Ffmpeg Skill

Ffmpeg Skill is an agent skill that gives coding agents a local video editor powered by FFmpeg.

Ffmpeg skill is an agent skill for Claude Code, Cursor, Codex, and other agents that read SKILL.md. It teaches the agent a fixed workflow of probing, lossless editing, checking, and verifying, and ships 42 tools that perform the actual work using FFmpeg and FFprobe. Every tool is callable as an MCP tool and is described by a machine-readable contract derived from its argparse parser. The engine operates entirely locally with no cloud dependencies, API keys, or Python package requirements beyond the standard library. It handles tasks such as cutting, joining, silence removal, aspect fitting, captions, overlays, HDR to SDR conversion, audio cleanup, multicam, loudness control, and batch rendering.
