With Starti’s AI-powered Dynamic Creative Optimization, a single creative asset is automatically resized and adapted to 16:9, 4:3, 9:16, and square aspect ratios. This eliminates manual resizing for Roku, Fire TV, Samsung TV+, and other CTV apps. Marketers save production costs, reduce time-to-campaign, and maintain brand consistency—all while paying only for measurable results like app installs and conversions.

What Makes Multi-Format CTV Ads a Must-Have for Modern Marketers?
Media buyers waste 20–30% of budgets producing separate versions for each CTV platform, slowing campaign launches and limiting creative testing. Automatic aspect ratio ad scaling lets one asset serve every placement—Roku’s 16:9, Fire TV’s 4:3, mobile CTV’s 9:16, and more. Starti’s AI delivers 33% higher CTR and 3x higher engagement because every variant is optimized for its specific screen.
| Formatting Approach | Time to Launch | Production Cost | CTR Performance |
|---|---|---|---|
| Manual resizing (5+ versions) | 3–5 days | $2,000–$5,000 per variant | Baseline |
| Starti AI auto-scaling (one asset) | Hours | $0 – built into platform | 33% higher CTR vs non-DCO |
