What are multicam recordings
Multicam means recording the same scene with multiple cameras in parallel. You save retakes, get more coverage for editing and achieve dynamic perspective changes with minimal effort. Typical use cases are interviews with two angles, bike and action setups with helmet and handlebar cams, events where you cover stage and audience, or vlogs where a Pocket camera captures the host while Action cams deliver B-roll.
How multicam sync works
To align clips perfectly in the timeline you need a common reference. In practice three methods are proven.
1) Simultaneous start
Start all cameras as closely together as possible. This is simple and ideal for short takes. Small offsets are easy to nudge by eye in the timeline. For long takes or many cameras add one of the sync methods below.
2) Waveform or audio sync
Create a sharp audio peak at the start – a hand clap, beep or short call. NLEs like DaVinci Resolve, Adobe Premiere Pro or Final Cut can align clips automatically by matching the audio waveforms. For very long takes repeat a clap in the middle to guard against minor drift.
3) Timecode
The pro method. A running timecode is provided by a generator and sent to the cameras or generated inside them. Clips then line up frame accurately. Depending on the model this works via USB-C or as LTC recorded on an audio channel. Timecode shines for long interviews, concerts, documentaries or whenever audio is recorded separately.
Multicam with DJI Osmo cameras
DJI covers several device classes that combine nicely in multicam sets.
- Osmo Action 4 and 5 – rugged action cams with strong stabilization. Ideal for POV, sports, vehicles and B-roll.
- Osmo 360 – 360-degree camera for reframing in post. One camera, many angles.
- Osmo Pocket 3 – compact gimbal camera with great handling for hosting, interviews and smooth moves.
- Osmo Nano – released in 2025, ultra compact and lightweight. Perfect as an extra angle where size and weight are critical, for unusual mounting points or as a discreet B-cam.
Simultaneous start with the Osmo Action GPS Bluetooth Remote
The DJI Osmo Action GPS Bluetooth Remote pairs via Bluetooth with multiple Osmo Action cameras and can start and stop them together. It is practical on the bike, on a gimbal grip or on your wrist – one press starts all paired Action cams, another stops them. The remote also records GPS data that you can overlay later in the DJI app as speed, route, direction and elevation.
Timecode with Pocket and Action – plus LTC as fallback
- Pocket 3 and the Action 5 Pro support timecode workflows via USB-C. Jam them once from a generator and they run in sync for the day.
- LTC as audio track is the universal plan when a body has no native timecode. A tiny box feeds an LTC signal into one audio channel. Your NLE reads the LTC back and aligns the clips.
Waveform sync remains the reliable plan B
Even if you run timecode, a quick clap at the start is worth it. It gives you a visible and audible mark in the timeline and saves the day if one camera did not jam properly or if timecode is limited at high frame rates. This method also works great when mixing brands where not all cameras support timecode and when sound is captured on a separate recorder.
Which cameras work with the Osmo Action GPS Bluetooth Remote
The remote is designed for the DJI Osmo Action series and supports multicam start and stop with multiple Action bodies. This includes DJI Osmo Action 4 and DJI Osmo Action 5 Pro. DJI Osmo 360 can run in parallel within a multicam set and can be triggered via the remote when Bluetooth pairing is active. DJI Osmo Nano also connects via Bluetooth. DJI Pocket 3 uses its own remote options and is not compatible with the Bluetooth remote, so in multicam it is synced via timecode or waveform. Always check the current firmware compatibility of your devices.
Technical data – Osmo Action GPS Bluetooth Remote
- Range – reliable wireless triggering at typical on-set distances outdoors, indoors depending on surroundings
- Number of cameras – multicam triggering for several Osmo Action cameras at once with up to 16 cameras
- Pairing – Bluetooth Low Energy
- Position – GPS logging for overlays like speed, route, heading and altitude
- Protection – splash resistant for outdoor use
Note: radio range and maximum camera count depend on firmware, environment and pairing status. Always test before critical shoots.
Alternatives and useful add-ons
- External timecode generators – ideal for Pocket 3 and Action 5. Jam once and forget for the whole day.
- LTC box on the audio channel – universal when a body lacks native timecode.
- DJI Mic as audio solution – clean backup audio and a clear peak for waveform sync.
- Smartphone app – great for controlling single cameras. For true multicam starting, the Bluetooth remote is more efficient.
- Gyro data and 360 reframing – the combo of Action cam and 360 covers rides and dynamic motion beautifully. Gyro data gives you extra stabilization options in post.
Practical tips for stable results
- Keep the 180-degree shutter rule, carry ND filters.
- Use a fixed white balance instead of auto to avoid color jumps between angles.
- Match audio settings across cameras, check levels, set wind filters consciously.
- Shorter takes with gaps simplify backups and reduce file errors. After each pause add a new clap for waveform sync.
- Secure cables and mounts, especially with LTC boxes or external mics.
- Always clap as backup, even when running timecode.
FAQ
How do I start multiple Osmo Action cameras at once
Use the Osmo Action GPS Bluetooth Remote. Pair, test, then start and stop all cameras in parallel.
Is multicam only possible with timecode
No. Waveform sync works great and is often faster to set up. Timecode pays off when you have long takes or many cameras, but may require extra hardware depending on the model.
Can I combine Pocket 3 with Action cams
Yes. Pocket 3 as A-cam for hosting, Action cams as B-roll. Sync via timecode or waveform. Start them separately or use the remote for the Action bodies.
How do I integrate the Osmo Nano
Use it as a discreet extra angle. Start over Bluetooth and sync via waveform or the timecode workflow depending on your setup.
What is GPS in the remote good for
To overlay speed, route, heading or elevation. Popular for bike videos, road trips and running challenges.

- A-Roll – primary footage that carries the story or speaker.
- ATC – audio timecode recorded on an audio channel.
- B-Roll – supporting footage that adds context, details, cutaways and flow.
- Bitrate – data per second in video or audio. Higher bitrate preserves detail and motion.
- Clap – hand clap or beep at the start of a take to create a peak for waveform sync.
- D-Log M – DJI log profile with flat contrast and wide dynamic range. Requires conversion or a LUT.
- Framerate – frames per second such as 24p, 25p, 30p, 50p, 60p. Should match across cameras.
- Genlock – hardware sync of video timing between cameras. Common in studio cameras, rare in action cams.
- GNSS – satellite navigation like GPS, Galileo, BeiDou, GLONASS. Used for telemetry overlays.
- Headroom – safety margin in audio above the average level to capture peaks cleanly.
- Intra-frame – each frame encoded independently, for example ProRes. Edit friendly for multicam.
- Jam-sync – one device provides timecode, others take over and keep running in sync.
- Line level vs mic level – line is hotter for device outputs, mic is lower for microphones. Wrong level causes noise or distortion.
- LTC – linear timecode as an analog audio signal that can be read by the NLE.
- LUT – lookup table for fast color transforms, for example Log to Rec.709.
