# Add captions or repackage talking-head footage
> Add captions, add designed overlays, or change the spoken edit.
## Make the request
Name the file and the change you want:
```text theme={null}
Using /hyperframes, add clear animated captions to assets/interview.mp4.
Keep the footage and its spoken edit unchanged.
```
Ask for designed information cards instead when the footage needs titles,
quotes, statistics, lower thirds, or picture-in-picture.
## What should change?
* **Add captions** — keep the original clip and audio unchanged; add readable, timed words over it.
* **Add designed overlays** — keep the clip underneath and add titles, quotes, statistics, lower thirds, or picture-in-picture.
* **Change the footage** — use General Video when pauses, selected moments, or the spoken order must change.
Captions and designed overlays work best on a clear, single-subject clip with audible speech. Both keep the original footage and audio intact.
If you need to remove pauses, choose different moments, or reorder the speech, use [General Video](/guides/general-video).
## Before it builds
Confirm:
* **Captions:** the intended format and any names or terms the transcript may miss. HyperFrames can recommend a visual treatment after it sees the clip.
* **Designed overlays:** the format, layout, visual style, and how often a title, quote, statistic, or side panel should appear.
* **Either path:** where the speaker, existing text, and important action leave safe room for graphics.
## Review what matters
* Names, product terms, and numbers are correct.
* Captions follow the spoken words.
* Graphics avoid faces and important parts of the footage.
* The video works with sound and muted.
* The final caption or graphic clears before the video ends.
For direct placement changes, use [Captions in Studio](/studio/captions) to
inspect synchronization and save position, scale, or rotation corrections. Ask
the agent or edit the caption source for corrected words and durable timing or
style changes.
Review the chosen caption, overlay, or recut path, then render and watch the final file.
