Plask Motion

The core job is estimating a full body pose from ordinary footage and applying it to a rigged character. Plask runs two extraction engines: V1 favors smooth, flowing movement, while V2 adds ground recognition with foot correction and compensates for a moving or rotating camera. Both handle vertical video, and V2 lets you pick which person to track when several appear on screen. Extracted animation stays editable in the workspace, so you can nudge timing after the AI finishes rather than re-shooting.

Body tracking alone leaves hands locked in a default grip, which reads as stiff in close shots. The hand animation option adds finger joints on the V1 engine, and multi person mode animates up to a small group from one clip. Both cost credits, and multi person runs at three credits per frame. For a podcast clip or a street scene with extras, that turns a single recording into several animated characters.

Plask opens GLB, FBX (version 7100 or later), VRM 0.0, and PMX files up to 50 MB. Models need a mesh and a skinned skeleton, and a T pose as the rest state, with a minimum of 24 source bones. Retargeting is tuned for a 52 bone structure covering hips through fingers. VRM and PMX models keep physics simulation through Babylon MMD, so hair and clothing follow the body, and automatic blinking adds a layer of life that plain rigs lack.

Plask Live brings realtime capture into the tools animators already use. In Blender, you preview the movement, record a take, and save it as an action you can animate against. In Unreal Engine, the Live Link plugin receives the pose stream and saves a take directly. Setup needs macOS 14 or later, Python 3.12, and API credits, and the camera helper is built locally from source. Setup takes patience. Once it runs, the export and import round trip that breaks the flow of a take disappears.

The workspace includes cinematography controls that many mocap tools leave out. You position the camera, add lighting, and apply effects such as motion blur and depth of field, then render a finished video. That matters for creators who need the clip rather than the animation file: a dance video or a product teaser comes out of the browser without a trip through a separate render package.

The Plask API exposes video job processing and realtime pose streaming for your own application. Video jobs run through batch GPU workers, with progress events over server sent messages and download of the finished result. Realtime sessions stream JPEG frames over WebSocket and return poses on a standard 24 joint skeleton in metres. Usage is metered in credits, with a separate test allowance for development keys. Fitness apps, dance trainers, and motion studies are the obvious fits.
