Google Veo 3.1

Veo 3.1 generates video and sound together, so dialogue, ambient noise and effects land in the same take as the picture. A rain-soaked street scene arrives with the thunder timed to the lightning instead of a silent plate you dub later. For anyone used to adding audio in post, that removes a whole pass. The catch is that you can't pick a specific voice, so a brand that needs one consistent narrator still records it separately.

A single Veo 3.1 generation lasts 8 seconds, and scene extension carries the action forward from the last moment of the previous clip, which is the closest this AI video generator gets to a running shot. Each pass adds about 7 seconds, and you can stack the passes to build a clip that runs for minutes. It keeps the environment sound going as it extends, so the audio doesn't cut when the visual continues. The trade-off is that long extensions can drift, which means the more passes you chain, the more you'll want to check continuity.

You can hand Veo 3.1 a starting image and an ending image and let it fill the motion between them. This turns a jump between two shots into a single flowing move, which is handy when you want a transition that reads as one camera gesture. It also gives animators a way to land on an exact pose. The output is only as good as the two frames you provide, so a weak endpoint shows up in the middle.

Veo 3.1 can take up to three reference images to steer a shot, covering things like a character, an outfit and a setting. This differs from image-to-video, which uses one image as the opening frame. Here the images inform the look and the content while the model keeps the subject consistent across a set. The constraint is the format: reference-led generation is tuned for 8 second 16:9 clips, so it won't fit every aspect ratio.

Two editing tools let you change a scene after the fact. Insert adds an element, whether a believable detail or a creature that shouldn't be there, and the model adjusts lighting and shadows so the addition sits in the shot. Remove erases an object or a person and rebuilds the background behind it. Both cut the need to reshoot for small changes, but the availability of each tool depends on the surface and the rollout stage.

Veo 3.1 ships as Standard, Fast and Lite, which lets you match cost to the job. Veo 3.1 pricing splits by the job you're doing. Standard gives the best quality at $0.40 per second for 720p and 1080p and $0.60 for 4K. Fast trades some fidelity for $0.10 to $0.30 per second, and Lite targets high volume at $0.05 to $0.08 per second without 4K. Pick Standard for a hero shot, Lite for a feed of test runs, and Fast when you want a middle ground.
