cinematic-motion-language

cinematic-motion-language is a skill for Claude Code, Codex from alecs5am/ralphy. It costs 60 tokens per session (1,701 once invoked), scanned A, original, Apache-2.0.

A language guide for writing precise prompts for generated video, covering the camera, movement, timing, atmosphere, and physical behavior.

In plain words
What is it for?
Use it to specify camera movement, motion speed, scene sequence, constraints, and negative instructions for video prompts.
Why use it?
It replaces vague descriptions with concrete instructions so generated motion is more predictable.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

cinematic-motion-language scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Cinematic Motion Language

Purpose

This skill provides the five-pillar language system for constructing video prompts with cinematic precision. Apply it to any video generation task — atmosphere shots, product reveals, character scenes, abstract motion, sacred/spiritual visuals, or any brief where imprecise language would produce unpredictable results.

The core principle: the model understands physics, geometry, sequence, and constraint — not adjectives. Replace every vague descriptor with a physical analogy, spatial coordinate, temporal sequence, or hard rule.

The Five Pillars

    1. Camera Contract

State the camera's behavior as a hard rule before describing anything else. The model treats the camera as a character — define it or it will improvise.

Examples:

  • "Static locked-off camera. Zero movement. No pan, no zoom, no dolly, no shake."
  • "Slow push-in only — 10% scale change over the full duration."
  • "Single handheld drift, slight organic sway, no cuts."
  • Always reinforce camera rules in the negative prompt as well.

2. Motion Physics Anchor

Give every moving element a speed reference from the physical world, not an adjective. Pair physical analogies with time-anchored measurements for maximum precision.

Speed analogy examples:

  • "like dust suspended in honey"
  • "like embers floating in still air"
  • "like smoke through a cathedral at dawn"
  • "like the surface of a lake disturbed by a single drop"

Time-anchored measurements:

  • "one full revolution across the entire 10-second clip"
  • "roughly 6 degrees per second"
  • "the pace of a clock's hour hand — imperceptibly slow"
  • "travels the full arc in 8 seconds with no pause"
  • Never use "slow", "fast", "gentle", "subtle" alone — always anchor to physics or time.

3. Spatial Zoning

Divide the frame into named regions and assign explicit rules to each. This prevents the model from filling empty space with invented content.

Region naming conventions:

  • "Left third / center third / right third"
  • "Foreground plane / midground / background"
  • "Upper half / lower half"
  • "Right two-thirds / left void"
