# Execute Video Workflow

> Execute complex multi-step video processing workflows

Apply complex video processing workflows such as adding subtitles, overlays, or other transformations.

<CodeGroup>
  ```python Python theme={null}
  import videodb
  from videodb import SubtitleStyle

  conn = videodb.connect(api_key="your_api_key")
  coll = conn.get_collection()
  video = coll.get_videos()[0]

  # Add subtitles to video
  subtitle_style = SubtitleStyle(
      background_color="#000000",
      text_color="#FFFFFF"
  )
  stream_url = video.add_subtitle(subtitle_style)

  print(f"Video with subtitles: {stream_url}")
  ```

  ```javascript Node.js theme={null}
  import { connect } from 'videodb';

  const conn = connect({ apiKey: 'your_api_key' });
  const coll = await conn.getCollection();
  const videos = await coll.getVideos();
  const video = videos[0];

  // Add subtitles to video
  const streamUrl = await video.addSubtitle({
    backgroundColor: '#000000',
    textColor: '#FFFFFF'
  });

  console.log(`Video with subtitles: ${streamUrl}`);
  ```
</CodeGroup>

<Note>
  * Supports multiple workflow types (subtitles currently implemented)
  * Workflows modify video stream without changing original
  * Subtitle style customization includes colors, positioning, and fonts
  * Returns new stream URL with applied workflow
  * Original video remains unchanged
</Note>
