Question 1

What can I make with Veo 3.1 Fast?

Accepted Answer

Storyboards, ad iterations, social content, music video drafts, character animation, talking-character scenes, and any clip you want to iterate on quickly without spending a lot per try. Animate a still image into a full scene. Pin the opening and closing frames. Generate dialogue and ambient sound alongside the picture. Strong with realistic physics, lighting, and camera movement.

Question 2

Does Veo 3.1 Fast generate audio and dialogue?

Accepted Answer

Yes. Veo 3.1 Fast generates audio natively. Toggle audio in the composer and the model produces synced dialogue, ambient sound, and effects in the same pass as the picture. The result lands as a single video file with sound baked in, so you can drop it straight into an edit.

Question 3

Can I animate an existing image with Veo 3.1 Fast?

Accepted Answer

Yes. Upload a starting image and describe what should happen. Veo 3.1 Fast turns the still into a moving scene with consistent subject, lighting, and composition. You can also pin a last-frame image and let the model interpolate the motion between the two.

Question 4

What is the difference between Veo 3.1 Fast and Veo 3.1?

Accepted Answer

Veo 3.1 Fast is the speed tier. It renders quickly, costs less per second, and skips reference images. Veo 3.1 is the full-fidelity tier from the same model family. It produces the cleanest motion and detail and supports up to three reference images for character consistency. Use Fast for storyboards, ad iterations, and high-volume work. Use the full Veo 3.1 for hero shots and final delivery. Both share the same prompt and input interface in Visual Sandbox, so you can switch between them on the same project.

Question 5

What aspect ratios and resolutions does Veo 3.1 Fast support?

Accepted Answer

Landscape 16:9 and portrait 9:16, at 720p or 1080p. 16:9 fits landing pages, trailers, and YouTube. 9:16 fits TikTok, Reels, and Shorts.

Question 6

How long can a Veo 3.1 Fast video be?

Accepted Answer

Four, six, or eight seconds in a single generation. For longer pieces, chain multiple clips in Visual Sandbox by feeding the last frame of one clip in as the first frame of the next.

Question 7

How do I write prompts that work well with Veo 3.1 Fast?

Accepted Answer

Be specific about the subject, the camera, the lighting, and the motion. Describe what is in the frame, then how the camera moves, then how the subject moves. For dialogue, write the line you want spoken in quotes inside the prompt. A locked camera with a moving subject usually reads cleaner than moving both at once. Short prompts work for simple ideas. For cinematic shots and ad creative, longer prompts with structured detail produce more consistent results.

Question 8

How much does a Veo 3.1 Fast video cost?

Accepted Answer

Veo 3.1 Fast is billed per output second. With audio on, the rate is $0.15 per second. With audio off, it is $0.10 per second. Visual Sandbox shows the exact cost before you generate, and charges per clip when the result is delivered. There is no subscription, no monthly minimum, no top-up.

Question 9

Can I use Veo 3.1 Fast videos commercially?

Accepted Answer

Yes. Google's Veo 3.1 terms allow commercial use of generated videos. You are responsible for the prompt and the final use, especially when the output includes likenesses, logos, or copyrighted material.
