What remotion-multimedia does

remotion-multimedia gives Codex focused guidance for using Mediabunny, a browser library for audio and video work. Its documented tasks cover three values: audio length in seconds, video length in seconds, and a video's width and height.

The skill includes separate guidance files named get-audio-duration.md, get-video-dimensions.md, and get-video-duration.md. Each one covers the matching measurement. It does not describe editing or encoding, so those workflows fall outside this skill's stated scope.

What it helps with

  • read an audio file's duration in seconds
  • check a video's width and height
  • measure the duration of a video file
  • inspect media metadata through Mediabunny

Example prompts for the agent

  • Use Mediabunny to find the audio file's duration and report it in seconds.
