Video editing has traditionally required frame-by-frame masking or complex 3D tracking software. UniVideo changes this by allowing you to edit videos using simple English sentences.
What is Free-Form Editing?
Free-form editing refers to the capability of the AI to interpret a wide range of commands without being restricted to specific "modes" (like only style transfer or only color grading). Because UniVideo is built on a Multimodal Large Language Model (MLLM), it understands the semantics of your video just as well as it understands your text prompt.
Examples of What's Possible
1. Style Transfer ("The Vibe Shift")
"Transform this video into a Cyberpunk 2077 cinematic trailer."
The model identifies the key elements—buildings, cars, people—and re-renders them with neon lights, rain, and futuristic textures, while maintaining the original motion and camera angle.
2. Object Replacement
"Replace the dog with a tiger."
Unlike simple overlay tools, UniVideo understands lighting and perspective. The tiger will walk, run, or sit exactly where the dog was, interacting with the environment realistically (e.g., casting shadows).
3. Environmental Control
"Make it look like a snowy day."
The model doesn't just apply a white filter. It adds snow accumulation on surfaces, falling snowflakes with depth, and changes the lighting to reflect a gloomy winter sky.
How It Works Under the Hood
This capability is powered by Zero-Shot Generalization. UniVideo transfers knowledge from massive image-editing datasets. It has "seen" millions of examples of "photo of a dog" vs "photo of a tiger" and learned the transformation rules. By applying these rules through the Unified Video Flow (UVF), it extends this logic to the temporal dimension of video.
