Create amazing video content with AI Avatar on Layer
The complete content creation platform for modern game teams. From concepting to polished in-game assets - across Image, 3D, Video, and Audio.
Why use AI Avatar for video?
Natural lip sync and facial motion from a single image
AI Avatar animates realistic mouth shapes, eye movement, and subtle expressions directly from a static portrait. It is ideal for creating talking characters, spokesperson style videos, and in game announcements without recording live footage.
Script driven performance for consistent character delivery
The model responds directly to text input, producing clear, controlled speech animations based on any provided script. This makes AI Avatar perfect for tutorials, onboarding flows, narrative dialogue, or LiveOps communication.
Stable identity retention with smooth expression transitions
AI Avatar maintains face shape, style, and proportions across the entire clip. Expression changes, head turns, and micro motions stay coherent, making the output clean enough for marketing, social content, and in app messaging.
Talking character videos for UA creatives and social ads
Turn character portraits into short dialogue driven clips that explain mechanics, highlight features, or introduce new content. AI Avatar helps teams create voice forward ads without filming talent.

In game tutorials, onboarding steps, and narrative delivery
Produce guided explanations or character driven dialogue sequences that improve player understanding. AI Avatar works well for NPC narrators, quest intros, and player onboarding flows.
LiveOps announcements, seasonal updates, and shop messages
Create quick promotional videos where a character introduces new skins, events, or limited time offers. AI Avatar supports fast, script based iteration for frequent LiveOps content cycles.
FAQ
How much does AI Avatar cost? Is it free?+
How does Layer's pricing work?+
There are no seat fees, feature gates, or plans on Layer. Instead, our platform uses a consumption based system with Creative Units (CUs) with a flexible monthly subscription. Every generation on Layer (image, video, 3D, or audio) consumes a Creative Unit, and you only pay for what you create.
