Export options
The Export menu has two checkboxes. Both change only the exported file; your files on disk stay as they were.
Matching timecode
In the export every camera gets the same timecode that follows from the sync, instead of its own free-running one. In Premiere Pro a multicam sequence then assembles by timecode with no fixing at all.
- Applies to Premiere Pro only. For DaVinci Resolve and Final Cut Pro the checkbox is skipped with a message, because those editors look for media by the file's timecode and would get everything offline.
- The choice is remembered between launches.
Split channels to mono
Every audio channel becomes its own mono track: L and R for stereo, 2, 3… for multichannel recorders. Camera sound stays linked to its video. The change is visible on the timeline right away, before the export.
- The checkbox is off on every launch.
- The channels of one recorder move between tracks together, as one track.
Unplaced clips in shooting order
This is not a checkbox in the menu but a switch above the timeline, and it changes the export too: what goes into the file is what is on screen. See Clips without proof.
