What is Plask Motion?

Plask Motion is an AI-based motion capture tool that works entirely in the browser. The proposition is simple: upload a video of a person moving, and Plask automatically extracts movement data (joint positions, rotations) and applies them to your 3D rig. No sensor suit, no dedicated studio, no heavy software. The workflow covers motion extraction, basic animation editing (foot correction, smoothing, adjustments), and export in standard formats (FBX, BVH) compatible with Blender, Maya and Unity.

Strengths

Mocap without hardware

Accessibility is the main differentiator. A smartphone camera and a decent video are enough to get usable movement data. The entry cost is negligible compared to traditional mocap systems.

Directly in the browser

No installation, no configuration. The mocap workflow happens entirely in Chrome. For independent creators, this is a break from traditional workflows.

Export to standard DCC

FBX and BVH export ensures compatibility with Blender, Maya, Cinema 4D and game engines like Unity and Unreal.

Limits

Limited precision vs professional mocap

Plask's precision remains below professional optical or inertial mocap systems (OptiTrack, Xsens). For high-end commercial productions, artifacts are still visible.

Quality dependent on source video

Poor lighting, occlusions or overly fast movements significantly degrade capture quality. Shoot preparation is important.

Pricing

From $20/month. A free plan with limitations is available. Check plask.ai for plans.

Alternatives

For accessible traditional mocap: Radical.ai. For procedural animations: Cascadeur. For rigged animations without mocap: Mixamo (free Adobe).

Verdict

Plask Motion democratizes motion capture for independent creators. The quality level achieved is remarkable for a browser-based solution without hardware. For productions requiring maximum precision, professional alternatives remain necessary.
