FFBlueprint
A FFmpeg Command Builder

// all encoders · all options · one line

Build a ready-to-run FFmpeg command: pick your settings, then copy the generated command line below into your terminal. Nothing is uploaded or converted here — the tool only writes the command.

Requirements: FFmpeg installed (a current full build — hardware encoders and AV1 need a recent one) · FFprobe for the optional Analyze Streams and chapter helpers · any modern browser, fully offline.
