4DV AI

4DV AI is an AI-powered video transformation platform that rebuilds ordinary 2D video footage into explorable 4D spatial environments using 4D Gaussian Splatting — a technique that represents scenes as millions of semi-transparent 3D particles called Gaussians, each carrying color, depth, motion, and positional data. The AI analyzes each frame of the source video to extract depth information, reconstructs a full 3D scene per frame using this data, then layers time across those frames to produce a dynamic 4D structure. The result is a scene that users can navigate freely during playback: shifting the camera viewpoint, zooming in on details, panning, or rotating — all while the scene continues to unfold in real time. The rendering engine is built on PlayCanvas and WebGL, meaning the entire interactive experience runs directly in a web browser with no downloads, plugins, or special hardware required. Spatial audio adjusts based on the user's position within the scene, adding another layer of immersion beyond visual perspective. The platform's demo is publicly accessible, featuring pre-processed 4D video samples that demonstrate real-time volumetric rendering in a browser environment. A GitHub codebase supports developers and researchers who want to build on or contribute to the underlying technology.

Unlike 360-degree video which locks the viewer into a single fixed viewpoint, 4DV AI's 4D system allows genuine spatial movement — users are not choosing between preset angles but freely positioning themselves within the reconstructed scene. The core differentiator over legacy volumetric video approaches is accessibility: traditional 3D video reconstruction required multiple synchronized cameras and days of processing time, while 4DV AI generates navigable 4D content from a single standard video input and runs the result in a browser tab. 4DV AI represents an early-stage but technically significant platform. The primary limitations at this stage are file size — 4D video data is substantially larger than standard video even with compression, which affects load times and bandwidth requirements — and the fact that high-quality source input benefits from multi-camera setups despite the single-camera capability. The tool currently showcases its technology through a demo viewer rather than a full self-serve upload pipeline for general users, meaning broad public content creation workflows are still in development. For researchers, developers, and forward-looking media professionals exploring volumetric video and the next generation of immersive content, 4DV AI is one of the few accessible entry points into production-grade 4D Gaussian Splatting technology running in a browser Read our guide.
