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
You can also ask the AI to make caption edits: “Fix any misspelled words in the captions” or “Break long captions into shorter lines.”

​
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)
Click on “apply to all” button so that every caption in your project updates to match the style.

​
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.
