One event, four cameras, a single timeline
The same traffic stop exists three times: the officer's bodycam, the dashcam, and the security camera across the street — plus the interview-room recording back at the station. Evidence Copilot links them to one master clock so you can see the event once, with an interleaved transcript, instead of scrubbing four players.

Separate players hide the story
Reconstructing one event from four unsynchronized videos means eyeballing clocks that were never set to each other and audio that overlaps unpredictably.
The moments that matter — who said what while the camera was angled away — only show up when the cameras are locked together.
How it works
- 1
Group the files
Link two or more processed recordings of the same event into a sync group.
- 2
Mark a reference moment
Scrub each video to the same real-world instant and mark it — or accept an automatic proposal.
- 3
Review the proposal
Auto-sync cross-correlates word timings across transcripts and proposes reference moments with confidence and match evidence — e.g. '31 word matches, ±0.2 s spread'. Proposals are never auto-applied.
- 4
Play it locked
One master clock drives every pane with offset badges; the interleaved transcript clicks through to all cameras at once.
What you get
Synced playback
A single master clock, muted members when you want one audio source, and auto-correction to keep drift within a fraction of a second.
Interleaved transcript
All speakers across all cameras in one chronological transcript on the master clock.
Evidence-based auto-sync
Proposals report their evidence — word-match counts and timing spread — and wait for your confirmation.
Frame and clip from the group
Grab frames or extract clips from any member while the group stays in sync.

- Attorneys reconstructing stops and arrests
- Investigators comparing camera angles
- Firms preparing synchronized trial exhibits
Frequently asked questions
How does automatic multi-camera sync work?
The recordings' transcripts carry word-level timestamps. Cross-correlating those timings across videos produces candidate alignments with measurable evidence — how many words matched and how tightly. You review the proposal and confirm; nothing is ever applied to your case without you.
What if the cameras have no overlapping audio?
Manual reference marking always works: scrub each video to the same real-world moment and mark it. Auto-sync is a shortcut when audio overlaps, not a requirement.
Can I export a synchronized clip?
Clips extracted from a sync group carry their offsets, so the exported segments stay aligned to each other in your exhibit pack.
