How to Create Video Ads with Seedance
A complete workflow for creating professional video advertisements using Seedance AI — from prompt structure to platform-ready output. No filming, no studio, no video team required.
Why AI-generated video ads are replacing studio production for many businesses
A professional product video ad used to cost $1,000–$10,000 to produce. Studio, photographer, video editor, post-production. For small and mid-size businesses, that budget was out of reach — and the turnaround was measured in weeks.
AI video generation changes this equation. With a structured prompt, Seedance can produce a commercially usable product video ad in under 60 seconds — without a camera, studio, or crew. The output quality, for product demo and lifestyle-style ads, is increasingly competitive with mid-range production budgets.
This guide covers the exact workflow: how to write Seedance prompts for ads, which platform specs to use, what types of ads work best, and 8 ready-to-copy ad prompt templates across different formats and platforms.
4 Ad Types You Can Make with Seedance
Each type has a different prompt structure and visual priority.
Visual hook: Product as the immediate visual subject — revealed in the first frame
Ratio / Duration: 16:9 or 1:1 · 8 seconds
Orbit the product, use rim lighting for premium feel, close on a detail reveal.
Visual hook: Person or scene fills the vertical frame — product appears mid-clip
Ratio / Duration: 9:16 · 5–7 seconds
Handheld or UGC-style, authentic feel. Product name or pack shot appears naturally.
Visual hook: Aspirational scene — product subtly integrated into the environment
Ratio / Duration: 16:9 · 8–15 seconds
Cinematic quality, strong color grade, scene tells a brand story.
Visual hook: Product with urgency visual cues (multiple products, laydown, energy)
Ratio / Duration: 9:16 or 1:1 · 5 seconds
Fast camera move, bold visual contrast, high energy. Add text overlay for offer.
5-Step Ad Creation Workflow
Follow these steps in order. Skipping step 2 (platform specs) before writing the prompt is the most common mistake — the ratio and duration must shape the entire prompt structure.
Define your ad goal and format
Three ad goals drive different prompt structures. Conversion ads (direct sales, product pages) need a clear product reveal as the visual hook — the product must be legible in the first 2 seconds. Awareness ads (brand, lifestyle) lead with scene and emotion. Engagement ads (social, challenges) need authentic, low-production-value aesthetics. Pick your goal first — it determines which elements your prompt front-loads.
Choose your platform and lock specs
Platform specs are not optional — they go at the end of every Seedance ad prompt. Write them before you write the rest of the prompt so you don't forget. TikTok: 9:16, 5 seconds. Instagram Reels: 9:16, 7 seconds. Instagram Feed: 1:1, 8 seconds. YouTube Pre-roll: 16:9, 6–15 seconds. Facebook Feed: 16:9 or 1:1, 8–15 seconds.
Build your ad prompt using the formula
Ad prompts follow a tighter formula than general video prompts: Subject + Product Detail → Camera → Scene/Lighting → Ad Style → Platform Specs. For product ads, the subject description is the most important element — material, finish, color, and shape. For social ads, the scene sets context and mood. The "ad style" anchor (e.g. "premium e-commerce advertisement," "authentic UGC-style") tells the model the commercial register to aim for.
Generate, review, iterate
First generation rarely needs to be perfect — generate, review for product legibility and visual quality, then adjust one element at a time. If the product is not prominent enough, increase material specificity. If the lighting feels flat, add a rim light or backlight to the prompt. If the camera move is wrong, replace it with a named technique from the camera reference. Iterate in small steps, not by rewriting the whole prompt.
Add text overlays and deploy
AI-generated video clips are the visual asset — your hook text, CTA, and offer copy are added in a video editing tool or directly in the ad platform's creative editor (TikTok Ads Manager, Meta Ads Manager). Keep your generated clip as clean and product-focused as possible; the text layer handles the conversion message. Export at the highest available quality before uploading.
Platform Specs Reference
Always write the ratio and duration into your Seedance prompt before generating. Use these as the closing line: e.g. “— 5 seconds, 9:16”
| Platform | Ratio | Duration | Notes |
|---|---|---|---|
| TikTok | 9:16 | 5–9s | Fill the full screen. Fast hook. Authentic or UGC-style performs best. |
| Instagram Reels | 9:16 | 7–15s | Similar to TikTok. Higher tolerance for polished visual quality. |
| Instagram Feed | 1:1 or 4:5 | 3–60s | Square or portrait. Product ads at 8s perform well. |
| YouTube Pre-roll | 16:9 | 6–15s | Skip-proof hook in first 5s. Premium visual quality rewarded. |
| Facebook Feed | 16:9 or 1:1 | 5–30s | Sound-off optimised. Product and offer must be legible visually. |
| Twitter / X | 16:9 or 1:1 | 5–30s | Landscape preferred. Brand and product should be clear in first 3s. |

Frequently Asked Questions
Can Seedance generate video ads without real footage?
Yes. Seedance generates video from a text prompt or reference image alone — no filming, studio, or actors required. For product ads, describe the product material, surface, camera movement, and lighting. For lifestyle or brand ads, describe the scene, subject behaviour, and atmosphere. The output is a downloadable video clip ready for editing and deployment.
What is the best aspect ratio and duration for a TikTok ad in Seedance?
9:16 vertical at 5 seconds is the most effective combination for TikTok ads generated with Seedance. TikTok's algorithm favours content that fills the full vertical screen. Keep the ad to 5 seconds to optimise for completion rate — shorter ads complete more often and are rewarded by the algorithm. State "— 5 seconds, 9:16" at the end of your Seedance prompt.
How is an ad prompt different from a general video prompt?
Ad prompts prioritise product legibility and commercial aesthetic over cinematic storytelling. For product ads: name the product material and finish explicitly, use clean backgrounds (not complex environments), and select camera moves that reveal the product clearly (orbit, close-up push-in). For social ads: optimise for the vertical format and fast visual hook. Always close with the platform-specific duration and ratio.
