The $15/Month Revolution in Motion Capture

Three years ago, convincing motion capture required a $50,000+ setup with specialized suits, markers, and dedicated capture volumes. Today, AI-powered markerless motion capture delivers 85-95% of that quality from a smartphone video—starting at $15/month.

For technical directors and animation supervisors evaluating these tools, the question isn't whether AI mocap is production-ready—it's which tool fits your pipeline. This guide breaks down the four leading platforms for game development workflows, with special attention to Unreal Engine 5 integration.

  • • Hand tracking less precise than DeepMotion
  • • Processing can be slow during peak hours
  • • Limited offline capability
  • • Export formats sometimes need cleanup

💡 Best For

Teams who value fast iteration and collaboration. Excellent for cinematics, dialogue sequences, and projects where facial performance matters alongside body motion.

Rokoko Vision

Free Option

Rokoko Vision is the free tier of Rokoko's AI mocap offering. While limited, it provides a legitimate entry point for testing AI mocap workflows before committing to paid solutions. You get 5 free video uploads per month.

✓ Strengths

  • • Completely free tier available
  • • Integrates with Rokoko ecosystem
  • • Direct Unreal Engine plugin
  • • Good for testing AI mocap workflows
  • • No credit card required

✗ Limitations

  • • Lower quality than paid alternatives
  • • Very limited monthly processing
  • • No hand tracking
  • • Basic face tracking only
  • • Watermarked exports on free tier

💡 Best For

Hobbyists, students, and studios evaluating whether AI mocap fits their workflow before investing in paid solutions. Also useful for very rough blocking and reference.

Best Mocap Workflow for Unreal Engine 5

Capture Reference Video

Record your actor with good lighting, minimal occlusion, and camera at waist height. For multi-view setups (Move AI), position cameras at 45° intervals.

Pro tip: Use 60fps minimum for fast movements. Solid contrasting background (green screen not required) improves tracking accuracy by 15-20%.

Process Through AI Mocap Tool

Upload to your chosen platform. Configure skeleton type (usually "Unreal Mannequin" or "Mixamo") for optimal retargeting later.

Export settings: FBX with baked keyframes, 30fps for cinematics, 60fps for gameplay animations. Enable root motion if your game uses it.

Import to Unreal Engine

Import FBX with "Import Animations" enabled. Use UE5's IK Retargeter to map the animation to your game skeleton.

IK Retargeter setup: Create IK Rig for both source skeleton (AI mocap output) and target skeleton (your character). Map bone chains, then create IK Retargeter asset.

Polish in Control Rig

Use UE5's Control Rig for final adjustments. Fix foot sliding, smooth transitions, and add secondary motion.

Common fixes: Ground contact (Two Bone IK solve), hand positions (FK adjustments), hip height correction (procedural offset).

📹 Need to Record Your Animations in Action?

Once your mocap animations are in Unreal Engine, capture them in-game for demos, trailers, or QA review. Runtime Video Recorder lets you record directly from UE5 with hardware acceleration—no performance impact.

Our Recommendations by Use Case

🎮

Indie Game Studios

Recommended: DeepMotion ($15/mo)

Best value for teams with limited animation budgets. The hand tracking alone justifies the cost for dialogue and interaction sequences.

Alternative: Plask if you prioritize face tracking and web-based collaboration.

🏢

AAA / Mid-Size Studios

Recommended: Move AI ($29+/mo)

Multi-camera support delivers quality that can stand alongside traditional mocap. Worth the premium for hero animations.

Alternative: Traditional mocap for hero characters, AI mocap for background NPCs and variations.

🎬

Game Cinematics

Recommended: Plask ($20/mo)

Built-in face tracking and the polished editing interface make it ideal for dialogue-heavy cutscenes.

Workflow tip: Combine with dedicated face capture (Live Link) for hero characters.

Rapid Prototyping

Recommended: Rokoko Vision (Free)

Free tier is perfect for blocking out animations and testing concepts before investing in proper mocap capture.

Upgrade path: Once validated, move to DeepMotion or Move AI for production quality.

AI Motion Capture Accuracy: The Real Numbers

85-90%

Basic locomotion (walk, run, jump)

80-85%

Complex actions (combat, sports)

70-80%

Subtle performance (acting, dialogue)

⚠️ Where AI Mocap Still Struggles

  • • Precise finger articulation (improving rapidly)
  • • Multi-person interaction with occlusion

Frequently Asked Questions

How much does AI motion capture cost in 2025?

AI motion capture tools now start at $15/month for basic plans. DeepMotion offers plans from $15/month, Plask starts at $20/month, and Move AI begins at $29/month. Free options like Rokoko Vision offer limited credits. Enterprise pricing typically runs $200-500/month for unlimited processing.

Which AI mocap tool is best for Unreal Engine integration?

Move AI and DeepMotion offer the best direct Unreal Engine integration with FBX export and retargeting support. Both support UE5's Control Rig and IK Retargeter. Plask requires additional processing for optimal UE5 results but offers excellent web-based previews.

Is AI motion capture accurate enough for AAA games?

AI mocap achieves 85-95% accuracy of traditional marker-based systems for most body movements. It excels at locomotion, combat, and dialogue scenes. However, precise finger tracking and subtle facial expressions still benefit from traditional mocap or manual polish for AAA quality standards.

What is markerless motion capture?

Markerless motion capture uses AI and computer vision to track human movement from regular video without requiring special suits, markers, or dedicated hardware. Tools like DeepMotion, Move AI, and Plask can extract animation data from smartphone or webcam footage.

Can I use AI motion capture for commercial game projects?

Yes, all major AI mocap platforms (DeepMotion, Move AI, Plask) include commercial usage rights in their paid plans. Free tiers typically have restrictions, so check licensing terms before using in released games. Most platforms require attribution only for free-tier usage.
