Dear users，


Thank you for your continuous support and love for our product! Due to many users expressing confusion on how to get Motion Capture for 3D or 2D animation and we immediately worked overtime to provide tutorials for everyone! Without further delay, let us proceed to start.

Professional motion capture used to require a studio, a thousand-dollar suit, and a crew. Not anymore. With QuickMagic AI, your smartphone is all you need to generate high-quality motion capture data for both 3D character animation (Maya, Blender, Unreal Engine) and 2D animation (Cartoon Animator). Record a video on your phone, upload it to QuickMagic, and the AI turns your performance into ready-to-use animation data — completely free to start.



How Phone-to-Mocap Works


QuickMagic uses AI-powered computer vision to analyze standard video frames from your smartphone and extract 3D motion data. Unlike traditional optical mocap — which requires reflective markers, multiple cameras, and a controlled studio — QuickMagic works with any video you record on your phone.


The process is remarkably simple:




The AI detects body joints, tracks limb movement across frames, estimates 3D depth from 2D footage, and reconstructs a full skeleton hierarchy with rotation data. The result is a keyframe-animated skeleton you can import directly into any major 3D or 2D animation tool.



3D Animation Pipeline: Phone to Character


For 3D projects — whether you're working in Maya, Blender, Unreal Engine, Unity, or Cinema 4D — here's the complete workflow from your phone to a polished animation:

2D Animation Pipeline: Phone to Cartoon Animator


QuickMagic isn't just for 3D. If you work in 2D animation, Reallusion Cartoon Animator can accept QuickMagic's motion data and drive 2D character Rigs directly — turning a phone video into fully animated 2D characters in minutes.

Compatible Animation Software


QuickMagic exports standard FBX and BVH formats, making it compatible with virtually every animation tool on the market:


3D Animation


  • Autodesk Maya — Import FBX, retarget to custom Rigs, refinish in Graph Editor
  • Blender — Free and open-source, full FBX support with auto-rig retargeting
  • Unreal Engine 5 — Direct FBX import, IK Retargeter for MetaHuman and custom skeletons
  • Unity — FBX import with Humanoid Avatar retargeting system
  • Cinema 4D — FBX import with Character Object workflow
  • 3ds Max — FBX import, CAT or Biped retargeting, curve cleanup tools

2D Animation


  • Reallusion Cartoon Animator — Direct 3D motion import, bone-to-bone 2D mapping
  • Moho (Anime Studio) — BVH import for 2D bone-driven characters
  • Spine — Can accept external motion data through scripting



Tips for the Best Phone Mocap Results


  • Lighting is everything: QuickMagic's AI relies on clear silhouettes. Shoot in bright, even front-lighting. Avoid strong backlight (windows behind you) and harsh shadows that obscure limb boundaries.
  • Stabilize your phone: Use a tripod or prop your phone against a stable surface. Handheld footage introduces camera shake that the AI must compensate for, reducing accuracy.
  • Wear fitted clothing: Baggy clothes make it harder for the AI to detect joint positions. Solid colors work better than busy patterns.
  • Frame for your animation: For full-body capture, the camera should see you from head to toe. For upper-body performances, frame from waist up. Leave some margin around the frame for arm and head movement.
  • Record at 60fps for action: Fast movements (kicks, jumps, spins) benefit from higher frame rates. 60fps gives the AI more data points to work with and produces smoother results.
  • Start and end with a T-pose: Hold a T-pose for 1 second at the start and end of your clip. This helps QuickMagic calibrate bone lengths and makes retargeting easier in your animation software.



Frequently Asked Questions


Can I really do motion capture with just my phone?


Yes. QuickMagic AI uses computer vision to extract motion capture data from standard smartphone video — no markers, suits, or special cameras required. Your phone records the video, QuickMagic's AI analyzes it to generate 3D skeletal motion data, and you export the result as FBX or BVH for use in any 3D or 2D animation software. The free tier lets you capture up to 30 seconds of video per clip.


Is QuickMagic AI motion capture really free?


QuickMagic offers a free tier that includes motion capture from video uploads with standard resolution and processing speed. The free plan is sufficient for indie creators, students, and hobbyists to create high-quality motion capture from phone video. Paid plans unlock higher resolution capture, longer video processing, batch exports, and commercial usage rights. Check the QuickMagic pricing page for details.


What 2D animation software works with QuickMagic phone mocap?


QuickMagic phone-based motion capture works with Reallusion Cartoon Animator for 2D character animation. The captured bone motion data maps directly onto Cartoon Animator's 2D bone Rig system via the 3D Motion Converter. Other 2D animation software that supports external motion data import — such as Moho (Anime Studio) or Spine — may work with BVH exports from QuickMagic, though some manual configuration may be required.


What phone do I need for AI motion capture?


Any modern smartphone — iPhone 8 or newer, or any Android phone released from 2019 onwards — works with QuickMagic AI motion capture. The essential requirements are a working camera that records at 720p minimum (1080p recommended), and the ability to transfer video files to your computer. No special apps, ARKit, or depth sensors are required — QuickMagic processes standard video files through its cloud-based AI pipeline.



How accurate is phone-based mocap compared to professional systems?


QuickMagic AI phone-based mocap achieves good accuracy for body motion — typically within 2–5cm of optical mocap for most movements, which is sufficient for game development, previsualization, indie animation, YouTube, and social media content. For Hollywood VFX requiring sub-millimeter precision, professional optical systems still lead. However, the gap is narrowing rapidly as QuickMagic continues to train its AI on larger datasets.
