BruxoSplat is a free, open source desktop app that turns ordinary videos into 3D scenes on your own computer using your graphics card. It was built by a group called Bruxos do VFX as a no-cost alternative to a paid tool called Postshot. The workflow is straightforward: you pick a video, press a button to start training, and the result opens directly in a bundled editor where you can add effects, crop, animate the camera, and record video. The core pipeline works in stages. First, the app extracts frames from your video. Then it figures out where the camera was positioned for each frame, using either COLMAP (the standard method) or faster alternatives like DPVO, MASt3R, and MegaSam. Finally, it trains a Gaussian Splat, which is a 3D representation made of many soft points, using a training engine called Brush or newer experimental engines. The finished file opens in the built-in editor for further work. Beyond the classic video pipeline, version 1.1 adds several AI models that generate 3D output from other inputs. SHARP creates a 3D scene from a single photo. TripoSplat produces a full 360-degree 3D asset from an image. FaceAnything turns video of a face into a moving 4D model. Each model runs in its own isolated Python environment so they never conflict with one another. The app also handles 4D sequences, meaning series of 3D frames played over time. You can import folders of these files, play them at adjustable speeds, convert them to a smaller format for faster playback, and export them as individual files or as a single streaming file. BruxoSplat runs on Windows 10 or 11 with a dedicated graphics card having at least 4 GB of memory, and on macOS 12 or later. Some AI models require an NVIDIA card. Ready-to-use installers are available for both platforms, and the app automatically downloads the tools it needs on first run. The full README is longer than what was shown.
