One click. A 3D body that sticks to the actor in your shot.
AI mocap gives you a skeleton floating in its own space, with no camera and no lens, so it slides off the plate. Body Tracker solves the body in your shot camera, with the plate behind it, so it lines up with the actor: shadows, holdouts, CG costumes and effects that stick. No markers, no suit, no uploads. Everything runs on your own GPU, so client footage never leaves your PC.
What it does
Locked to your plate
The body sits in the shot camera with the lens estimated from the image, or type your real lens. Orbit around it: it stands where the actor was.
Everyone in the shot
All-people mode gives one animated body per person. Four dancers, one click.
Apply to your character
Move the motion onto a Mixamo, Rigify or custom rig. Hips stay on the plate, and planted feet are pinned with IK.
Export to game engines
New in 0.6: one click writes your character with the shot’s motion as FBX or GLB for Unreal Engine, Unity or the web, with an In place option for game loops.
Clean motion
Jitter smoothing that keeps fast moves, foot lock on contacts, and gap filling when the actor is hidden for a moment.
An honest report
For every shot: how well the body matches the actor frame by frame, the frames and joints to review (with jump buttons), and the lens used.
Measured, not guessed
1.7–2.9% of body height overlay error on test clips with known answers. About 1.2 s per frame on an RTX 5070 Ti, and 4K takes only about 9% longer than 1080p.
Pay once
Every 1.x update is included, with 12 months of support. No online activation.
Watch before you buy
Know before you buy
- Windows 10/11 (64-bit) and an NVIDIA RTX GPU with 8 GB+ memory. Mac and AMD GPUs are not supported yet.
- About 15 GB of disk for the engine and models. Internet only for the first install.
- A free Hugging Face account: you accept Meta’s SAM License for two models before the installer downloads them.
- Body only: hands are basic, no face yet, and loose clothes and hair are not modelled. It is not a mocap suit.
- A moving camera works in camera space; world space needs a solved camera.
- Refund within 14 days if it won’t run on a PC that meets these requirements and we could not fix it together.
