</Frame>

## Edit captions

After captions are generated, you can edit them directly:

* **Fix text** - Click on any caption on the timeline to edit the text
* **Adjust timing** - Drag the edges of a caption to change when it appears and disappears
* **Delete a caption** - Select it and press **Delete** or **Backspace**
* **Split captions** - Break long captions into shorter segments for better readability

<Tip>
  You can also ask the AI to make caption edits: "Fix any misspelled words in the captions" or "Break long captions into shorter lines."
</Tip>

## Custom styling

For each caption, you can customize:

* Font, size, and color
* Background color and opacity
* Text position on the screen
* Animation style (fade in, pop in, slide in)

<Note>
  Click on "apply to all" button so that every caption in your project updates to match the style.
</Note>

## Supported languages

Cardboard can transcribe and generate captions in 20+ languages. Choose "Auto" so that AI auto-detects the spoken language. You don't need to specify it manually.
