Plain-English overview

What Veo 3.1 actually is

Veo 3.1 handles short clips with synchronized audio and supports generation, extension, interpolation, and reference-driven workflows through variant-specific endpoints. Resolution, duration, and input mode are linked; not every combination is available.

Google publishes an unusually useful request-latency range of 11 seconds to six minutes during peak periods. That is an operational range, not a quality benchmark, and higher resolution can increase latency and price.

Good fit for

Short cinematic clips with native audio
4K experiments and video extension
