Short answer: yes, AI motion capture is genuinely free to start — but “free” means different things across tools. Some give you browser capture with monthly credits, some give you unlimited learning with limited export, and one is entirely open-source. This guide breaks down what each free tier actually includes, where the limits bite, and which free option fits your project.

Why AI mocap is free at all
Two forces made it happen. Pose-estimation AI got good enough that a single camera can reconstruct full-body motion, and a crowded market pushed vendors to offer free tiers to win users. So today you can capture, refine and export motion without paying — as long as you understand each tool’s boundaries.
What each free tier actually gives you
QuickMagic — free browser capture with credits
QuickMagic’s free plan lets you capture single-camera video (and text-to-motion) in the browser, with monthly credits and FBX export. It’s the quickest way to turn a phone clip into a rigged animation. Where the free tier limits you: clip length, monthly credit count, and the full range of export formats (BVH, Mixamo, Unreal presets and more) that unlock on paid plans. For testing real footage and shipping short animations, the free plan does the job.
Cascadeur — free tier with no time limit
Cascadeur’s free tier has no time limit and covers the core AI features — AutoPhysics, AutoPosing, rigging and cleanup — which makes it the best free way to refine mocap. The limits: it’s intended for learning and non-commercial use, and full export formats plus unrestricted commercial rights come with the Indie and Pro tiers (whose annual plans convert to a perpetual licence after a year).
Rokoko Vision — free web capture
Rokoko Vision captures from a webcam or uploaded video for free and exports FBX/BVH, with retargeting available in Rokoko Studio. A clean, no-cost solve if you’re already in the Rokoko ecosystem.
Plask — freemium browser credits
Plask offers browser-based capture on a freemium model with daily/monthly credits, exporting GLB/FBX/BVH — good for collaborative, no-install workflows.
FreeMoCap — 100% free and open-source
FreeMoCap has no paywall anywhere. It’s a multi-camera, open-source project, so the “cost” is setup and technical effort rather than money — ideal for tinkerers, students and researchers.
The catches to watch for
Before you build a project on a free tier, check these:
- Clip length and credits. Browser tools cap how much you can capture per month for free.
- Export formats. FBX is usually available free; specialised formats (BVH, VMD, engine presets) may be paid.
- Commercial rights. A tool can be free to use while still requiring a paid tier to sell your output — Cascadeur is the clearest example.
- Watermarks. Some tools watermark free exports; confirm on the pricing page (this is exactly why the affiliate links here send you to live terms).
- Cleanup is on you. Free single-camera capture floats and slides; budget a cleanup pass.
Because free tiers change often, always confirm the current limits on each tool’s own pricing page.
Which free AI mocap should you pick?
- Fastest free result: QuickMagic — video in, FBX out, in the browser.
- Best free cleanup and realism: Cascadeur — as a second step after capture.
- Best free web solve in an ecosystem: Rokoko Vision.
- Zero-budget, fully open: FreeMoCap.
For most people the winning move isn’t one tool — it’s a free pipeline: capture in QuickMagic, clean up in Cascadeur, finish in Blender or Unreal. Both halves are free to start, so you can run a whole clip through before spending anything.
FAQ
Is AI motion capture free?
Yes. QuickMagic and Rokoko Vision offer free browser capture, Cascadeur’s free tier covers cleanup with no time limit, and FreeMoCap is fully open-source.
What’s the catch with free AI mocap?
Usually clip/credit limits, a narrower set of export formats, and separate paid tiers for commercial use. Free single-camera capture also needs a cleanup pass.
Is there a totally free option with no limits?
FreeMoCap is fully free and open-source; the trade-off is more setup than the browser tools.
Which free AI mocap is best for beginners?
QuickMagic — it produces usable motion in minutes with nothing to install.
