Plask Motion

Plask Motion is a browser-based AI motion capture tool that converts ordinary video into 3D animation data, exportable to Blender, Maya and Unreal.

Plask Motion removes the hardware barrier from motion capture. Instead of mocap suits or depth sensors, it uses AI to analyze webcam, phone or downloaded video and reconstruct body (and limited finger) motion as 3D animation data. Everything runs in the browser, with an integrated editor for cleaning up motion, applying it to imported characters and adding cameras, lighting and post effects. The tool supports common 3D formats (GLB, FBX, VRM, PMX) and exports high-quality renders or motion assets compatible with industry-standard software like Unreal, Maya and Blender. This makes it useful for game developers, VTubers, indie animators and students who need believable motion quickly and cheaply. Developed by a South Korean startup, Plask has expanded its capture quality over time, including a more powerful MoCap Pro offering. As with all video-based capture, results depend on footage quality and can require cleanup, but it dramatically lowers the cost and complexity of getting usable motion data.
