How to render inserts from audio on the command line with Kilnframe

Build Kilnframe from source and render an animated insert, stills and a sound effects mix from a WAV on the command line.

Short answer: Clone github.com/erhanmeydan/kilnframe and run pnpm install then pnpm build; then export the speech segment you want as part.wav; run node packages/core/dist/cli.js run --audio part.wav --style kil-lacivert --fps 30000/1001 --size 1920x1080 --out out/first. All steps.

Who it is forA developer automating explainer clips for many videos who wants the renderer without opening an editor.

The problemClicking through an editor panel for every clip does not scale.

The outcomeAn out/ folder with insert.mp4, preview.mp4, sfx_mix.wav, stills, plan.json and transcript.json.

What you need first

  • Adobe Premiere Pro or DaVinci Resolve Studio
  • pnpm and Node to build from source

Steps

  1. Clone github.com/erhanmeydan/kilnframe and run pnpm install then pnpm build
  2. Export the speech segment you want as part.wav
  3. Run node packages/core/dist/cli.js run --audio part.wav --style kil-lacivert --fps 30000/1001 --size 1920x1080 --out out/first
  4. Open out/first and check insert.mp4, preview.mp4 and plan.json
  5. Run pnpm check after any change (typecheck, lint, format and tests)

Prompt for your agent

Build kilnframe and render an insert from <wav> with style <style> at 1920x1080 into out/<name>. Confirm insert.mp4 and sfx_mix.wav exist and report the scene count from plan.json.

Caveat. You still connect an AI provider for planning; only the transcript, scene plan, style text and a few small stills are sent to it.
