Transcribe media and create captions

Turn speech into editable text, synchronize it, and finish the captions in Studio.

Transcription creates timed words from audio or video. Captions turn those words into a readable visual layer.

A practical workflow

1. Transcribe the media

   Ask the agent to transcribe the source, or use the CLI:

   npx hyperframes transcribe interview.mp4
   
2. Correct the text

   Fix names, product terms, numbers, punctuation, and obvious recognition errors before styling.

3. Create caption segments

   Group words into short readable phrases while keeping their timing connected to the speech.

4. Edit in Studio

   Open Captions to adjust text, timing, placement, style, and animation.

5. Review twice

   Watch once with sound for synchronization and once muted for readability.

Good caption decisions

• Keep lines short enough to scan.
• Break on meaning rather than an arbitrary word count.
• Do not cover faces or product controls.
• Use emphasis sparingly.
• Keep contrast reliable as the background changes.
• Preserve the exact spoken meaning.

Use Captions or recuts when starting from existing talking-head footage.
