# Create Custom Thumbnail

> Generate a custom thumbnail from a specific video frame

Generate a custom thumbnail image from a specific timestamp in the video.

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

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

  # Generate thumbnail from specific timestamp (in seconds)
  thumbnail = video.generate_thumbnail(time=5.0)

  # thumbnail is an Image object
  print(f"Thumbnail URL: {thumbnail.url}")
  print(f"Thumbnail ID: {thumbnail.id}")
  ```

  ```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];

  // Generate thumbnail from specific timestamp (in seconds)
  const thumbnail = await video.generateThumbnail(5.0);

  // thumbnail is an Image object
  console.log(`Thumbnail URL: ${thumbnail.url}`);
  console.log(`Thumbnail ID: ${thumbnail.id}`);
  ```
</CodeGroup>

<Note>
  * Time parameter is in seconds, can be a float (e.g., 2.5 for 2.5 seconds into video)
  * Returns an Image object with URL and metadata
  * Generated thumbnails are stored and can be retrieved later
  * Time value should be within video duration (0 to video.length)
  * Multiple thumbnails can be generated at different timestamps
</Note>
