Video to Motion Capture
Online

Great results with:

• One person, fully visible, filmed from a static camera
• Walk cycles, exercise moves, dance, gestures, idle animations
• Even lighting and fitted clothing
• Clips between 10 and 60 seconds
• Reference for game animations, previz, and character blocking

May struggle with:

• Multiple people in frame, or the subject leaving the frame
• Loose clothing, capes, and skirts that hide the body outline
• Low light, heavy motion blur, or a fast-moving camera
• Limbs pointing straight at the camera (depth ambiguity)
• Acrobatics with rolls and flips where the tracker loses orientation

.BVH — Skeleton Animation

BVH (Biovision Hierarchy) is the standard interchange format for mocap. It stores a joint hierarchy plus per-frame rotations, so animation software can play it back on an armature immediately. Our skeleton uses 16 joints with bone lengths measured from the person in your footage, which keeps proportions correct when retargeting. Choose BVH if you animate.

.CSV — Landmark Trajectories

The CSV contains one row per frame with the 3D position and visibility score of all 33 tracked body points, in meters, Y-up, hip-centered. Each row also flags whether the pose was detected or interpolated. Choose CSV for biomechanics analysis, custom retargeting scripts, ML training data, or any pipeline where you want the numbers instead of a rig.

Blender

File → Import → Motion Capture (.bvh). Match the scene frame rate to the file and press play. Retarget to your own rig with constraints, Auto-Rig Pro, or Rokoko Studio Live.

Unity

Import the BVH into Blender first, export as FBX, then set the rig to Humanoid in Unity. The Avatar system retargets the motion onto any humanoid character.

Unreal Engine 5

Same route: BVH → Blender → FBX. Import the FBX as a skeletal animation, then map it onto your character with the IK Retargeter.
