# Importing .srt subtitles into Remotion

If you have an existing `.srt` subtitle file, you can import it into Remotion using `parseSrt()` from `@remotion/captions`.

## Prerequisites

First, the @remotion/captions package needs to be installed.
If it is not installed, use the following command:

```bash
npx remotion add @remotion/captions # If project uses npm
bunx remotion add @remotion/captions # If project uses bun
yarn remotion add @remotion/captions # If project uses yarn
pnpm exec remotion add @remotion/captions # If project uses pnpm
```

## Reading an .srt file

Use `staticFile()` to reference an `.srt` file in your `public` folder, then fetch and parse it:

```tsx
import {useState, useEffect, useCallback} from 'react';
import {AbsoluteFill, staticFile, useDelayRender} from 'remotion';
import {parseSrt} from '@remotion/captions';
import type {Caption} from '@remotion/captions';

export const MyComponent: React.FC = () => {
  const [captions, setCaptions] = useState<Caption[] | null>(null);
  const {delayRender, continueRender, cancelRender} = useDelayRender();
  const [handle] = useState(() => delayRender());

  const fetchCaptions = useCallback(async () => {
    try {
      const response = await fetch(staticFile('subtitles.srt'));
      const text = await response.text();
      const {captions: parsed} = parseSrt({input: text});
      setCaptions(parsed);
      continueRender(handle);
    } catch (e) {
      cancelRender(e);
    }
  }, [continueRender, cancelRender, handle]);

  useEffect(() => {
    fetchCaptions();
  }, [fetchCaptions]);

  if (!captions) {
    return null;
  }

  return <AbsoluteFill>{/* Use captions here */}</AbsoluteFill>;
};
```

Remote URLs are also supported - you can `fetch()` a remote file via URL instead of using `staticFile()`.

## Using imported captions

Once parsed, the captions are in the `Caption` format and can be used with all `@remotion/captions` utilities.
