AIMoCap vs Uthana

AIMoCap is a browser-based AI motion-capture platform that converts uploaded videos into 3D animation for animation and robot-motion workflows. In its web workspace, users upload a source video, trim the motion segment, choose a target, submit processing, then preview or download the result. It captures body and finger motion together and aims to preserve natural weight shifts while reducing visible foot sliding. Targets include Default, MMD, Mixamo, CC&iClone, Roblox R15, custom humanoid characters, and Unitree G1 robot output. Humanoid exports are FBX animation files; Unitree G1 exports Mujoco-oriented JSON motion data. Output frame rates are 24, 30, 60, and 120 fps. The asynchronous API uses bearer keys and supports batch jobs. A free plan is available; paid plans start at $9.90 per month. Custom robot uploads are planned for later.

Uthana provides human-motion models, data, and embodiment tools for robots, simulations, and 3D characters through web and API access. It generates editable 3D motion from text or video, including full-body skeletal movement with finger motion from ordinary video, and offers controllable locomotion. Movement can be retargeted between bipedal skeletons or adapted to a humanoid robot representation; that robot output does not include a complete control policy or dynamics model and does not guarantee hardware execution. Exports include FBX, GLB, and BVH, with FBX presets for Unreal Engine 5 and Roblox Studio. Uthana offers a GraphQL API and public Blender and Maya plugins, plus scripting support and deployment both ways. Its Studio Motion Dataset contains 250+ hours, while more than 1,000 hours across collections are available to license. Listed monthly prices range from 0.01 USD for stitching and looping to 0.75 USD for character generation. Uthana stopped offering new subscriptions in August 2026; existing subscribers may continue unless they switch.
