GATEWAY — load FIRST before composing any HyperFrames animation or video. The high-level motion law that makes a multi-scene video feel like ONE continuous camera move instead of a stack of independently-animated slides. Covers the vector law (how you exit determines how you enter, incl. the Z scale-sign rule), the film's current, carrier elements, causal motion, the Seam Gate (build-gate enforcement), the ban on idle wobble (motion must PERFORM, not breathe), stillness-before-climax, and the…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Motion Doctrine (Gateway) Read this before composing any animation. It decides WHAT happens at every seam and how every scene performs; the technique skills implement it. These rules supersede generic / upstream motion guidance. The failure this prevents: scenes authored in isolation — the eye's momentum dies at every cut, and scenes wobble in place between entry and exit. ## Route map | Decision (this skill) | Implementation skill | | -------------------------------------------------- | ------------------------------------------------------------------------------------------------- | | Seam transition choice + parameters + code | `cut-the-curve` §1–5 (the catalog) | | Text / element entry cascades | `cut-the-curve` §6 (waterfall entry) | | In-scene group repositioning (no cut) | `cut-the-curve` §7 (nudge curve) | …

How to install
mdr add heygen-com/hyperframes/motion-doctrine@sha256:d4d20aa33a577841The line at the top of this page pins the label git:20260910.8820a01, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
