¶ 2.10.1 Introduction
What can Video Colorizer AI do?
Video Colorizer AI is a powerful AI-driven tool designed to automatically add realistic color to black-and-white videos. Whether you're working with vintage home footage, historical films, or archival recordings, this tool brings your content to life with vibrant, natural-looking colors.
Highlights of Video Colorizer V2 Official Version
- Multi-Scene Colorization Mode
The official release of Colorizer V2 introduces two new modes within the Multi-Scene Colorization feature: High-Speed Mode and Normal Mode. You can flexibly choose the appropriate mode based on the priority of your colorization tasks to improve processing efficiency. With the Multi-Scene Colotization mode, UniFab Video Colorizer can intelligently split videos into multiple different scenes and automatically match the optimal reference frame for each scene, ensuring more accurate colorization results.
- Colorization Model Optimization
Previously, the Colorizer model used in the client generated preview images that sometimes exhibited color bleeding and distortion in complex scenes (such as grassy areas, animals, and other multicolored regions), which affected overall colorization quality. This official release replaces the old model with a brand-new one, significantly enhancing detail representation and color fidelity. It effectively eliminates issues like color bleeding, delivering clearer and more natural colorization results.
