Open Mocap vs Plask Motion

Open Mocap is a free, open-source Blender add-on for AI-powered motion capture. It captures full-body movement offline from video and tracks hands both offline and in real time. Captured motion can be retargeted to a 3D character rig, with the workflow staying inside Blender and requiring no external software. The maker describes it for artists, animators, and researchers seeking motion capture in Blender. The add-on runs on Linux, macOS, and Windows, but compatibility is limited to Blender 4.0.0 and earlier. Recommended compatible components include Blender’s bundled Python 3.10, MediaPipe 0.10.14, OpenCV-Python 4.11.0.86, and CVZone 1.6.1; newer versions may cause runtime errors. The project uses the MIT License and welcomes bug reports, performance improvements, feature work, documentation contributions, and pull requests. Help is available by emailing [email protected] or opening a GitHub issue. There is no facial tracking or API access.

Plask Motion turns video into 3D animation using AI motion capture, without suits or sensors. Its single-camera capture extracts body movement that users can apply to an imported 3D character. MMD and VRM models support blinking and physics. The product also renders video with automated camera and lighting controls and customizable effects, and exports FBX, GLB, and BVH. Listed workflows cover Blender, Unreal Engine 4 and 5, iClone, After Effects, MetaHuman, VRoid, Cinema 4D, and Ready Player Me. Scene sharing and realtime collaboration are listed for all three plans. Plask recommends horizontal video at 720p or higher; it accepts MP4 and WebM files up to 100 MB and from 3 seconds to 5 minutes long. Multi-person capture is recommended for fewer than 10 people and limited to under one minute and 1,800 frames. The software recognizes human forms, not non-human objects for animation. A free plan is listed; Standard and Pro offer a 7-day trial. Standard is $216 a year and Pro is $600 a year.
