Cartwheel Video to Motion by Cartwheel extracts body animation from any video without markers or a studio. Upload up to 30 seconds of footage, the engine tracks up to four people and produces retargeted motion ready to apply to your character. The Comic 4 pipeline adds facial capture. Outputs include GLB and FBX for Blender, Maya, Unreal, and Roblox. Export controls cover frame rate, axes, frame step, looping, and keyframe cleaning. Best for game developers and 3D animators needing fast, production-ready motion from live-action footage.
