Sync captions to speech

Sync the captions precisely to speech for the 2:30 marketing spot ‘Hero Ad Final.’ Adjust timing so each caption appears within 0.1 seconds of the corresponding audio, tighten any gaps longer than 0.15 seconds, and make sure long captions split at natural pauses. Export a burned-in MP4 and a timed SRT named HeroAd_Final_Timed.srt.

Before I hand this to the media buyer, make caption sync perfect for inattentive viewers. Ensure every line starts as speech begins, hold captions through short silent beats so reading doesn’t jump, and avoid rapid two-line changes in under 0.5 seconds. Flag any sections where mouth movement and caption timing look off for ADR or transcript correction.

In Hero Ad Final there’s a 0.3–0.5s delay where a caption stays visible after the line is spoken, which will look off on pause and slow viewers’ comprehension. The media buyer will complain about perceived low quality. I can nudge timings manually but I don’t know whether to shorten the caption duration or move its start earlier. Which adjustment yields the most natural result for viewers?

I’m spending hours nudging caption in/out points after every small edit, and the backlog is growing. This erodes my capacity to deliver on time and keeps our channel inconsistent. What habit, tool setting, or mini-template would cut caption sync time by half while keeping quality good enough for paid placements?
