Why use Veo 3.1 for video?
Higher fidelity rendering with improved lighting and material accuracy
Veo 3.1 produces cleaner surfaces, stronger shading, and more realistic material responses than Veo 3. This makes it ideal for premium UA ads, polished trailers, and cinematic promotional content.
Enhanced physics and interaction logic for more believable scenes
Motion, object interaction, and environmental reactions feel more grounded. Veo 3.1 is strong for action moments, character performances, and narrative beats where realism and physical cohesion matter.
Stronger long sequence stability and character consistency
Characters maintain identity and proportions more reliably across extended clips. This allows teams to create multi shot promos, event intros, or longer LiveOps trailers without drifting detail or model collapse.

Premium UA video hooks with improved clarity and impact
Generate cinematic 1 to 3 second sequences with expressive action, clean silhouettes, and high readability. Veo 3.1’s improved fidelity makes UA creatives feel more polished and high production value.

Character driven trailers and cosmetic showcase videos
Create expressive character performances with smoother motion, sharper detail, and richer lighting. Perfect for seasonal skins, hero intros, and shop or LiveOps promotional assets.

Narrative and worldbuilding trailers for event launches
Produce multi shot sequences that highlight biomes, environments, and event themes with strong coherence. Veo 3.1 brings more atmospheric depth and detail to LiveOps trailers and thematic storytelling.
FAQ
How much does Veo 3.1 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.
