Ad Render

/ad-render — The Video Producer

Turn a creative brief into rendered video ads. Uses Remotion to generate MP4 files in all major ad formats (vertical, square, landscape).

Chains naturally from /creative-brief → /ad-copy → /ad-render.

Prerequisites

• Node.js (v18+) — required for Remotion
• Brand config — run kai-config set brand.name "YourBrand" and set colors

Arguments

Required:

• archetype: problem-agitation | social-proof | product-demo | lifestyle

Optional:

• --format: vertical | square | landscape | all (default: all)
• --copy: JSON string or file path with ad copy fields (hook, problem, solution, cta)

Example: /ad-render problem-agitation Example: /ad-render social-proof --format vertical

The Skill

Step 1: Load Brand Tokens

Read brand configuration:

kai-config get brand.name
kai-config get brand.colors.primary

If brand is not configured, prompt user: "Set your brand first: kai-config set brand.name 'YourBrand' and kai-config set brand.colors.primary '#yourcolor'"

Step 2: Check for Ad Copy

Look for the most recent creative brief or ad copy in ~/.kai-marketing/briefs/. If ad copy fields are provided via --copy, use those. If neither exists, prompt user to run /ad-copy or /creative-brief first.

Extract from the copy:

• hook: The attention-grabbing first line
• problem: The pain point being addressed
• benefit: What the product solves
• stat: A proof point (number, percentage, result)
• cta: The call to action text

Step 3: Scaffold Remotion Project

Run:

kai-render scaffold --archetype {archetype} --format {format}

This creates a Remotion project at ~/.kai-marketing/renders/{date}/ with:

• src/config/brand.ts — Brand colors, fonts, assets from config
• src/config/scenes.json — Scene-by-scene composition config
• src/templates/ — Remotion composition templates
• package.json — Dependencies and render scripts

Display the scene breakdown:

VIDEO AD — {archetype} ({format})
═══════════════════════════════════

Brand: {name} | Colors: {primary} / {secondary}

Scene 1: HOOK (3.0s)
  Text: "{hook text}"
  Animation: scale
  Background: brand color

Scene 2: PROBLEM (4.0s)
  Text: "{problem text}"
  Animation: slide-up
  Background: gradient

Scene 3: AGITATE (3.0s)
  Text: "Sound familiar?"
  Animation: fade-in
  Background: gradient

Scene 4: CTA (3.0s)
  Text: "{cta}"
  Animation: spring
  Background: brand color

Total: 13.0s | Format: 1080x1920 (9:16)

Step 4: Install & Render

If Node.js is available:

cd ~/.kai-marketing/renders/{date}
npm install
npx remotion render src/Root.tsx {CompositionName} out/{format}.mp4

If Node.js is NOT available: "Node.js required for video rendering. Install: https://nodejs.org. The Remotion project has been scaffolded — you can render it on any machine with Node."

Step 5: Show Output

VIDEO AD RENDERED
═════════════════

Archetype: {archetype}
Duration:  {total_seconds}s
Files:
  vertical:  ~/.kai-marketing/renders/{date}/out/vertical.mp4  (1080x1920)
  square:    ~/.kai-marketing/renders/{date}/out/square.mp4    (1080x1080)
  landscape: ~/.kai-marketing/renders/{date}/out/landscape.mp4 (1920x1080)

Platform destinations:
  Meta Reels/Stories: vertical.mp4
  Meta Feed:          square.mp4
  Google/YouTube:     landscape.mp4
  TikTok:             vertical.mp4
  LinkedIn:           landscape.mp4 or square.mp4

Step 6: Offer Variants

"Want to render another archetype? Available: problem-agitation, social-proof, product-demo, lifestyle"

Archetypes

| Archetype | Best For | Duration | Scenes | |-----------|----------|----------|--------| | problem-agitation | Cold audiences, awareness | 10-15s | Hook → Problem → Agitate → CTA | | social-proof | Warm audiences, consideration | 8-12s | Stat → Explain → CTA | | product-demo | Retargeting, feature awareness | 15-20s | Intro → Demo → Benefit → CTA | | lifestyle | Brand building, emotional | 8-12s | Aspiration → Bridge → CTA |

Error Handling

• Node.js not installed: Scaffold only, provide instructions to render elsewhere
• Brand not configured: Direct to kai-config set brand.*
• No ad copy: Direct to /ad-copy or /creative-brief
• Remotion render fails: Show error, suggest checking Node version and dependencies

Chain State

Reads from: ~/.kai-marketing/briefs/, ~/.kai-marketing/config.yaml (brand) Writes to: ~/.kai-marketing/renders/{date}/ Chains from: /creative-brief → /ad-copy → /ad-render
