Make a UGC Ad With Veo 3.1 Inside Claude

Generate a Veo 3.1 Quality or Fast UGC ad by chatting with Claude once Polaris is connected as an MCP tool.

GuideJul 15, 2026·2 min read

To make a UGC ad with Veo 3.1, connect Polaris to Claude, describe the ad in chat with a product photo or script attached, and choose Veo 3.1 Quality or Fast from the tappable option cards. The finished ad renders live in the conversation.

Step-by-step

  1. Make sure Polaris is connected. The MCP connector at polarisugc.com/api/mcp should already be authorized in your Claude settings.
  2. Describe the ad in plain language. Attach a product photo or paste a script and tell Claude what kind of UGC ad you want.
  3. Pick Veo 3.1 on the model card. Claude will present video model options as tappable cards; choose Quality for more polish or Fast for quicker turnaround.
  4. Fill in the remaining settings. Aspect ratio, duration, voiceover, and captions all come through the same card-based flow.
  5. Watch it render. The Polaris panel shows live progress directly in the chat, typically finishing within a couple of minutes.
  6. Iterate if needed. Use Recreate to try the same brief with a different product, or request a parallel batch to test a few hooks at once, downloadable together as a ZIP.

Pro tips

  • If you're unsure between Quality and Fast, generate one of each for the same brief in a single batch and compare them directly rather than guessing which suits your ad.
  • Add an ElevenLabs voiceover and Suno-generated background music in the same request instead of sourcing audio elsewhere.
  • Run your script through Copy Judge before generating, catching a weak line before the render is cheaper than after.

Honest caveats

Veo 3.1 ads in Polaris are built around your own product photo or script, there is no stock-avatar library to browse. The AI actor performs your script, it doesn't clone a named real person. Treat any render as a first draft to test, not a guaranteed winner. And if your niche is regulated, such as supplements or finance, keep an eye on the script yourself so claims stay compliant, avoiding disease/cure or guaranteed-result language.

Frequently asked questions

What's the difference between Veo 3.1 Quality and Fast?
Both are model options Claude will present as tappable cards; Quality favors polish, Fast favors turnaround, but neither is a default you have to guess at, Claude asks.
Can I use Veo 3.1 without the web app?
Yes. The web app is a secondary surface. Chatting with Claude after the connector is authorized is the primary workflow.
How do I add captions to a Veo 3.1 ad?
Burned-in captions are a one-click option after the render, no separate editing tool needed.
What if I pick the wrong settings by mistake?
You can just ask Claude to regenerate with different option-card choices, or use Recreate on a version you liked as a starting point.
