What Veo 3.1 is best at
Native audio generation

First & last frame control
Pin the opening and closing frames and Veo interpolates the motion between them — precise, directable shots.
Photoreal quality ceiling
The reference standard for realistic light, materials, and faces in generated video.
Extend existing videos
Veo 3.1 Extend adds up to 7 seconds to a Veo-generated clip, keeping scene and motion continuous.

The model that made silent AI video obsolete
Before Veo 3, every AI video needed a separate sound pass — stock ambience, foley, or silence. Veo 3.1 generates the audio with the pixels: the wave crash matches the wave, the dialogue matches the lips, the room tone matches the room. For content that ships fast — ads, social, b-roll — removing the audio post step is a bigger deal than any resolution bump.
The family structure makes it practical at volume: full Veo 3.1 for hero shots, Fast and Lite tiers for drafts and high-volume content, and Extend to stretch a great take past its original length. On GenFire all four share one credit balance, so routing each job to the right tier is a dropdown, not a procurement decision.
