Holo-World: Unified Camera, Object and Weather Control for Video World Model
TLDR
Holo-World unifies camera, object, and weather control in a video world model from a single image, using a dataset and novel adapters.
Reasoning
The paper introduces a novel unified framework for controlling camera, object, and weather in video generation from a single image, with a dedicated dataset and decomposition technique. Strengths include addressing isolated controls and weather transfer; weaknesses include limited scope (first-frame-anchored) and lack of explicit real-world deployment details.

Innovations
- First-frame-anchored source-to-state setting for video world models, enabling generation from a single image with explicit camera, object, and optional weather control.
- HoloStateData dataset that converts diverse videos into unified control samples for camera, object, and weather supervision.
- Unified Scene Adapter that factorizes world preservation and weather transfer into distinct parameter subspaces using rendered background, geometry buffers, and object controls.
- Scene-Weather Decomposed CFG (Classifier-Free Guidance) that separately guides scene and weather residuals to strengthen target weather effects without over-amplifying the full condition.
Methodology
The paper proposes Holo-World, a unified controllable video world model. It first builds HoloStateData, a dataset that transforms diverse videos into samples with camera, object, and weather annotations. The model uses a Unified Scene Adapter to maintain controlled scene structure via rendered background, geometry buffers, and object controls while modeling weather-dependent appearance and particle effects. Additionally, Scene-Weather Decomposed CFG guides scene and weather residuals separately to enhance weather effects without distorting the scene.
Key Results
Quantitative and qualitative experiments show that Holo-World maintains precise camera and object control with consistent scene structure while transferring scenes into diverse target weather states, outperforming video-to-video weather editing baselines on weather-state generation.
Limitations
- The approach requires explicit camera and object controls as input, which may not always be available in real-world applications.
- Weather generation is limited to the weather states present in the HoloStateData dataset, potentially missing rare or extreme conditions.
- The method is evaluated only on weather-state generation tasks; its performance on other environmental changes (e.g., lighting, season) is not addressed.
