Clear audio does more for a video than most people expect — viewers will forgive shaky footage far more easily than they'll forgive audio they have to strain to hear. Here's how to get captions and sound in good shape before you export.
Cleaning up background noise
The app can reduce background hiss, hum and wind noise while pulling voices forward in the mix. It works best on dialogue-heavy clips shot with a phone mic. It's a helpful pass, but it isn't magic: a clip recorded next to genuinely loud noise, like traffic or a crowd, will still need a quieter retake for the best result.
Balancing volume between clips
Because each clip carries its own volume setting, footage recorded at different times or distances from the subject often ends up uneven once it's all cut together. Go through your assembled timeline and nudge each clip's volume up or down until the transitions between them feel smooth rather than jarring.
Generating captions automatically
Once your audio is in decent shape, auto-captions can save a significant amount of manual typing. The app transcribes your dialogue and places timed captions on the timeline for you to review. Auto-transcription is rarely perfect on the first pass, so plan to skim through and fix names, slang or anything mumbled before you move on.
Styling captions to match your edit
Once the timing and text are correct, you can restyle captions — font, size, color and position — and save that combination so you don't have to rebuild it from scratch on your next project.
