Runs ffmpeg and ffprobe directly on your local machine for video editing tasks. No wrapper scripts or abstractions, just the raw commands you'd run in terminal anyway. Useful when you need Claude to help trim clips, extract audio, convert formats, or probe video metadata without bouncing through an API. The skill comes from HeyGen and requires you to have ffmpeg installed locally (straightforward on macOS with Homebrew or Ubuntu with apt). It's basically giving Claude direct access to the Swiss Army knife of video processing, which is helpful if you're already comfortable with ffmpeg but want to prototype edits conversationally.
