DeepMotion - AI Motion Capture & Body Tracking

Animate 3D extracts full-body motion from a single ordinary video, no markers, no suit, no depth camera. You can film on a phone or pull a clip from an archive, and the AI handles tracking and retargeting onto a rigged character. That removes the two biggest barriers to mocap for small teams: equipment cost and studio time. No suit to rent. No stage to book.

The platform tracks facial expressions and hand gestures from the same footage it uses for the body, so lip movement and finger articulation come through without extra hardware. Hand tracking is precise enough for sign language and detailed gestures. Very fast finger motion still produces occasional artifacts, which the Rotoscope Pose Editor is built to clean up.

SayMotion generates 3D motion from a written prompt, using DeepMotion's motion dataset as the source. You describe the action, pick a character and get multiple variants to choose from. It's the part of the platform that feels genuinely different from a traditional mocap pipeline, since you can produce a movement that never existed on camera. Most motion capture software makes you supply the performance; this tool lets you describe it.

Animations rarely come out perfect, and SayMotion's editing layer is where most of the practical value sits. Inpainting inserts new motion into an existing animation, Loop matches the first and last frames so a cycle repeats without a visible jump, Merge combines variants into longer sequences and Refine applies a creativity scale to adjust motion detail. For a walk cycle, Loop alone can save hours of manual keyframing.

The Rotoscope Pose Editor is a frame-by-frame correction tool that overlays your animation on the source video so you can drag a joint back where it belongs. It supports multi-joint selection, interpolation between two poses and keyboard shortcuts, and edits auto-save as you go. DeepMotion holds a patent pending on it, and the Free Animation Credit Program pays you back credits for using it.

Physics Simulation reduces impossible movement, like a hand passing through a leg, and Motion Smoothing uses filters to remove jitter. Both are configurable per job, and both matter more than they sound: raw AI tracking wobbles, and the difference between a stiff result and a convincing one often comes down to these two settings.

Upload your own FBX, GLB or VRM character, or build one with the integrated Ready Player Me and Avaturn creators. The AI retargets animation onto whatever character you choose, and higher plans raise the number of custom characters you can store, from 3 on the free tier up to 100 on Enterprise.

Output covers FBX, BVH, GLB and MP4, plus DMPE on Professional plans and above, along with JPG, PNG and GIF for poses. That covers Blender, Maya, Unity, Unreal Engine, iClone and Roblox workflows, so DeepMotion slots into an existing pipeline instead of replacing it. Camera angles, environment backgrounds and transparent image export are available for the video and pose outputs.

Every job consumes credits, and the Free Animation Credit Program lets you earn up to 100% back by labeling your own uploaded videos with text descriptions or by correcting animations in the Rotoscope Pose Editor. It's an unusual model, and it's effectively paid work in exchange for platform time. Heavy users on the Studio plan get unlimited credits, with the first 7,200 each month processed at the highest priority. Credits reset monthly and don't carry over.
