Extract ordered still-image frames from local video files with FFmpeg, using a fixed FPS, an exact frame count, explicit timestamps, or every source frame; optionally remove a flat chroma-key background and emit timing metadata. Use for video-to-frame conversion, animation frame sampling, contact-sheet inputs, sprite animation source frames, dataset frames, thumbnail sequences, or any request to split MP4, WebM, MOV, MKV, AVI, or other FFmpeg-readable video into PNG, WebP, or JPEG images.

Works with any agent that supports SKILL.md skills.

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

if [ -e ~/.agents/skills/'slice-video-frames' ] || [ -L ~/.agents/skills/'slice-video-frames' ]; then echo 'A skill folder named slice-video-frames already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/Yuki001/game-dev-skills' "$d" && git -C "$d" checkout --quiet 'ef297c3b2e04c1000c9a1b9df88bc0296423abfb' -- 'skills/slice-video-frames' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/slice-video-frames' ~/.agents/skills/'slice-video-frames' && 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/'slice-video-frames' ~/.claude/skills/'slice-video-frames' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
