The short answer

Veo 3.1 is an AI video model that turns a text prompt or a still image into a short cinematic clip with synchronized native audio. It is prized for physical realism, steady camera motion, and close prompt adherence. In FXI Studio you direct it one shot at a time and chain shots into a continuous scene.

What Veo 3.1 is best for

Veo 3.1 is a text-to-video and image-to-video model that generates a short clip with sound baked in. Its strengths are physical plausibility, believable camera movement, and staying close to what the prompt actually asked for, which is what makes it a good default for establishing shots and dialogue moments.

It is the model to reach for when a shot has to read as filmed rather than assembled: a slow dolly across a room, a character speaking a line, a wide that has to hold its own light.

A sweeping cinematic establishing shot of a coastal cliff at dusk, volumetric light — Native audio means the sound arrives with the frame, not bolted on after.

How FXI Studio directs Veo 3.1

In FXI Studio you do not drop a prompt and hope. You pick Veo 3.1 for a shot, see its clip length and credit cost before you commit, and describe the coverage you want. Bezaleel, the AI film director, proposes the camera move and names the lens so the shot matches the one you already see.

Reference binding on Veo 3.1 applies at 16:9 and 8 seconds, so when you attach a still to steer the look, the studio shows you that constraint in place rather than letting a silent mismatch waste a render.

Chaining Veo shots into a scene

One clip is a moment; a scene is a run of shots that belong together. FXI Studio uses frame chaining so the last frame of one Veo shot seeds the first frame of the next, keeping light, motion, and character continuous across the cut.

That is the difference between a single generated clip and a directed sequence: each shot answers to the one before it instead of starting from scratch.

Step by step

How to use Veo 3.1 in FXI Studio

1
Open the studio
Go to the studio and start a new shot. Veo 3.1 appears in the model picker with its clip length and credit cost shown up front.
2
Describe the shot
Write what happens in the shot. Bezaleel proposes the camera move and names the lens so the coverage matches your vision.
3
Attach a reference if needed
To steer the look, attach a still. On Veo 3.1 references bind at 16:9 and 8 seconds, and the studio shows that constraint before you generate.
4
Generate and review
Render the shot, then review it with its native audio. Revise the lens, framing, or motion and re-run until it lands.
5
Chain into the next shot
Use frame chaining so the last frame of this Veo shot starts the next one, keeping the scene continuous.

Frequently asked questions

What is the Veo 3.1 AI video model?

Veo 3.1 is an AI video model that generates a short cinematic clip with synchronized native audio from a text prompt or a still image. It is known for physical realism, steady camera motion, and close prompt adherence.

Does Veo 3.1 generate sound?

Yes. Veo 3.1 generates synchronized audio with the frame rather than requiring a separate pass, which is why it suits dialogue and establishing shots where sound and picture have to match.

Can Veo 3.1 use an image as a reference?

Yes. Veo 3.1 accepts a still to steer the look and motion. In FXI Studio reference binding applies at 16:9 and 8 seconds, and the studio surfaces that constraint before you commit a render.

How do I make more than one Veo shot flow together?

Use frame chaining. In FXI Studio the last frame of one Veo shot seeds the first frame of the next, so light, motion, and character stay continuous across shots instead of resetting each clip.

Is Veo 3.1 free to try?

FXI Studio is in Open Beta with 65 free credits on signup and no credit card required, which is enough to direct several short video shots and see how Veo 3.1 renders your coverage.
