Captions
Captions narrate the video: a short line per key beat, timed to the action. Your agent writes the copy — it already knows what the feature does — so you steer the intent, not the wording.
/reely Add captions that explain each step.
Steering the copy
Captions are short by design — under six words, so the bar never wraps into a paragraph — and they narrate only what is on screen. Tell the agent the register you want.
| You want | Say |
|---|---|
| Marketing punch | “Benefit-led captions, like a product launch.” |
| Plain and factual | “Neutral captions — describe what happens, no hype.” |
| Fewer of them | “Only caption the three most important beats.” |
| Your own words | “Use exactly these lines: … , … , …” |
Captions appear automatically when the video is authored with caption copy. Say “no captions” to suppress them, or “add captions” to force them on.
The typeface
Captions can be set in your app’s own font, a font file from your repo, or one of ten built-in faces.
| Choice | Ask for it like |
|---|---|
| Your app’s embedded font | “Set the captions in our app’s font.” |
| A font file in your repo | “Use Sources/DS/Fonts/Inter-Medium.ttf for captions.” |
| A built-in face | “Use Avenir Next for the captions.” |
| The system font | “Use the system font for captions.” |
- Helvetica Neue
- Avenir Next
- Futura
- Gill Sans
- Optima
- Georgia
- Palatino
- Baskerville
- American Typewriter
- Menlo
Where captions sit
By default they sit as a lower third under the phone. On a 16:9 canvas they move beside the phone instead: it parks to one side and the copy takes the freed margin, alternating sides between groups of captions. That is what makes a landscape video read like a product page rather than a phone with a stripe under it.
/reely Make it 16:9 with captions beside the phone.
Colors follow your brand when the video is branded from your app, or you can name them outright.
