demo-promolisted

Turn a raw screen-recording / product demo into a polished, branded LANDSCAPE promo video that drives engagement. Pipeline — cut dead air, color-grade, hook card, persistent rotating TOP purpose-strap (Mike Chang style), image PiP inserts (show the actual artifact built), platform/feature chip strip, benefit callout ("this saves you HOURS"), outro CTA card, British/American AI voiceover (ElevenLabs) + sidechain-ducked cinematic BGM. Whisper-syncs overlays to the narration. Distilled from the SkynetLabs "Claude Code auto-publishes content" promo (2026-05-29). Trigger when user says "polish this demo", "make a promo from this recording", "edit this screen recording", "add hook + strap + voiceover", "/demo-promo", "Mike Chang style heading", or pastes a raw .mkv/.mp4 screencast asking to make it engaging.

# Demo-Promo — Screencast → Branded Engagement Promo End-to-end pipeline that turns a long raw screen-recording into a tight, branded, voiced promo. **Landscape 16:9** (LI / YouTube / FB / X). For 9:16 reels use `reel-studio` instead. Proven on: `Videos/2026-05-29_claude-autopublish_FINAL.mp4` (8:12 raw → 1:52 promo). ## When to use Raw demo/screencast + user wants it "polished", "perfect", "engaging", with hook / heading / voiceover / music. NOT for talking-head vertical reels (→ reel-studio), NOT for static social cards (→ social-stack). ## The 6-phase pipeline 1. **Probe** raw video (ffprobe): res, fps, duration, codecs. 2. **Cut + grade** — trim dead air to the keeper segments, dissolve at joins, CLEAN color grade. → `*_POLISHED.mp4` (keep as backup; original audio). 3. **VO** — write ~200-260 word script narrating the demo → ElevenLabs TTS → loudnorm to stereo WAV. 4. **Sync** — faster-whisper transcribes the VO → segment timestamps → map overlays to narration beats. 5. **Overlays** — hook card + rotating top purpose-strap + image PiP inserts + chip strip + benefit callout + outro CTA card. 6. **Mix + mux** — continuous cinematic BGM (looped + dynaudnorm) sidechain-ducked under the VO; concat hook+main+outro; mux. → `*_FINAL.mp4`. `recipes/build_promo.py` is the runnable orchestrator — edit the CONFIG block at the top and run. It encodes every gotcha below. ## Engagement layer (why each element earns its place) - **Hook card (0-3s)** — pattern-interrupt headline
