│   └── WellSaid Labs (actor-compensated voices)
└── Need real-time/interactive?
    └── Cartesia Sonic (40ms TTFA)

Workflow: Voice + Video

1. Write ad script (use ad-creative skill for copy)
2. Generate voiceover with ElevenLabs/OpenAI TTS
3. Generate or render video:
   a. Silent video from Runway/Remotion → layer voice track
   b. Or use Veo/Sora/Seedance with native audio (skip separate VO)
4. Combine with ffmpeg if layering separately:
   ffmpeg -i video.mp4 -i voiceover.mp3 -c:v copy -c:a aac output.mp4
5. Generate variations (different scripts, voices, or languages)

Code-Based Video: Remotion

For templated, data-driven video ads at scale, Remotion is the best option. Unlike AI video generators that produce unique video from prompts, Remotion uses React code to render deterministic, brand-perfect video from templates and data.

Best for: Templated ad variations, personalized video, brand-consistent production Stack: React + TypeScript Pricing: Free for individuals/small teams; commercial license required for 4+ employees Docs: remotion.dev

Why Remotion for Ads

AI Video Generators	Remotion
Unique output each time	Deterministic, pixel-perfect
Prompt-based, less control	Full code control over every frame
Hard to match brand exactly	Exact brand colors, fonts, spacing
One-at-a-time generation	Batch render hundreds from data
No dynamic data insertion	Personalize with names, prices, stats

Ad Creative Use Cases

1. Dynamic product ads Feed a JSON array of products and render a unique video ad for each:

tsx

// Simplified Remotion component for product ads
export const ProductAd: React.FC<{
  productName: string;
  price: string;
  imageUrl: string;
  tagline: string;
}> = ({productName, price, imageUrl, tagline}) => {
  return (
    <AbsoluteFill style={{backgroundColor: '#fff'}}>
      <Img src={imageUrl} style={{width: 400, height: 400}} />
      <h1>{productName}</h1>
      <p>{tagline}</p>
      <div className="price">{price}</div>
      <div className="cta">Shop Now</div>
    </AbsoluteFill>
  );
};

2. A/B test video variations Render the same template with different headlines, CTAs, or color schemes:

tsx

const variations = [
  {headline: "Save 50% Today", cta: "Get the Deal", theme: "urgent"},
  {headline: "Join 10K+ Teams", cta: "Start Free", theme: "social-proof"},
  {headline: "Built for Speed", cta: "Try It Now", theme: "benefit"},
];
// Render all variations programmatically

3. Personalized outreach videos Generate videos addressing prospects by name for cold outreach or sales.

4. Social ad batch production Render the same content across different aspect ratios:

1:1 for feed
9:16 for Stories/Reels
16:9 for YouTube

Remotion Workflow for Ad Creative

1. Design template in React (or use AI to generate the component)
2. Define data schema (products, headlines, CTAs, images)
3. Feed data array into template
4. Batch render all variations
5. Upload to ad platform

Getting Started

bash

# Create a new Remotion project
npx create-video@latest

# Render a single video
npx remotion render src/index.ts MyComposition out/video.mp4

# Batch render from data
npx remotion render src/index.ts MyComposition --props='{"data": [...]}'

Choosing the Right Tool

Decision Tree

Need video ads?
├── Templated, data-driven (same structure, different data)
│   └── Use Remotion
├── Unique creative from prompts (exploratory)
│   ├── Need dialogue/voiceover? → Sora 2, Veo 3.1, Kling 2.6, Seedance 2.0
│   ├── Need consistency across scenes? → Runway Gen-4
│   ├── Need vertical social video? → Veo 3.1 (native 9:16)
│   ├── Need high volume at low cost? → Seedance 2.0
│   └── Need cinematic camera work? → Higgsfield, Kling
└── Both → Use AI gen for hero creative, Remotion for variations

Need image ads?
├── Need text/headlines in image? → Ideogram
├── Need product consistency across variations? → Flux (multi-ref)
├── Need quick iterations on existing images? → Nano Banana Pro
├── Need highest visual quality? → Flux Pro, Midjourney
└── Need high volume at low cost? → Flux Klein, Nano Banana

Cost Comparison for 100 Ad Variations

Approach	Tool	Approximate Cost
100 static images	Nano Banana Pro	~$4-24
100 static images	Flux Dev	~$1-2
100 static images	Ideogram API	~$6
100 × 15-sec videos	Veo 3.1 Fast	~$225
100 × 15-sec videos	Remotion (templated)	~$0 (self-hosted render)
10 hero videos + 90 templated	Veo + Remotion	~$22 + render time

Recommended Workflow for Scaled Ad Production

Generate hero creative with AI (Nano Banana, Flux, Veo) — high-quality, exploratory
Build templates in Remotion based on winning creative patterns
Batch produce variations with Remotion using data (products, headlines, CTAs)
Iterate — use AI tools for new angles, Remotion for scale

This hybrid approach gives you the creative exploration of AI generators and the consistency and scale of code-based rendering.

Platform-Specific Image Specs

When generating images for ads, request the correct dimensions:

Platform	Placement	Aspect Ratio	Recommended Size
Meta Feed	Single image	1:1	1080x1080
Meta Stories/Reels	Vertical	9:16	1080x1920
Meta Carousel	Square	1:1	1080x1080
Google Display	Landscape	1.91:1	1200x628
Google Display	Square	1:1	1200x1200
LinkedIn Feed	Landscape	1.91:1	1200x627
LinkedIn Feed	Square	1:1	1200x1200
TikTok Feed	Vertical	9:16	1080x1920
Twitter/X Feed	Landscape	16:9	1200x675
Twitter/X Card	Landscape	1.91:1	800x418

Include these dimensions in your generation prompts to avoid needing to crop or resize.
