# Key features

**Bulk Colorization**: With a simple script, colorize over 1 million images per day. This is ideal for large archives or professional colorists managing extensive projects.

**Video Integration (Beta)**: The Video API enables you to affordably colorize SD, Full-HD, or 4K video frames. Major production companies and TV channels around the world are already leveraging Palette.

**App Integration**: Integrate Palette directly into your iPhone photos, Google Drive, or your favorite photo app. Use the API to develop a new app or enhance an existing product with our powerful feature set.
