Fast High-Quality AI Video with Google Veo 3.1 Fast
Google Veo 3.1 Fast generates high-quality videos from text or images at a fraction of the cost of standard Veo 3.1. Supports text-to-video, image-to-video, and first-last-frame mode with native audio at up to 4K resolution.
What makes Veo 3.1 Fast different
The full Veo 3.1 feature set, at a lower rate
Fast is not a stripped-down model: it keeps text-to-video, image-to-video, first-last-frame control, native audio, and resolutions up to 4K. What changes is the price — $0.15 per second with audio at 720p/1080p versus $0.40 on standard Veo 3.1, so a 5-second sound-on clip costs $0.75 instead of $2.00.
Built for iteration
Prompting AI video is an iterative craft — most shots take several attempts. At Fast's rates you can afford those attempts: explore variations, camera moves, and prompt phrasings cheaply, then re-run the winning prompt on standard Veo 3.1 or at 4K for the final render. On a Scenetra board that's just two nodes sharing one prompt.
Native audio with a real discount switch
Like its bigger sibling, Fast generates synchronized dialogue, ambience, and effects. Audio is a toggle: at 720p/1080p you pay $0.10 per second with it off and $0.15 with it on, so silent b-roll and drafts cost even less.
4K when you need it
Fast can render full 4K at $0.30-$0.35 per second — cheaper than standard Veo 3.1's HD rate with audio. For delivery formats where resolution matters more than squeezing out the last bit of fidelity, Fast 4K is the value pick of the Veo family.

What is the difference between Veo 3.1 and Veo 3.1 Fast?+
Same family, different speed-cost point. Fast is tuned for quicker, cheaper generation: $0.15 per second with audio at 720p/1080p versus $0.40 on standard Veo 3.1. Standard Veo 3.1 remains the pick for maximum fidelity on final renders; Fast covers iteration, drafts, and volume work. Both support text-to-video, image-to-video, first-last-frame, native audio, and up to 4K.
How much does Veo 3.1 Fast cost?+
On Scenetra: $0.10 per second without audio or $0.15 with audio at 720p/1080p, and $0.30-$0.35 per second at 4K. A 5-second HD clip with audio costs about $0.75; 10 seconds about $1.50. Billing is per generation from your credit balance.
Is Veo 3.1 Fast good, or noticeably worse than standard Veo?+
It's genuinely good — same model family, same prompt understanding, native audio included. On complex scenes fine detail and motion can be a notch below standard Veo 3.1, which is why many creators draft on Fast and re-render keepers on standard. For social-length content, many find Fast output is final-quality as-is.
Does Veo 3.1 Fast support audio and 4K?+
Yes to both. Native synchronized audio is on by default (toggle it off to drop from $0.15/s to $0.10/s at HD), and resolution goes up to full 4K at $0.30/s without audio or $0.35/s with.
How can I try Veo 3.1 Fast for free?+
New Scenetra accounts start with free welcome credits and a 7-day trial — at Fast's rates that covers a good number of clips. After the credits, it's pay-per-generation with no subscription gate. Scenetra runs in the browser, so there's nothing to install.
When should I use Veo 3.1 Fast vs Veo 3.1 Lite?+
Fast when you still want headroom — 4K, and quality close to standard Veo. Lite when cost per clip matters most: it starts at $0.03 per second but tops out at 1080p. A common split is Lite for high-volume social output and Fast for anything a client will see.
