How do you coordinate video, narration, and captions in one pipeline?

A complete media pipeline must produce related artifacts, not just three independently successful files. The video, narration, and captions should describe the same approved content.

Use shared input identity

Tie the job to a reviewed script version and record the versions of generated audio and visual assets. Derive caption timing from the narration that will actually be used. Keep a manifest of the inputs chosen for final assembly so later diagnosis can reconstruct the result.

Validate the combined output

Check that the intended narration is audible, captions match the speech, and visuals follow the planned timeline. A caption file generated before an audio revision may be technically valid but incorrect. Exercise one edit-and-regenerate flow to verify invalidation of dependent outputs. Mark the job complete only after the final file and any companion caption track are stored and usable.
