Write the motion brief
Describe the subject, camera movement, lighting, and sound cue. A clean brief matters more than a long paragraph when the goal is a short 8-second Veo pass.

Veo 3.1 Fast AI Video Generator
Fast Veo with text, frames, or 1-3 reference images
Use Veo 3.1 Fast when the shot needs Google-style motion without the full quality-tier credit hit. Start from text, animate one or two frames, or guide the clip with up to three reference images, then choose 720p, 1080p, or 4K. It is the Veo page for quick iterations, reference-led material shots, and lower-credit video tests that can still be upgraded when a take works.
- Faster, lower-credit Veo tier
- Reference-to-video with 1-3 images
- Text-to-video and first/last-frame video
- Native audio by default
- 720p, 1080p, or 4K output
Run Veo 3.1 Fast
Write a prompt, add a start frame, or attach up to three reference images, then pick 16:9, 9:16, or Auto and choose 720p, 1080p, or 4K before the run.
Compare Fast With Other Video Models
Stay in the same generator when the shot needs the full Veo quality pass, a longer Seedance take, or a dialogue-first model.
The Veo 3.1 Tier for Fast Reference-Led Iteration
Fast is the Veo option you reach for before the full quality pass: cheaper to test, quicker to compare, and the only current Veo SKU in SupaImagine with reference-to-video.
Veo 3.1 Fast sits between the full Veo 3.1 quality page and the lowest-cost Lite tier. In the current SupaImagine catalog, it keeps the same core Google Veo workflow — text, a start frame, or a first-and-last-frame transition — and adds a material-style reference mode for one to three images. That makes it useful when a product shape, character look, or visual identity needs to survive the motion pass. The tradeoff is clear: use full Veo 3.1 when the final shot deserves the quality tier; use Fast when you need more attempts, a lower credit cost, and a reference-driven path that the full quality SKU does not expose here.

Workflow
Shape a Veo 3.1 Fast Clip From Prompt, Frames, or References
2
Choose the starting material
Use text alone for a new shot, add a start image to animate a still, add a start and end frame for a transition, or attach one to three reference images for the Fast reference mode.
3
Pick aspect and resolution
Select 16:9, 9:16, or Auto, then choose 720p, 1080p, or 4K. Fast starts at 30 credits for 720p, far below the full Veo 3.1 quality tier.
4
Compare and keep the take
The result lands in your private library. Re-run the same material on Fast, send the winning shot to the full Veo page, or compare it with Seedance without losing the prompt.
Fast-specific strengths
Why Veo 3.1 Fast Belongs in the First Pass
The page focuses on the abilities SupaImagine actually exposes: lower-credit Veo runs, reference images, frame animation, native audio by default, and resolution upgrades.
Reference images without a heavy setup
Fast is the Veo 3.1 SKU in SupaImagine that exposes reference-to-video. Add one to three images when the clip needs to remember a product, character, prop, or visual style.
More Veo attempts per credit pool
The 720p Fast run is 30 credits, with 1080p at 45 and 4K at 90. That makes it the practical tier for trying several versions before committing to a full quality pass.
Reference-image direction for quick tests
Use the one-to-three-image reference path when a look, prop, or character needs to guide the clip before you spend credits on a final-quality pass.
Audio starts with the video
Veo 3.1 can generate picture and sound together, so Fast clips can arrive with background audio by default. Sensitive scenes may suppress sound, so this is framed as the default behavior rather than a guarantee.
Vertical and landscape on purpose
Choose 9:16 for social, 16:9 for horizontal edits, or Auto when the input material should guide the shape. Fast is not only a draft button; it still lets you aim the output format.
Upgrade only the version that works
Start with the lighter base render and reserve 1080p or 4K for the shot worth keeping. SupaImagine keeps the run, prompt, and result together in the library.
Fast vs nearby choices
Veo 3.1 Fast, Full Veo, or Seedance — Choose by Material
The right model depends on whether you are testing quickly, finishing a Google-style shot, or directing a longer reference-heavy sequence.

Where Fast fits
Veo 3.1 Fast Use Cases for Reference-Driven Motion
Use Fast when the material is clear and you need several attempts before choosing the keeper.
Reference product passes
Use one to three product references to test how shape, finish, and lighting survive motion before spending more credits on the final quality-tier render.
Character look checks
Use one to three reference images when a face, costume, or silhouette needs to stay recognizable through a short motion pass.
Campaign hook drafts
Draft several hooks, transitions, or vertical cuts with lower Veo credits, then keep the one that sells the campaign idea.
Style continuity shots
Bring a palette, prop language, or art direction into a short video without turning the task into a full multi-clip sequence.
Low-credit insert scouts
Scout quick inserts, scene setters, and cutaway ideas while reserving the heavier quality model for the main campaign shot.
Model comparison passes
Run the same prompt on Fast, full Veo, and Seedance to see whether speed, fidelity, or flexible duration matters most for the shot.
Veo 3.1 Fast Details Before You Run
What is Veo 3.1 Fast?
Veo 3.1 Fast is the lower-credit Fast tier of Google's Veo 3.1 family. On SupaImagine, it can generate video from text, animate one or two frames, or use one to three reference images in the Fast reference-to-video mode.
How is Veo 3.1 Fast different from Veo 3.1?
Fast costs fewer credits and exposes reference-to-video in the current SupaImagine catalog. The full Veo 3.1 page is the quality SKU for a polished short shot; Fast is the speed-and-reference workflow for trying more versions first.
Can Veo 3.1 Fast use reference images?
Yes. The reference mode accepts one to three images. That is different from frame-to-video: frame mode uses a start image or start/end pair, while reference mode uses material images to guide the look of the generated video.
Does Veo 3.1 Fast support 4K?
Yes. SupaImagine exposes 720p, 1080p, and 4K for Veo 3.1 Fast. The current credit table is 30 credits for 720p, 45 for 1080p, and 90 for 4K.
Do Veo 3.1 Fast clips include sound?
Veo 3.1 Fast uses the Veo path where audio is generated by default, so a clip can arrive with sound alongside the picture. Some sensitive scenes may suppress audio upstream, so SupaImagine does not promise sound on every single result.
Are starter credits enough for Veo 3.1 Fast?
No. New SupaImagine accounts receive 10 starter credits, and the lowest Veo 3.1 Fast run currently starts at 30 credits. Use the pricing page or a paid credit pack when you are ready to render video.
Can I use Veo 3.1 Fast videos commercially?
Commercial-use rights are tied to paid SupaImagine plans under the site's terms. Starter-credit output is for evaluating the workspace, while paid-plan videos are the path for client, ad, and commercial work.
