3-Slide Story Ad Set

A campaign brief → a 3-slide vertical Story ad set (3 images + 5s clips each).

Category: social · Difficulty: Advanced · ~Time: 15 min

What you'll make

A complete 9:16 Story / Reels ad sequence: three on-brand slides (hook → value → CTA), each as a still and an animated 5-second clip, sized for Instagram/Facebook Stories, TikTok, and Xiaohongshu. Use this to ship a full launch-ready ad set from a single brief.

Models used

💬 LLM — Claude (expand the brief into a 3-beat story script + per-slide copy)
🎨 Image — Seedream 4.5 (resolve live; e.g. bytedance/seedream-v4.5, sequential: bytedance/seedream-v4.5/sequential) for a consistent 3-slide look
🎬 Video — Seedance 2.5 i2v (resolve live; e.g. bytedance/seedance-2.5/image-to-video)

Steps

Script the 3 beats — "From this brief, write a 3-slide Story ad: slide 1 hook, slide 2 value/proof, slide 3 CTA. Give headline + subline per slide." → atlas_chat with Claude.
Generate 3 consistent stills — "3 matching 9:16 Story slides, same brand palette and layout, texts: [per slide]." → atlas_generate_image with Seedream 4.5 sequential so all three share one style.

Tip: ask the agent to atlas_search_docs for Seedream first to confirm the live 9:16 ratio and how many frames sequential returns.
Animate each slide — "Animate this Story slide: gentle motion + text reveal, 5s, 9:16." → atlas_generate_video with Seedance 2.5 i2v (one call per slide; seedance-2.0-fast for drafts).
Add motion polish — for a stronger CTA slide, see the Photo → Stylized Animated Clip (style-animate) motion recipe.
Assemble — sequence the three 5s clips hook → value → CTA, add captions and a brand end-frame.

Prompt starters

Script (Claude): "Brief: [PASTE]. Write a 3-slide vertical Story ad — slide 1 hook (≤6 words), slide 2 value + one proof point, slide 3 CTA. Headline + subline each, cohesive voice."
Stills (Seedream sequential): "3 matching 9:16 Story slides, modern gradient brand style, bold sans headlines. Slide 1 'STOP SCROLLING', slide 2 'HERE'S WHY', slide 3 'TRY IT FREE'. Mobile-safe margins."
Animation (Seedance 2.5 i2v): "Animate this 9:16 slide: subtle background drift + a clean headline reveal, energetic but smooth, 5 seconds."

Tips & variations

Seedream 4.5 sequential is the key to a unified set — it keeps palette and layout consistent across all three slides; reach for Nano Banana Pro if a slide needs heavier typography.
For dramatic CTA motion, swap Seedance 2.5 i2v for Kling 3 i2v (kwaivgi/kling-v3.0-pro/image-to-video).
Keep every asset true 9:16 (1080×1920) and all key copy inside Story-safe margins so the UI doesn't cover it.
Draft all three animations with Seedance seedance-2.0-fast to lock pacing, then re-render finals at full quality.
