How can you verify temporal alignment between audio and picture after ADR?

• A. Matching lip-sync frames with timecode, using a video reel, and visually inspecting mouth movement.
• B. Relying on the producer's notes to align.
• C. Checking waveform loudness in a DAW and ignoring video.
• D. Only ensuring audio length matches video duration, without timing.

Answer: (A)

Temporal alignment after ADR is about locking the new dialogue to the exact frames of the picture, so the spoken words line up with the actor’s mouth movements at every moment. The best way to verify that is to use the ADR timecode as an anchor, reference the actual video timeline with a reel, and visually check that the mouth shapes and lip timing match the spoken lines. Timecode gives precise frame-by-frame positioning, the video reel provides the visible reference for when each syllable should occur, and a careful visual check confirms that the dialogue hits the right points in the performance. Together, they catch offsets, late starts, early finishes, or timing shifts that wouldn’t be revealed by audio alone.

Relying on producer notes doesn’t give the required frame-accurate precision. Checking the waveform while ignoring video won’t reveal if the words are out of sync with the actor’s lips. Merely matching audio length to video duration can hide internal timing errors within the scene. Using the timecode, video reference, and mouth-movement verification ensures the ADR truly aligns with the picture on a frame-by-frame basis.
