Syncing Multicam Documentary Interviews on a Budget: Tentacle Workflow in Resolve
Perfect audio sync every time. Learn the budget-friendly Tentacle Sync workflow for syncing multicam documentary interviews flawlessly in DaVinci Resolve.
How do you sync multicam documentary interviews in DaVinci Resolve using Tentacle Sync?
To sync multicam footage, attach Tentacle Sync timecode generators to all cameras and audio recorders, import the footage into DaVinci Resolve, select all clips, right-click, and choose "Update Timecode from Audio Track," then create a Multicam Clip based on Timecode.
Shooting a documentary interview with three cameras (e.g., a wide shot, a tight shot, and a profile shot) plus a dedicated external audio recorder creates a massive syncing headache in post-production. Relying on a traditional slate or "clapping" means the editor must manually align four different tracks for every single take, which wastes hours. Tentacle Sync devices are budget-friendly timecode generators. You plug one into the microphone port of each camera. Instead of recording actual audio, the Tentacle records a high-pitched, robotic screech (LTC timecode) onto the audio track. DaVinci Resolve is specifically designed to read this screech. By selecting all the clips and telling Resolve to update the timecode based on that audio track, every piece of media instantly shares a mathematically perfect, frame-accurate timecode. You then click "Create Multicam Clip Using Timecode," and the entire interview is synced in three seconds.
Why is audio timecode (LTC) necessary for DSLR and mirrorless cameras?
Audio timecode is necessary because most consumer DSLR and mirrorless cameras (like the Sony A7IV or Canon R5) lack dedicated professional timecode input ports, forcing you to record the timecode signal directly onto the standard 3.5mm microphone audio track.
High-end cinema cameras like the ARRI Alexa have dedicated BNC ports that accept timecode signals natively, embedding the data directly into the video file's metadata. Consumer cameras do not have this hardware. To bypass this limitation, Tentacle Sync outputs the timecode data as an audible sound (Linear Timecode, or LTC). When you plug the Tentacle into the camera's 3.5mm mic jack, the camera records this sound just like it would record a person speaking. Professional NLEs like DaVinci Resolve are programmed to listen to that specific audio track, translate the screech back into digital metadata, and sync the clips perfectly.
How should editors share synced multicam sequences for director approval?
Editors should export a split-screen version of the synced multicam sequence and upload it to Cutsio, providing a white-labeled presentation layer where the director can verify the sync and camera angles securely.
Before the actual editing begins, the director often needs to verify that the multicam setup was successful and that all angles look correct. Sending a massive video file via a generic cloud drive will result in buffering and poor playback. By uploading the multicam sequence to Cutsio, the editor provides a frictionless review experience. The director receives a secure, branded link with high-fidelity playback. They can leave frame-accurate comments, and the editor can rely on Cutsio’s approval gates to secure sign-off on the synced media before beginning the rough cut.

FAQ
Do I need the Tentacle Sync Studio software to sync in DaVinci Resolve?
No, while Tentacle provides their own standalone syncing software, DaVinci Resolve Studio natively reads audio timecode (LTC) directly on the timeline, eliminating the need for third-party software.
Will the timecode screech ruin my interview audio?
No, the timecode screech is only recorded on the camera's internal "scratch" audio track. Your high-quality interview audio is recorded safely on your dedicated external audio recorder.
Can I sync footage in DaVinci Resolve without timecode?
Yes, DaVinci Resolve has an "Auto Sync Audio Based on Waveform" feature. It analyzes the actual spoken words on the camera and the external recorder and attempts to match them, though it is slower and less reliable than timecode.
