Extract key frames (I-frames) from video files using FFmpeg CLI. Use this skill whenever you need to pull out keyframes, thumbnails, or important frames from MP4, MKV, AVI, or other video formats for analysis, previews, or processing.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'ffmpeg-extraction' ] || [ -L ~/.agents/skills/'ffmpeg-extraction' ]; then echo 'A skill folder named ffmpeg-extraction already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/cxcscmu/SkillLearnBench' "$d" && git -C "$d" checkout --quiet '726e1f79b96b0cb3d729d0e55a1c847e0b5353ae' -- 'skills/b4-skill-creator-gemini-3.1-pro-preview/video-object-counting/ffmpeg-extraction' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/b4-skill-creator-gemini-3.1-pro-preview/video-object-counting/ffmpeg-extraction' ~/.agents/skills/'ffmpeg-extraction' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'ffmpeg-extraction' ~/.claude/skills/'ffmpeg-extraction' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
