Fable introduces .splat4d for compressed 4D Gaussian Splatting
July 4, 2026
Fable developed the .splat4d format, which uses a static/dynamic split and H.265-style GOP encoding to compress 4D scenes. A 2-second dynamic scene is reduced to a 7.4MB file, representing a 58x reduction compared to raw .splat frames, and is decodable in browsers via WebGPU.
