Deposition video: sync, timecode burn-in and a checksummed delivery manifest
If you shoot depositions, the job after the shoot is the same every time: line up the cameras, put the timecode on the picture, and hand over files you can show are the files you made. Throughline does those steps on your Mac, and nothing is uploaded.

Sync the cameras and the audio
Throughline aligns your cameras and any separate audio recorder to one timeline from the sound, with no slate and no timecode required. It copes with recordings that span several files and with mixed frame rates. Each offset carries a confidence score, and a low-confidence match is flagged for review rather than accepted.
Burn in the date, timecode and elapsed time
The deposition burn-in draws the date, timecode and elapsed seconds onto the picture, and writes a matching .srt sidecar. If it could not draw something, it tells you in an explicit report instead of quietly leaving it out. Burn-in is optional and set per export, so your clean masters stay clean.
Place the certified page:line
Give it the court reporter’s certified transcript and Throughline places its page:line references against the recording, so you can cite 14:3 and land on the moment it was said. A line it cannot place is reported as unplaced. It is never guessed or interpolated.
Deliver with a checksummed manifest
Cards are copied to one or more destinations and checked as they are copied, with an ASC MHL manifest. At delivery, Throughline writes a checksummed manifest recording what each step touched, what it preserved and what it invalidated, with your sign-off recorded against it. You can add an RFC-3161 timestamp. It is available, and off by default.
Private by default
Transcription and speaker identification run on your Mac. A deposition transcript can be privileged, so sending a transcript to anything off the machine requires explicit consent, recorded per provider.
Honest limits
- The manifest is not cryptographically signed. It is a checksummed record with your sign-off recorded against it. The RFC-3161 timestamp is optional and off until you turn it on.
- It is not legal advice. Requirements for exhibits and video records differ by court and jurisdiction. Confirm what yours asks for.
- It does not replace the reporter’s record. Page:line placement follows the certified transcript you provide.
- Mac only. macOS 14 or later, Apple silicon.
Try it on a real deposition
The 14-day free trial runs every feature on your own footage, twice, with no card. Trial exports cover the first 60 seconds, and video it writes is a 720p proof with an overlay, which is enough to check the burn-in and the manifest against what your clients expect.

Questions
What does the deposition burn-in put on the picture?
The date, timecode and elapsed seconds, with a matching .srt sidecar. It also reports anything it could not draw.
Is the delivery manifest cryptographically signed?
No. It is a checksummed manifest with your sign-off recorded against it. An RFC-3161 timestamp is available and off by default.
Does a deposition transcript leave my Mac?
Not by default. Transcription runs on your machine, and sending a transcript to anything off the machine requires explicit consent, recorded per provider.
What happens to a page:line it cannot place?
It is reported as unplaced. Throughline does not interpolate or guess.
