Mediabunny is a library for audio and video in the browser. The skill gives the agent three small how-to files, one for audio duration, one for video dimensions and one for video duration. It also links Mediabunny's compact overview at mediabunny.dev/llms.txt.

The audio and video duration guides say the code works in the browser, Node.js and Bun. The skill bundles no scripts, and neither SKILL.md nor the guides mention an API key.

Good for

Remotion developers who set composition length or size from a media file
Anyone using Mediabunny for browser audio and video work

Questions

How do I install remotion-multimedia?

Use the install box above. The Remotion README also lists npx skills add remotion-dev/skills for the whole set and a GitHub CLI route. The remotion-best-practices skill covers all the others if you are unsure which one to pick.

Does it work in Claude Code, Claude app or Codex?

The Remotion README says its skills are for agents like Claude Code, Codex, Kimi Code and Cursor. It does not document the Claude app. This skill also ships a small Codex display file.

What does remotion-multimedia do?

It teaches the agent three Mediabunny tasks: audio duration, video duration and video dimensions.

Does it need an API key?

SKILL.md and its guides mention no key.

Is it safe?

It is text guides with code samples and bundles no scripts. The code the agent writes from them runs in your project like any other code, and the samples read media files from a URL or, in Node.js and Bun, from disk.

Does it cover Mediabunny conversion or editing?

Not in the skill. It lists only the three lookup guides and links to the Mediabunny overview for anything else.
