1. Text
2. Narration
3. Background
Custom gradient
135°
4. Cadence
1.00x
Speeds up or slows down both the audio and the caption timing together — the export runs at this speed. Word sync (auto or tapped) stays correct either way.
5. Timing
Measures the actual volume of your recording to find real pauses between phrases, then places words in the speech in between — much closer than guessing by word length.
Advanced: tune pause sensitivity
280ms — if it gets ahead of the audio, drag this right; if it lags behind, drag it left.
6. Caption Style
Advanced caption options
3 lines
7. Persistent Heading
Advanced heading options
Preview plays in-page. Export re-plays the audio once in the background to render the file — for a 30s clip that takes about 30s.
