Final Cut Pro allows you to modify the timecode of source clips or to add auxiliary timecode tracks, specifically Aux 1 and Aux 2. This is useful for multi-camera editing.

Smoke supports only one timecode track, so it is best to avoid using multiple timecodes in Final Cut Pro or to remove the auxiliary timecode tracks before exporting.

Removing additional timecode tracks involves a process that must be performed on each file to be exported.

To remove additional timecode tracks in a clip:

1. In Final Cut Pro, select the clip.
2. Choose Modify | Timecode.
3. Disable Aux 1 and Aux 2.
4. Repeat for every clip for which you want to remove additional timecode tracks.
