China’s 4DV AI technology transforms flat 2D videos into fully explorable 4D scenes. Users can now move within the footage, changing perspectives and interacting with digital environments.
By adding depth and spatial motion, this tool creates a dynamic viewing experience. Its potential spans gaming, virtual tours, and filmmaking, turning passive video content into engaging, navigable worlds.
2D To 4D Transformation
China’s 4DV AI uses a method called 4D Gaussian Splatting to transform 2D videos into immersive 4D scenes. It analyzes each frame to extract depth and motion details, building a dynamic, explorable environment.
In the YouTube video below, Lifecast.ai demonstrates how this technique maps pixels into 3D space using Gaussians that capture color, depth, and opacity over time:
The result lets users navigate scenes in real time, shifting viewpoints and experiencing moments from multiple angles.
Real-Time Browser Interaction
The 4DV AI platform allows users to explore 4D scenes directly within a standard web browser. This removes the need for specialized software or expensive hardware setups.
In the following Instagram post, the system is shown running on a lightweight browser engine called PlayCanvas, offering smooth camera control and even audio changes based on user position. Users can shift viewpoints, zoom, and pause scenes in real time:
The technology supports desktops and smartphones, making immersive video experiences widely accessible.
Applications Across Industries
4DV AI has wide applications across industries. In gaming, it helps developers turn simple video footage into immersive, explorable environments that enhance player engagement.
Real estate agents use it for virtual property tours, while filmmakers and advertisers transform flat shots into interactive 3D scenes. Education also benefits with dynamic lessons that let students explore sites or models.
In the following tweet, a 4D capture studio shares how they use Gaussian Splatting for high-fidelity, real-time 6-DoF spatial captures:
Their work ranges from VFX shots and sports scenes to preserving family memories as interactive 3D experiences. This highlights the growing potential for commercial applications across entertainment, education, and personal archiving.
