What is an AI video ad generator?

An AI video ad generator is a tool that turns a short idea into a launch-ready video ad — script, scenes, voice and format included — without an editing timeline or prompt engineering.

  • Describe the concept, pick an AI model, and set the format and length
  • Review the script, approve the scenes and click continue until the video is rendered
  • Outputs in 1:1, 4:5 and 9:16 are framed for their placement rather than cropped
  • The result lands in the creative library that AI Campaign Builder uses
How it works

AI video ad generator: 6 steps from prompt to render

Pick A Model

Choose from top AI video models — Sora 2, Veo 3.1, Hailuo AI and Seedance Lite.

  • Each shows its render speed and credit cost
  • The builder suggests a good default for your brief in one click
  • Explore on a fast model and ship on a slower one

  • Choosing the placement first means the subject is framed for its destination

Hit Create and your video renders while you wait — you can even leave the screen and come back.

FAQ

Common questions

Just an idea in plain words. Type a short description of the scene and motion, and the built-in Enhance feature expands it into a full prompt with the right look and camera move, so no prompt-writing skill is required. A start frame is optional, but adding one gives the model a fixed subject to work from.

You can pick from top AI video models, including Sora 2, Veo 3.1, Hailuo AI and Seedance Lite. Each model shows its render speed and credit cost, and the builder suggests a good default for your brief that you can override anytime. Switching models keeps your prompt, so the same brief can run through a second engine.

The common ad formats: 9:16 for stories and reels, 1:1 for feed, and 16:9 for landscape placements. You choose the ratio, resolution and clip length — typically 5s or 10s — before generating so the output fits the placement, which is what keeps the subject inside the safe area.

One clip per generation. When you want alternates, rerun the same prompt — optionally tweaking the wording, model or duration — to explore different angles and motion, then keep the strongest. Changing one thing per rerun shows which variable actually moved the result.

Upscale it, rerun it with a tweak, download it in full resolution, or create an ad set directly from the result to launch it as a campaign. The handoff carries the finished clip into the campaign step, with no export-and-reupload round trip.

Platform access is free, managed spend carries a 1% fee with no subscription, and AI generation is billed in tokens rather than a fixed plan.

Teams that start from a product URL instead of an idea use the companion AI Video Builder, and finished scenes can be fine-tuned in the AI Video Editor. Generation is billed in tokens on top of 1% of ad spend, with no subscription.

Describe an idea, pick an AI model, set the format and length, and generate launch-ready video ads — no editing timeline, no prompt engineering. Starting from a product URL instead of an idea? AI Video Builder assembles the whole ad from the link. No editing timeline, no prompt engineering, no stock hunting. Each step feeds the next — you just review and click continue.
