Create captions for the timeline "[TIMELINE NAME]".

1. Use the app's own transcription if this tool supports it, otherwise transcribe the dialogue track locally and build an SRT.
2. Caption rules:
   - max [42] characters per line, max 2 lines (vertical video: 1 line, max 28)
   - reading speed under 20 characters per second
   - each caption on screen between 0.8 and 6 seconds
   - never split a name, a number and its unit, or an adjective and its noun across lines
3. Correct these names and terms exactly as written: [Name One, Brand Two, Product Three].
4. Import the captions as a caption or subtitle track, not as burned in graphics.
5. Apply the style: [font], [size], white text, [outline or box], bottom center, inside the title safe area.
6. List the 5 captions you are least sure about with timecodes so I can check them.
