/synchronize-clips

Computes the offset (and a clock-drift sanity check) needed to align a high-quality mic recording with a camera recording of the same speech, by combining word-level ASR timestamps with local cross-correlation. Reports the result and, when applicable, applies it in Premiere by building a synced sequence (see Applying the offset).

Running the command

Run in any environment with premiere-ai installed (Conda, uv, venv, or otherwise — only the package needs to be available, not a specific tool):

sync-audio "<camera_file>" "<mic_file>"
