The official version will be released within this week. Please stay tuned.
Dear UniFab Community Users,
Thank you for your continued attention and support for our AI colorization tool! Building on the previously released Video Colorizer AI, we are excited to announce the all-new multi-scene intelligent colorization V2 version, bringing your video projects more professional and natural color effects, with a richer and more comprehensive colorization experience!

🚀 What’s New & Key
Colorizer V1
The V1 version mainly relied on a single-scene reference frame for colorization, suitable for videos with a fixed, single-camera shot. However, when switching between shots or multiple scenes occurred, color inconsistencies could appear, affecting the overall viewing experience.
Breakthrough in V2
🌟 Intelligent Multi-Scene Segmentation
Version 2 automatically detects and segments multiple scenes in your video and applies detailed colorization to each shot, effectively fixing the color breaks caused by scene changes in v1.
🎨 Scene-Specific Color Profiles
Each scene is colorized with a custom palette for more accurate, natural, and softer colors, plus richer image layering—greatly enhancing overall visual quality.
⚡ Consistent & Refined Color Performance
Whether it’s fast-cut editing or complex content, v2 maintains high-quality, layered, and lifelike coloring, significantly improving both your editing experience and final results.

📋 How to Use
- Upload your video: Import a black-and-white video to start.
- Generate reference frames: These are automatically created to guide colorization across the entire video.
- Preview and pick a style: Choose from four pre-generated color styles.
- Select multi-scene mode: The system detects different scenes and intelligently applies the chosen style.
- Generate the full video: AI maps your selected style to every frame for consistent and dynamic results.
- Export your file: Edit and save in your preferred format, just like with other UniFab tools.

- The launch of V2 does not affect the existing single-scene colorization V1 version; you can continue to use it without concern.
