MovementModeler turns everyday video into clean, accurate human motion—fully on device. Visualize movement using stick figures, capsule rigs, or sprite-based rigs. Export motion as MP4 videos or BODY-25 JSON for analysis, research, and ML pipelines. MovementModeler converts ordinary video into precise motion visualizations using fast, fully on-device processing. Built for creators, athletes, coaches, researchers, and computer-vision practitioners, it provides a straightforward way to extract, review, and export human motion—without accounts, cloud uploads, or privacy trade-offs. Load a video from your library and MovementModeler automatically generates a real-time motion preview for every detected person. Multi-person scenes are handled through persistent track identification, keeping individuals consistently labeled even during motion, occlusion, or crossing paths. Any combination of people can be isolated for preview or export, making it easy to focus on a single subject or compare movements side by side. Choose between multiple visualization styles—including classic stick figures, capsule rigs, and sprite-based rigs—to match your use case or aesthetic preference. Built-in refinement controls help clean up real-world motion artifacts in real time. Smooth jittery joints, stabilize motion, suppress low-confidence frames, and fine-tune joint continuity for both global playback and individual frames—all without modifying the underlying data. Playback matches the original video speed, with frame-accurate scrubbing for detailed inspection. For export, generate lightweight MP4 motion videos using your selected visualization style, or BODY-25 JSON keypoint data suitable for research, robotics, sports analysis, rehabilitation, animation, and machine-learning workflows. JSON exports include per-frame keypoints, confidence values, and stable multi-person track IDs—ready for downstream analysis or model training. ## Key features - On-device video to motion processing - Multiple visualization styles (stick figures, rigs) - Export as MP4 or BODY-25 JSON - Multi-person tracking and isolation - Real-time motion refinement controls - Frame-accurate scrubbing ## Frequently asked questions about MovementModeler ### What is MovementModeler?

Metadata is embedded directly in the JSON for seamless pipeline integration. ### 2.3 — 2026-03-23 Pinned Preview The motion preview now stays visible at the top of the screen while you adjust controls. No more scrolling back up to see your changes — tweak sliders and watch the figure update in real time. Live Track Persistence MAX_MISSES now updates instantly. Adjust how long a person can disappear before losing their ID without reloading the video — tracking re-runs in the background the moment you change the value. Cleaner Architecture Under-the-hood refactor for stability and future features. Faster, leaner, fewer bugs. ### 2.2.1 — 2025-12-31 Performance enhancements and minor bug fixes. ### 2.2 — 2025-12-29 Bug fixes and minor preview improvements, including clearer frame and tracking indicators. ### 2.1 — 2025-12-27 Tap people directly in the preview to select tracks. Touch controls make it easier to focus on specific subjects while reviewing motion data. ## More apps by AARON C SMITH - [Markdown SSH Terminal](https://appshunter.io/ios/app/markdown-ssh-terminal/id6785126823) All apps by AARON C SMITH: https://appshunter.io/developer/1857852627 ## Related topics [motion capture ai](https://appshunter.io/ios/topics/motion-capture-ai) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
