What it is
A skill containing FFmpeg recipes for short-form video: crop to 9:16, burn in captions, normalise audio, and concatenate clips. FFmpeg flags are the kind of thing models misremember, so a cookbook of working commands is more useful than free-form generation. The output is a file, not a timeline.
Install
Clone the repository, then copy the skill folder into your agent's skills directory — ~/.claude/skills/ for Claude Code. Skills are plain files: no build step, no daemon.

Read the SKILL.md before you install. A good skill states when it applies, what it must not do, and how to verify the result. A skill that only lists adjectives will change the agent's tone without improving its output — skip those.
