Export an AAF from Final Cut Pro,
step by step.

Final Cut Pro cannot write an AAF. It writes FCPXML, which a converter turns into a session Pro Tools can open. Six steps, and the two that matter happen before you export anything.

Final Cut Pro 10.4 to 12.3 · FCPXML up to 1.14 · macOS 11+

1. Tidy your roles first — this is the whole job

Everything downstream depends on this step, and it is the one people skip.

Open the Index, go to the Roles tab. Every clip should sit in a role that means something to the sound department: dialogue, effects, music, plus named subroles for each interview, location or speaker.

Roles are what become named tracks in Pro Tools. A clip left in the default role arrives anonymous, and the mixer starts by sorting instead of mixing. Ten minutes spent here saves an hour at the other end.

A practical habit: name subroles after what they are, not where they came from. ITV KITCHEN tells a mixer more than CAM B.

2. Switch off the audio you do not want to send

Reference masters laid on the timeline, temp music, takes you muted — anything whose sound must not travel. Select the clip and disable its audio.

What is disabled in the edit stays out of the AAF. On one real episode this removed a full programme master that would otherwise have poured twenty-six minutes of finished mix into the session.

3. Export the XML

Select the project in the browser, then File > Export XML. Keep the default metadata setting.

Final Cut Pro 11 and 12 write a .fcpxmld bundle — macOS shows it as one item but it is a folder. Older versions write a single .fcpxml file. Both work; you never need to open the bundle.

4. Drop it on AAFx and actually read the report

This is your last chance to catch a problem cheaply.

AAFx reporting on an FCPXML before conversion: clips found, roles turned into tracks, multicam resolved, disabled clips excluded, media reachable

Check three things before clicking anything:

5. Choose your handles

Handles are the audio kept before and after each cut, so the sound editor can rebuild a transition without asking you for the rushes.

Two seconds is right for a fast-cut magazine. Ten to thirty seconds suits drama, where transitions get reworked. The file grows in proportion — AAFx shows the estimate past ten seconds, so you know before you commit.

When in doubt, ask the person receiving it. It is the one question sound editors always have an opinion about.

6. Import in Pro Tools

File > Import > Session Data, select the AAF, and choose to import all tracks. The session opens with named tracks, each region at its timeline position, carrying the source timecode of its own rush.

Nothing is offline: the audio essence travels inside the AAF.
