Veo 3.1 Fast
Google's fast variant. Draft clips at a fraction of the cost.
The speed-optimised version of Veo 3.1, built for exploration and iteration rather than final deliverables. Generates roughly twice as fast at up to 80% lower cost, with the same native audio pipeline. Quality is good but not quite Standard: fine detail and complex textures show the difference on close inspection. Use Fast to find the right direction, then promote to Standard for the final render.
Example outputs
“A claymation robot character waves at the camera then turns and waddles off set, soft studio lighting, playful Aardman-style stop-motion animation”
“A concept car rotating slowly on a dark turntable, matte grey paint catching dramatic studio spotlights, smooth 360-degree orbit, automotive reveal”
“A pair of premium headphones descending into frame against a vibrant pink-to-purple gradient, slow rotation revealing every angle, product commercial”
“A slow forward dolly through a Zaha Hadid style museum atrium, sweeping white curved walls flowing overhead, skylights casting shifting light across polished floors”
“A 3D game character samurai cat unsheathes a sword on a rooftop at sunset, camera orbiting as wind catches the armour details, cinematic game trailer”
“A smartphone on a studio stand displaying a fitness app, camera pushing in slowly as the UI animates through dashboard stats, commercial product ad lighting”

Veo 3.1 Fast generates video at roughly twice the speed of Standard. The visual quality difference is minimal. For most concept work, iteration passes, and internal reviews, the difference is invisible. For final client deliverables, switch to Standard.
The cost difference is significant. At up to 80% cheaper per clip, Fast makes volume work practical. Generate 5 variations of a walkthrough angle instead of committing to one. Test 3 different camera movements for a product reveal. Explore mood and pacing before locking a direction. This is the model for the exploration phase of video production.
The two-stage workflow is where Fast and Standard work best together. Use Fast for rapid exploration: test prompts, angles, durations, and compositions at low cost. Once you have the direction locked, regenerate the final version with Standard for maximum quality. This mirrors how design professionals already work: rough drafts first, polished deliverable last.
Quick previews, fast decisions
At just over a minute per clip, Veo 3.1 Fast lets you preview ideas before committing to a full-quality render. Test a walkthrough angle, check a camera path, verify a product rotation. Make decisions based on generated previews, not imagination.
Same audio, less cost
Fast retains the same native audio pipeline as Standard. Dialogue, sound effects, ambient audio, and music are generated in a single pass. The audio quality is identical to Standard. Only the visual fidelity shows a marginal difference, and only in fine detail under close inspection.
The two-stage video workflow
Draft with Fast, deliver with Standard. This is the most cost-effective way to produce video on Stensyl. Explore 5-10 variations with Fast, then render the final version with Standard. Total cost is lower than generating 3 Standard clips to find the right one.
