Set timecode and genlock in Final Cut Camera
In Final Cut Camera, you can set the type or source of timecode to record in your videos.
With Final Cut Camera and iPhone 17 Pro or later, you can set the source of an external genlock signal to ensure perfect sync between multiple cameras and displays.
Set the timecode
Go to the Final Cut Camera app
on your iPhone or iPad.In the camera screen, tap
, tap Preferences, then tap Timecode.Tap an option:
Record Run: Counts up from the starting point (00:00:00:00) while the camera is actively recording and pauses when not recording. This timecode option shows the total recorded duration.
Time of Day: Runs continuously like a clock, whether recording or not. This timecode option shows the device clock time at which each frame was captured, making it easier to arrange clips in a timeline.
External Source: Receives timecode from an external generator or central device, making it easier to sync clips from different cameras in post-production. This option is available when you connect an external timecode generator to your iPhone with a USB-C cable. Tap
next to Source, then tap the name of the device.The color of the icon next to the device name shows its current status: green for Synchronized, dotted green for Jam Synced, and red for Error.

Set a genlock source
With Final Cut Camera and iPhone 17 Pro or later, you can set the source of an external genlock signal, which synchronizes the video timing of multiple cameras and compatible video displays and allows their frames to be generated in phase.
You can also set a genlock frame delay to compensate for timing differences with a genlocked display or latency differences between your iPhone and other genlocked cameras. A frame delay lets you offset when the camera shutter is triggered relative to the external genlock signal.
Note: Setting a genlock source requires iPhone 17 Pro or later.
Go to the Final Cut Camera app
on your iPhone.In the camera screen, tap
, tap Preferences, then tap Genlock.Connect a compatible sync generator device to your iPhone.
The name of the genlock device appears below Genlock. The color of the icon next to the device name shows its current status: green for Synchronized, dotted green for Jam Synced, and white for Out of Sync.
To adjust the genlock frame delay, tap Adjust Genlock Offset, then drag the slider while previewing the video.
If you want to change the units of offset, tap
, then choose an option:Subframes: A subframe has 1/100 the duration of a video frame, so a subframe’s duration in real time depends on the frame rate.
Microseconds: A microsecond is an absolute unit of time: 1/1,000,000 of a second.
