To sync two cameras in ChatCut, import recordings of the same take with overlapping, recognizable audio, select them, and choose AI multicam sync. Check the aligned tracks at several shared events before cutting between angles. As of October 28, 2026, the documented command aligns clips; speaker-follow editing is a separate task that needs its own review.
Verified controls and evidence
Last verified: 2026-10-28. These are documented controls and a review method. No matching two-camera/recorder export test was performed for this guide; synchronization accuracy, drift correction and editing quality have not been measured here.
| Scope | Verified boundary | Source checked 2026-10-28 |
|---|---|---|
| Editor control | My Assets and Timeline offer AI multicam sync for at least two recordings; existing Timeline clips must be at 1× speed. | Timeline reference |
| Alignment result | Clips stay on ordinary tracks. A missing confident audio match leaves the selection unsynchronized; same-track overlap can also prevent a change. | Timeline reference |
| Agent method | The published workflow uses a reference source and reports measured placement evidence. Its default can include speaker-follow editing; explicitly request sync only when that is your goal. | Published multicam workflow |
| Model and route | This is an editing workflow, not a promise about a video-generation model. A listed skill does not prove every connected host exposes the same tools. | Published workflow, Agent Plugin |
Prepare cameras, recorders and overlap
Use files from the same recorded event. Keep camera audio even when a separate recorder will supply the final sound: that shared audio helps establish timing. Distinguish simultaneous angles from sequential files created when one camera stops and restarts. Filenames alone cannot establish this relationship.
Choose a clear, long reference recording when available. Locate several shared claps, words or other recognizable events across the actual overlap. A short noisy fragment may not provide enough evidence; an unrelated recording cannot be synchronized simply by choosing the same command.
Align in the editor
- Create a separate review timeline so the current edit remains available.
- In My Assets, Command/Ctrl-click at least two video-with-audio or audio cards. Right-click a selected card and choose AI multicam sync.
- The usable clips are placed on separate tracks at the playhead. Wait for Preparing AI multicam sync and its progress indication to finish.
- Alternatively, select at least two clips already on the Timeline, check that their playback speed is 1×, and use the same right-click command.
- Inspect the resulting positions and play a shared clap or spoken phrase with sound. The command does not cut between angles.
For an Agent request, use ChatCut’s built-in AI panel, or connect an external host first. For local packages, select the project through the Desktop workflow. Do not assume a built-in Agent result verifies the external-host path.
Sync only: inspect these recordings from one session and identify simultaneous camera angles, recorder audio and sequential camera files. Build a separate synced review timeline without changing my current edit. Use a clear reference, report the offsets and evidence for each clip, and leave uncertain matches unresolved. Preserve actual recording gaps. Check shared events near the beginning and end. Do not switch angles or time-stretch clips.
Review offsets, gaps and drift
An offset is the difference between a clip’s timeline position and its source time. For example, if source time 0 is placed at timeline time 5 seconds, the offset is +5 seconds. Keep the placement of each clip consistent when later cutting excerpts from it.
Check the beginning, middle and end of the shared recording interval. If an early event aligns but a late event does not, record the discrepancy before changing speed; clock differences, dropped frames or a wrong match need different treatment. This guide does not establish automatic drift repair.
Preserve a verified stop/start gap in the recording. For files known to be consecutive uninterrupted spans, an unexpected gap or overlap is a reason to recheck the match. Do not trim away evidence just to make adjacent files appear continuous. Label missing coverage so it cannot be mistaken for a failed camera switch.
Recover an uncertain match
| Observation | Next step |
|---|---|
| No confident match | Check that the files overlap in time and contain recognizable shared sound. Keep the original clips and report the unresolved file. |
| Same-track overlap blocks alignment | Put the affected clips on separate tracks, then retry that selection. |
| A short or noisy clip is uncertain | Find clearer shared events or request an evidence-backed transcript comparison. Review any manual placement; do not label it automatically verified. |
| Early and late events disagree | Recheck the source and reference; report the measured difference before deciding on a timing repair. |
| The external host lacks the tool | Check its connection and session, or use the documented editor command. Do not repeat a request indefinitely. |
Cut angles and deliver
After reviewing the synced master, request an angle edit on a separate timeline. Specify the desired excerpt and program audio, then review speaker identification, reaction shots, coverage gaps and speech joins. Keep the synced master as the timing reference.
Export the selected edit through the Export Panel, then check the delivered file at the same early and late events. An aligned timeline or completed render alone does not prove the exported audio stays in sync. Current charges are owned by the credits policy; failures and pending operations are covered by workflow recovery.
