Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00065 | $0.05877 |
| Opus 5 | $0.00032 | $0.02939 |
| Sonnet 5 | $0.00013 | $0.01175 |
| Haiku 4.5 | $0.00006 | $0.00588 |
Grade A, and why
remotion-video-composition 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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 592 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Remotion video composition production
Use this skill when Remotion is the composition layer for a real video deliverable: generated-media explainers, product videos, social variants, data-driven videos, screen-demo composites, captioned talking-head recuts, or any render where React code, assets, captions, audio, and delivery metadata must become a reproducible video package.
This is a production skill, not just a coding recipe. Treat Remotion as the deterministic assembly and finishing engine around media that may have been generated elsewhere.
Source status and volatility
Facts below are based on primary sources verified on 2026-07-11 unless noted otherwise:
- Remotion documentation for composition properties, assets, static files, media components, renderer APIs, schemas, dynamic metadata, randomness, performance, captions, and licensing: https://www.remotion.dev/docs/
- FFmpeg official documentation for stream mapping, codecs, filters, and filtergraphs: https://ffmpeg.org/ffmpeg.html and https://ffmpeg.org/ffmpeg-filters.html
- W3C/WAI WCAG guidance for captions and flashing: https://www.w3.org/WAI/WCAG22/Understanding/captions-prerecorded.html and https://www.w3.org/WAI/WCAG22/Understanding/three-flashes-or-below-threshold.html
- W3C WebVTT specification for timed-text cues: https://www.w3.org/TR/webvtt1/
- C2PA specifications and Content Credentials guidance for provenance manifests: https://spec.c2pa.org/ and https://c2pa.org/
Volatile facts: Remotion package versions, API availability, licensing and pricing, cloud render limits, browser renderer status, package deprecations, social-platform delivery specs, caption file requirements, and AI/provider usage rights. Re-check those at production time and record the verification date in the project handoff.
Production stance
Remotion is strongest when the video can be expressed as deterministic React over a timeline:
- branded motion graphics;
- generated-image or generated-clip assembly;
- chart/stat/data videos;
- captioned narration;
- batch variants;
- programmatic product or screen-demo layouts;
- precise frame-based review exports.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

remotion-video-composition is a skill published in the GitHub repository calesthio/generative-media-skills (170 stars, last pushed 1mo ago), licensed MIT. It adds 65 tokens to every session and 5,877 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
