Remotion Multimedia

Before you start: read this whole install prompt, tell me in a few lines what this skill does and what installing it involves, and wait for my go-ahead before you do anything else. Prerequisites — None to install this skill — no account, no key, no payment, and no executable code in its folder. Licence note: no licence was found anywhere in the upstream repository at the pinned commit. At use time it relies on the Mediabunny library in your own project (in the browser, Node.js or Bun) to read media files you point it at. Install "Remotion Multimedia" for me. It is a compact Mediabunny reference: Mediabunny is a multimedia library for dealing with audio and video in the browser, and the main file points to a compact overview on mediabunny.dev and routes to three companion guides — getting the duration of an audio file in seconds, getting the width and height of a video file, and getting the duration of a video file in seconds — each showing the Mediabunny Input API reading a media source (a URL, a Remotion staticFile(), a file path in Node.js/Bun, or a Blob). Its folder holds the main SKILL.md, those three companion guides, its agents/openai.yaml policy file and its icon. Repository: https://github.com/remotion-dev/skills (the skill is the whole skills/remotion-multimedia/ folder at the pinned commit: SKILL.md plus 5 companion files, 6 files in total) Pinned version: install the code at commit 6c67adcd9cdbe6eb84d76342da89b225f9161cb2 exactly. Do not substitute a newer version. If this commit is unreachable, stop and tell me. 1. Clone https://github.com/remotion-dev/skills into a temporary folder, check out commit 6c67adcd9cdbe6eb84d76342da89b225f9161cb2, and copy the skills/remotion-multimedia/ folder from that checkout. Then compare every file in the folder with the fingerprints recorded for this listing on 2026-10-22: [FINGERPRINTS] - SKILL.md: SHA-256 259db7738731b3cce6183994688f2472088ae3ac46b5870d1e039a8900bff28c - agents/openai.yaml: SHA-256 74e07a383bbf02808320ede199873d00a5fc976cb99d407056456b9abdfb0cb7 - assets/remotion-icon.svg: SHA-256 5007669bd0555b0f4565b4e7176fa191310ab0039b2ed09d867a9270f5b0ce58 - get-audio-duration.md: SHA-256 53b2e2ff232cae14ff9c0f7bb3ddf95c6137f7f1804cdaf50f7fe742befe0fd0 - get-video-dimensions.md: SHA-256 9d4cd07f11ce8fabda258b4d826e7c9b3d6827e87ee036a2c4c8a7a5aca7db76 - get-video-duration.md: SHA-256 6df955602cf7fb591ecb3f529fa9740d26ec1a4893a816aa08ea9b780379a8a0 If a file does not match, it changed since the listing was prepared: do not install it yet, tell me what you found and let me decide. 2. Read SKILL.md in full, and tell me in plain words: what the skill does when used, what it connects to, whether it reads or sends any personal information or credentials, and anything that seems unusual. Stop on any red flag and tell me before going further. Confirm these points from the files: - The skill folder holds 6 files only: the 705-byte SKILL.md, the 3 Mediabunny companion guides (get-audio-duration.md, get-video-dimensions.md, get-video-duration.md), agents/openai.yaml and the icon. There is no script and no other code in it. - Nothing is sent anywhere during installation itself; the only download at install time is the skill folder from GitHub at the pinned commit. The SKILL.md links to an overview page on mediabunny.dev — that link is documentation referenced at use time, not something fetched during installation. - At use time, Mediabunny reads only the media sources I point it at (a URL I give, a file in my project via staticFile() or a file path, or a Blob) and computes duration or dimensions locally in the browser, Node.js or Bun environment of my project. No credentials are read and no media is sent to any third-party service by the guides. - Do not read any media file of mine, do not install Mediabunny, and do not use the skill in any way during this install: using it is a separate step that only starts when I ask for it later. 3. When I say "yes, install", install it as a skill: copy the whole remotion-multimedia folder into the agent's skills directory, in a folder named exactly "remotion-multimedia", keeping its 6 files in their original relative layout (SKILL.md at its root). 4. Verify with no network calls: frontmatter valid (name: remotion-multimedia), the 6 files in place with matching fingerprints. Do not run anything from the folder and do not use the skill to verify. 5. Report what was installed, where, and what I still need to do myself (for example: that at use time it works through the Mediabunny library in my own project on media sources I provide, and that the companion router remotion-best-practices also covers this skill). GitHub is optional: if I have a GitHub account or the gh CLI, you may use it; otherwise public access is fine. Never require it unless it's in the prerequisites above. Rules: don't touch anything outside the temp folder and the install target. If anything looks off, stop and ask me.
