# Add captions (https://www.getfounderhq.com/docs/studio/add-captions)

Studio listens to your video and writes the captions, timed to each word.
You choose the style and fix any word it misheard. About 2 minutes for a
short video.

<Callout title="Before you start">
You need an edit open in the [editor](/studio/edit-a-video), with a clip
that has speech. You also need one of these:

- [Companion](/companion) running on your machine. The captions are then
  made on your machine, at no cost.
- An OpenAI API key connected in [Settings → AI Provider](https://app.getfounderhq.com/?openSettings=ai-provider). A
  ChatGPT subscription does not cover captions.
</Callout>

## 1. Add the captions

Press **Captions** above the timeline. You can also ask Astro: "Add
captions to the whole video."

- With a clip selected, Studio captions that clip.
- With nothing selected, Studio captions every video and audio clip.

Studio sends only the sound of your clips, never the picture. The captions
appear on their own layer.

The first time Companion makes captions, it downloads a voice model of
about 490 MB. Later runs skip that step.

## 2. Choose a style

Select the captions on the timeline. Their settings open on the right.

| Setting | Options |
| --- | --- |
| **Style** | Clean, Bold, Karaoke, Pill, Neon, Typewriter |
| **All caps** | On or off |
| **Text colour** | Any colour |
| **Accent colour** | The highlight of the spoken word, in Karaoke, Pill, and Neon |
| **Box colour** | The box behind the words, in Pill |
| **Size** and **Position** | How large the captions are and where they sit |

## 3. Correct a word

The **Transcript** under the style settings lists every word. Click a word
to edit it and press Enter. Clear a word to delete it.

## Verify

Play the video in the preview. The captions follow the speech, in the
style you chose.

## Languages

Studio detects the language. With Companion, captions work in 25
languages: Bulgarian, Croatian, Czech, Danish, Dutch, English, Estonian,
Finnish, French, German, Greek, Hungarian, Italian, Latvian, Lithuanian,
Maltese, Polish, Portuguese, Romanian, Russian, Slovak, Slovenian,
Spanish, Swedish, and Ukrainian. For any other language, Studio uses your
OpenAI API key.

## Troubleshoot

### "Please set up an OpenAI API key to use this feature."

No Companion is online and no OpenAI API key is connected. Open Companion
on your machine, or add a key in [Settings → AI Provider](https://app.getfounderhq.com/?openSettings=ai-provider).

### "This clip has no audio track."

The clip is silent. Select a clip that has sound.

### "No speech lines up with these clips."

Studio found no words in the sound, or the speech falls outside the part
of the clip you kept. Check that the trimmed clip still contains the
speech.

### "Audio is larger than the 25MB transcription limit."

The sound of the selected clips is too long for one request. Select one
clip at a time and caption each.

### "Media is still preparing — try again in a moment."

A clip you just added is still loading. Wait a few seconds and press
**Captions** again.
