CMU MoCap — De-jittered & Foot-locked (BVH)

96 motion-capture clips from the CMU Graphics Lab Motion Capture Database, converted to BVH and processed to remove two artefacts present in the source solve: high-frequency rotational noise, and foot sliding during ground contact.

Every clip ships with a .cleanup.json alongside it recording the before/after measurements, and the headline numbers are in metadata.jsonl too — so the processing is auditable rather than asserted. Across a 21-clip validation set spanning both frame rates and 21 subjects, rotational jitter improved on 21/21 clips (median 5.3x) and in-stance foot sliding fell by 81.9%.

The motion is CMU's and remains under CMU's terms. Our contribution is the cleaning and the measurements — see Licensing below, which includes a restriction you must pass on.

Retarget these onto your own characters. Sign up free — 1,000 export tokens, no credit card. Metrixel's motion retargeting accepts .bvh sources directly, so a folder of these clips can be applied to a rigged character in one command.

These are motion clips only — skeletons and animation, no meshes, skins or textures. Pair them with a rigged character (see Related) to retarget motion onto a body.

Licensing

The motion originates from the CMU Graphics Lab Motion Capture Database and is used under CMU's published terms. EntVista Studio does not own it and grants no licence over it.

• Free for all uses, including research and commercially-sold products.
• You may not resell the motion data itself, and CMU states this explicitly covers converted form — BVH, FBX, GLB or retargeted onto another character. Shipping a product containing it is fine; selling the data is not.
• This restriction transfers to you and to anyone you redistribute to.

If you publish work using this data, CMU asks that you include: The data used in this project was obtained from mocap.cs.cmu.edu. The database was created with funding from NSF EIA-0196217.

Source archive was the official allasfamc.zip bulk download; the database was not crawled.

Full terms in LICENSE.md. Read it before use — CMU permits free use and inclusion in commercially-sold products, but prohibits reselling the data itself even in converted form, and that restriction passes to you.

Honest limits

• The motion is not ours and the cleaning is not magic. Processing reduces jitter and foot sliding; it does not reconstruct missing markers, fix a bad solve, or add detail that was never captured.
• Foot locking assumes ground contact is detectable from contact-point speed. It is skipped where that fails — acrobatics, ladders, and motion with no clear stance phase.
• A small pelvis give is applied (capped at 4% of body height, low-passed at 2 Hz) where a foot pin would otherwise be out of reach. The root's horizontal trajectory is never modified.
• CMU skeletons vary by subject, including genuine left/right asymmetry. Clips are not normalised to a common rig — retarget rather than assuming a shared skeleton.
• These 96 are a curated subset, selected for measured improvement and motion variety, not a representative sample of CMU's 2500+ trials.
