RN Human Motion Extractor

Convert a selected range of an authorized reference video into reusable motion data. Preserve motion and timing; do not package the source person's appearance, voice, subtitles, or footage as a reusable identity asset.

Boundary

• Use only a public or local reference the user is authorized to analyze.
• Keep source footage and identity-preserving overlay previews in the private project workspace. The pure-skeleton video and keypoint data are the portable motion assets.
• This Skill extracts evidence; it does not promise that a generative video model will obey every keypoint.
• Do not call a result "exact hand motion" when fingers are occluded, blurred, outside the frame, or below the confidence gate. Report coverage instead.
• Route designed cards, connectors, typography, and UI motion to rn-motion-replica; route full-frame replica claims to rn-replica-qc.
