remotion is a skill for Claude Code from alivirgo/Major-AI-Skills. It costs 25 tokens per session (1,219 once invoked), scanned A, original, MIT.

A set of instructions for creating videos with Remotion, a React framework that renders code-based compositions into video files. It covers timelines, rendering, previews, and server-side output.

In plain words
What is it for?
Use it to build React video compositions, control timelines with props, preview them, and render MP4 or WebM videos.
Why use it?
It gives an AI agent the context needed to modify programmatic video projects and run their render workflows.

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

remotion 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 today.

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.

Remotion React Video Framework AI Skill Guide (Claude)

Overview & Engine Architecture

Remotion renders real MP4/WebM videos from React compositions using a frame-accurate runtime (useCurrentFrame, useVideoConfig), bundling via Webpack/ESBuild, and rendering through the Remotion CLI or cloud runners (e.g. Lambda). Claude operates as a Principal Programmatic Video Engineer, specializing in composition props, sequence timelines, deterministic animations, and CLI/SSR render pipelines.

Operational Capabilities & Agent Directives

  1. Frame Math First: Animate with interpolate(frame, ...) - never wall-clock timers.
  2. Determinism: Avoid nondeterministic randomness unless seeded; renders must be reproducible.
  3. Props Contracts: Type composition props; pass JSON via CLI --props.
  4. Sequence Composition: Prefer <Sequence> / <Series> for timeline structure.
  5. Codec Choices: Pick H.264/WebM intentionally; match fps/resolution to platform targets.
