Problem
An archive preserves media but not the original timecode relationships between external recorder audio and camera files.
Solution
Root Cause / Diagnostic:
Multi-system production workflows rely on broadcast timecode (SMPTE LTC) embedded in Broadcast Wave Format (BWF) audio and camera metadata tracks for instantaneous synchronization. If archive consolidation strips native timecode tracks or converts audio to formats lacking timecode headers (e.g., standard MP3 or generic WAV), automated multi-track sync is broken.
Actionable Fix:
1. BWF Standard Preservation: Retain raw audio files in polyphonic Broadcast Wave Format (BWF) with embedded timestamp metadata intact; never convert or normalize audio prior to archiving.
2. Synchronized Sequence / Multicam Export: Export synchronized sequence XMLs and DaVinci Resolve timelines where audio and video are locked to matching timecode tracks.
3. Timecode Verification Check: Query restored audio and video files using `ffprobe` to confirm that `timecode` metadata tags match original slate timecode offsets.
Pro Tip:
Never convert production audio to basic WAV or MP3 files for archiving; keep polyphonic Broadcast WAV files with embedded timecode intact so your external sound syncs to camera video automatically.
