Veo 3.1 Fast vs Infinity Star
Veo 3.1 Fast edges out Infinity Star overall (Veo 3.1 Fast 52.0 vs Infinity Star 25.0.) As of February 2026, Veo 3.1 Fast is a solid daily driver. It's cheap, fast, and produces about 80% of the quality of Veo 3.1. It really struggles with all the animation categories and suffers from the same glossy, below-average cinematography issues that have plagued the Veo 3 class of models. Image-to-video tasks also struggle more than prior models. One of the few models that produces racially diverse output without defaulting to a specific look. The main tradeoffs are in Animation categories, Cinematography, Has a glossy aesthetic, Closed-source, requires paid subscription, Image-to-video tasks, where Infinity Star tends to score better.

Inside an opulent royal greenhouse filled with orchids, a blue ceramic watering can sits in the foreground on the left, and a terracotta pot with a single red tulip sits in the foreground on the right. A shallow reflecting pond runs through the middle and must show clear reflections. At second 2, a hummingbird enters from the top center and hovers directly above the tulip for exactly three seconds, then exits upward at second 5. The watering can and pot must remain fixed.

Inside a gilded palace ballroom with tall mirrors and a marble floor, a gold crown sits on a red velvet cushion on a small round table in the foreground. A silver candlestick stands exactly to the right of the cushion. In the background, a crystal chandelier hangs centered above the room. At second 2 the chandelier sways gently left-to-right for exactly three seconds; at second 6 a gloved hand enters from the left and extinguishes only the rightmost candle on the candlestick. The crown and cushion must never move.”

Single continuous shot in a sci-fi hangar with glossy floors and strong backlight haze. Keep a parked spaceship on the left, a glowing door panel on the right wall, and a metal crate centered in the foreground. A female lead runs from the background toward the crate and pivots around it without touching it. A small drone swoops in from the right and scans her with a sweeping light beam as it passes overhead. She slides behind the crate for cover, then pops out and slaps the glowing door panel once. The door panel flashes brighter and she holds in a ready stance facing it. The crate must never move and the spaceship must remain stationary. No cuts.
