Questions, answered
How do I find the right offset quickly?
Find a sharp sound with a visible cause — a clap, a door, a tap on the desk — and align that single moment. The rest of the clip normally follows once that point is right.
My audio starts in sync and drifts out — will this fix it?
No. Progressive drift comes from a sample rate or frame rate mismatch, and shifting the whole track cannot correct it. The audio needs re-timing or re-exporting at a matching rate.
Should the audio be slightly early or slightly late?
Slightly early if you must choose. Viewers detect late audio more readily than early audio, which is why sound arriving a frame ahead is less noticeable than a frame behind.
How precise can the adjustment be?
Adjustment is in milliseconds, well below one frame. Sync errors become noticeable to most viewers somewhere around 40–50 ms of audio delay.
What if I only need to move the audio in one direction?
The delay tool adds silence to push audio later; the advance tool trims the head to pull it earlier. This tool covers both with a preview, which is easier when you do not already know which way it needs to go.
