About it
A video is a string of photos from a moving camera. If the scene stands still, each frame shows it from a slightly different place, and that is enough to rebuild it in 3D. This splash picks the sharpest frames of your stretch, finds the same small details in many of them and works out where the camera was for each one. That is structure from motion. Then it trains 3D Gaussian splats: starting from those points, it nudges each splat's place, size, shape and color until the scene, seen from each camera, looks like that frame.
It all runs on your device's graphics card, and nothing is uploaded. Film by walking slowly around an object or through a place, so the camera moves sideways: 10 to 40 seconds, steady, with texture. Turning on the spot, a tripod, blank walls, sky, water and blur give it nothing to match. On a phone, the phone-safe setting keeps it quick and cool.

Details
- Your own files
- video/*, .mp4, .m4v, .mov, .webm
Limits
- WebGPU
- Training needs WebGPU. Without it, only the baked samples open.
- File size
- Up to 40 MB. A larger video is refused.
- Time
- At High, up to 60 frames and 7,000 training steps, which the tool guesses at 9 to 27 minutes.
- Footage
- Blank, motionless, and fast-panning clips are all flagged as unlikely to make a clean scene. The flag is an estimate, and Start stays open.
