Documentation of Proceedings and Post-Production Deliverables
The log and the untouched original
Documentation is what makes the video usable. Keep a contemporaneous log: convening time, oath, appearances, every start and stop with time-stamp readings, objections and rulings, exhibit numbers as marked, breaks, and adjournment. Note who is speaking when more than one person is off camera. The log is your defense if a question later arises about a gap or an off-record discussion.
Post-production for legal video is deliberately minimal. You may convert formats, correct sync drift, and produce a synchronized copy aligned to the transcript; you may not cut, reorder, sweeten, or otherwise alter content. Preserve the original file untouched, verify it plays end to end, and generate a hash or checksum if your workflow uses one. Label media with matter, date, camera, and audio source, and deliver in the format the noticing party specified - commonly MP4/H.264 for review plus a higher-quality master for archive.
Chain of custody matters: log who received each copy and when, keep working and archive copies in separate locations, and retain media per the agreement or applicable rules rather than deleting it once the invoice is paid.
Traps: delivering only one copy, delivering a file the recipient's software cannot play, failing to log off-record periods so the transcript appears to skip, and "cleaning up" audio. Any question that frames editing content as a convenience has a wrong answer.
Rule of thumb: never destroy or overwrite an original; duplicate first, then convert.
