can monitor the progress of the transcode in the Background Tasks window, and you can continue to work in Final Cut Pro while the file is transcoded.

When transcoding is complete, a notification appears. You can view and locate shared projects in the Share inspector. For more information, see View the status of shared projects.
