Do one of the following:

• Select one or more projects or clips in the browser.

  Note: You can’t mix projects and clips in a batch share. Your selection must contain only projects or only clips. For more information, see About batch sharing.

• 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.

• Select one or more ranges in clips in the browser.

  For information about selecting multiple ranges, see Manage multiple range selections in event clips.

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.

Do one of the following:

• Choose File > Share > Master File (or press Command-E).

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

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

• Move the pointer over the image to skim the video.

  If you’re batch sharing (exporting multiple items), the image is replaced by a list of the items you’re exporting.

• 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.

Click Settings at the top of the Share window.

In the Settings pane, click the Format pop-up menu and choose MXF.

Click the “Video codec” pop-up menu and choose a video codec for the MXF file.

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

Click Roles at the top of the Share window.

In the Roles pane, click the “Roles as” pop-up menu and choose one of the following:

• Multitrack MXF File (the default setting)

• A custom preset

  For information about creating a custom preset, see Create and modify custom presets.

The default Multitrack MXF File setting presents a list of tracks (including a video track, a track for each audio subrole assignment, and a caption track).

Do any of the following:

• Combine roles in a track: For any track in the list, click the Add Role pop-up menu (on the right) to add roles or subroles for the track.

• Remove roles from a track: For any role, click the Remove button (on the right).

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

• Add an audio track to the export file: Click the 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: Click the Remove button (with an X) to the right of the track name.

• Burn captions in to the output video file: For each video track or file, click the blue Captions button, then click the “Burn in captions” pop-up menu and choose a language version.

• Add captions to the export: In the Captions section, select the caption formats you want to export, then click the Timing pop-up menu and choose an option:

  • Relative: Calculate the caption start time by subtracting the project’s start time.

  • Absolute: Use each caption’s actual start time, regardless of the project’s start time.

  Final Cut Pro will create a separate “sidecar” caption file for each language subrole in the selected caption formats and place the files in the same folder as the exported MXF file.

  For information about adding captions to your project, see Captions overview and Create captions.

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

Click Next, choose a location for the exported files, then click Save.
