/video-promo

Generate a promo video plan from a project's PRD. Produces a 30-45 second video script with shot-by-shot storyboard. Detects Montage-tool or Remotion in the project and outputs compatible config when found.

MCP Tools (use if available)

• project_code_search(query, project) — find UI components, screens, features to showcase
• project_info(name) — get project stack and details
• kb_search(query) — find video production methodology

If MCP tools are not available, fall back to Glob + Grep + Read.

Steps

1. Parse project from $ARGUMENTS.

- Read PRD (docs/prd.md), README, or CLAUDE.md for product info. - If empty: ask via AskUserQuestion.

1. Detect video tooling in the project:

- Check package.json for remotion, @remotion/cli → Remotion project - Check for montage.config.*, pnpm montage → Montage-tool project - Check for ffmpeg usage in scripts → FFmpeg pipeline - If none found: output plain storyboard (no specific tooling config)

1. Extract key screens/features to showcase:

- If MCP available: project_code_search("main screen OR hero OR dashboard", project) — find showcase-worthy UI - Otherwise: Glob for screenshots, mockups, or UI component files - Read PRD for top 3-5 features to demonstrate

1. Forced reasoning — video strategy:

Before scripting, write out: - Goal: What should the viewer DO after watching? (download, sign up, visit) - Hook type: Question? Surprising stat? Pain point? Bold claim? - Demo moments: 3 key product moments to show on screen - Emotion arc: Frustration → Discovery → Relief/Delight

1. Generate video script (30-45 seconds):

   ## Video Script: {Project Name}

   **Duration:** 30-45 seconds
   **Format:** Vertical (9:16) for Reels/TikTok/Shorts
   **Style:** Screen recording + text overlays

   ### HOOK (0:00-0:03) — 3 seconds
   **Audio:** "{hook line — question or bold statement}"
   **Visual:** {what appears on screen — text overlay on gradient/blurred BG}

   ### PROBLEM (0:03-0:10) — 7 seconds
   **Audio:** "{describe the pain in user's words}"
   **Visual:** {show the frustrating current state — competitor UX, manual process, etc.}

   ### DEMO (0:10-0:25) — 15 seconds
   **Audio:** "{narrate what the product does}"
   **Visual:**
   - Shot 1 (5s): {first feature demo — screen recording}
   - Shot 2 (5s): {second feature demo}
   - Shot 3 (5s): {wow moment — the key differentiator}

   ### CTA (0:25-0:30) — 5 seconds
   **Audio:** "{call to action}"
   **Visual:** {product logo + URL + download badge}

1. Generate tooling config (if applicable):

### If Remotion detected:

   ## Remotion Component Spec

   Component: `PromoVideo.tsx`
   Duration: 900 frames (30fps × 30s)

   Sequences:
   - HookSequence (0-90): Text animation on gradient
   - ProblemSequence (90-300): Screen recording import
   - DemoSequence (300-750): 3 feature recordings with transitions
   - CTASequence (750-900): Logo + URL fade in

   Assets needed:
   - screen-recording-problem.mp4
   - screen-recording-feature-1.mp4
   - screen-recording-feature-2.mp4
   - screen-recording-feature-3.mp4
   - logo.png
   - background-music.mp3

### If montage tool detected:

   ## Montage Config

   Clips:
   - problem-clip.mp4 (7s)
   - demo-feature-1.mp4 (5s)
   - demo-feature-2.mp4 (5s)
   - demo-wow-moment.mp4 (5s)

   Music: {suggest genre/BPM for beat-sync}
   Transitions: crossfade (0.5s)
   Text overlays: hook, CTA

1. Write plan to docs/video-promo.md:

   # Video Promo Plan: {Project Name}

   **Generated:** {YYYY-MM-DD}
   **Duration:** 30-45 seconds
   **Format:** Vertical 9:16
   **Tooling:** {Remotion / Montage-tool / Manual}

   ## Script
   {full script from step 5}

   ## Assets Checklist
   - [ ] Screen recording: {feature 1}
   - [ ] Screen recording: {feature 2}
   - [ ] Screen recording: {wow moment}
   - [ ] Logo (transparent PNG)
   - [ ] Background music (royalty-free, upbeat)

   ## Tooling Config
   {config from step 6, or "Record manually and edit in CapCut/iMovie"}

1. Output summary — script overview, assets needed, suggested next steps.

Notes

• Script assumes screen recording as primary footage — no actor needed
• For iOS apps: use Simulator recording or device mirroring
• For web: use browser screen recording
• Music: suggest royalty-free sources (Artlist, Epidemic Sound, YouTube Audio Library)
• This skill generates the PLAN — actual video rendering is manual or via Montage-tool/Remotion

Common Issues

No video tooling detected

Cause: Project doesn't use Remotion or Montage-tool. Fix: Skill outputs plain storyboard by default. Record manually and edit in CapCut/iMovie, or add Remotion to the project.

Script too long for short-form video

Cause: Too many features to showcase. Fix: Pick TOP 3 features only. 30-45 seconds = ~75-100 words of narration. Less is more.

No screenshots or UI to record

Cause: Product not built yet or no visual interface. Fix: Use mockups, wireframes, or describe intended visuals in the storyboard. Record after MVP is built.
