 "title": "Mix narration, music, and effects into one finished video",
 "page_title": "How to mix narration, music, and effects into one finished video with Open Edit",
 "summary": "Build one loudness-levelled audio track from many pieces and mux it onto a render.",
 "who": "A content producer with separate narration, music, and sound effects who needs one finished file.",
 "problem": "Balancing several audio pieces by hand is slow, and voices get buried under music.",
 "outcome": "A final MP4 with a mixed audio track, with music ducked under the voice and levelled to -14 LUFS.",
 "steps": [
  "Place the narration, music, and effects pieces in the run folder and set the mix spec for the run.",
  "Run `npx @veedstudio/openedit-cli mix-audio runs/<run>` to build the mixed track. (inferred, check the README)",
  "Run `npx @veedstudio/openedit-cli mux-audio --video runs/<run>/out.mp4 --audio runs/<run>/audio/mix.m4a --out runs/<run>/final.mp4` to combine the audio and video. (inferred, check the README)"
 ],
 "agent_prompt": "In the veedstudio/open-edit repo, run mix-audio on the run folder <run>, then mux-audio onto the silent render. Expect final.mp4 with the mixed audio. Verify from the command output which loudness correction ran before you report success.",

 "difficulty": "Intermediate",
 "time": "30 minutes",
 "basis": "readme",
 "caveat": "The README says mix-audio builds the track from the run's mix spec, so the spec must already describe the pieces before the command runs.",

  "FFmpeg, which install-ffmpeg can find or download",
  "A VEED login for hosted transcription and the VEED editor handoff",
  "A fal key (FAL_KEY) only for fal-billed models, background removal with --fal or --fast, and lipsync"
