​
What is a UGC Avatar Video?

A UGC avatar video features an AI-generated person talking directly to camera about your product. It looks like authentic creator content, but you have full control over the script, avatar, voice, and delivery.

​
How to Create a UGC Avatar Video

1

Open the UGC Avatar Creator

Go to Creative Hub > Video Ads and select the UGC Avatar option. You can also access this from Product to Video.
2

Select Your Product

Choose a product from your catalog or enter details manually. This provides context for the script and visuals.
3

Upload a Product Image

Select or upload a product image to feature in the video alongside the avatar.
4

Choose an Avatar

Browse the avatar gallery and pick an AI actor. Choose someone who matches your target audience and brand personality.
5

Write or Generate the Script

Write the script yourself, or click Generate Script to let AI write one based on your product details. The best scripts are short, conversational, and hook-first.
6

Select a Voice

Pick a voice for your avatar. Preview different voices to find the right tone and energy. Match the voice to the avatar for a natural feel.
7

Adjust Settings

Choose your aspect ratio, tone, and any other creative preferences.
8

Generate and Review

Click Generate. Rendering takes 2–5 minutes. Watch the preview to check the content, pacing, and delivery.
9

Render Final Video (Optional)

The initial result is a preview. For the highest quality output, click Render Final Video to apply pro lip-sync processing — this precisely aligns the avatar’s lip movements to the audio and polishes the final result. Rendering costs additional credits based on video duration. See Render Credit Costs for details.
10

Download or Save

Download the video or save it to your Media Library for use in campaigns.

​
Choosing the Right Avatar

The avatar gallery includes a variety of stock avatars. When selecting:
  • Match your audience — Choose an avatar that your target customer can relate to
  • Consider the tone — Some avatars feel more professional, others more casual
  • Test multiple options — Different avatars can dramatically change ad performance

​
Custom AI Avatars

You can also create a custom AI actor instead of using a stock avatar. Click Create AI Actor and configure:
  • Name — Give your actor a name for easy reference
  • Appearance — Choose gender, age group, and ethnicity
  • Outfit — Select from outfit presets or describe what they should wear
  • Scene — Choose a background setting for the actor
  • Details — Add any additional description to fine-tune the look
AI generates a portrait based on your selections, which you can then use in any UGC avatar video.

​
Script Writing Tips

The script is the most important part of a UGC ad. Here’s what works:
  • Start with a hook — “Stop scrolling if you…” or “I just discovered…”
  • Keep it under 30 seconds — Short and punchy wins on Meta
  • Talk like a human — Write how someone would actually speak, not marketing copy
  • Focus on one benefit — Don’t try to say everything in one ad
  • End with a CTA — Tell viewers what to do next

​
Best Practices

  • Generate 3–5 variations per product with different avatars and scripts
  • Test hooks — The first 3 seconds determine if someone watches
  • Use portrait (9:16) for Stories/Reels and square (1:1) for Feed
  • Pair with image ads — Run UGC videos alongside static images for a diversified creative mix
