Veo 3.1 Fast: Text & Image to Video Online
Bottom line
Veo 3.1 Fast: one flat-rate clip per generation for 40 credits, no duration selector, 16:9 or 9:16. Start from a prompt or a still image in the Text to Video tool; VdoBloom shows the exact credit cost before each Veo 3.1 Fast run, with no separate Veo 3.1 account.
Veo 3.1 Fast is Google's quicker-tier video model on VdoBloom. Unlike Kling or Runway, there's no duration selector at all — every generation produces one fixed-length clip, billed at a flat 40 credits regardless of what you generate. Aspect ratio is limited to 16:9 or 9:16; the 1:1 square option available on most other VdoBloom video models isn't offered for Veo.
Veo 3.1 Fast supports three input modes through VdoBloom's Veo3Controls panel: Text to Video (no images), Frame Transition (upload a first and a last frame, 2 images), and Reference Mode (3 reference images, 16:9 aspect ratio only, and available on Fast only — Veo 3.1 High Quality doesn't support it). An Auto-Translate toggle converts non-English prompts before generation.
VdoBloom lists this model simply as 'Veo 3.1' internally, so there's no separate 'Veo 3' or 'Veo 3.1 Lite' listing to choose between — Fast and High Quality are the only two tiers available. Prompts can run up to the platform default of 5,000 characters, well above Kling's 2,500 or Runway's 1,800 limits.
What it costs on VdoBloom
Veo 3.1 Fast is a flat 40 credits per generation — there's no duration or resolution control to change that price, since Veo 3.1 has no duration parameter on VdoBloom at all. The cost is shown before you generate and refunded automatically if the generation fails.
Veo 3.1 Fast vs Veo 3.1 High Quality
Fast costs 40 credits per generation; High Quality costs 160 credits — four times more. Both share the same input modes and 16:9/9:16 aspect-ratio limit, with one exception: Reference Mode (3 images, 16:9-locked) is available on Fast only. High Quality drops that mode but is priced for higher rendering quality.
Use Fast for iteration, reference-image generation, or when 40 credits fits the budget better. Use High Quality when the extra 120 credits is worth it for the final render and you don't need Reference Mode.
Input modes and limits
Veo 3.1 Fast supports three generation modes: Text to Video (no images), Frame Transition (a first and a last frame, 2 images), and Reference Mode (3 images, 16:9 only, Fast tier only). An Auto-Translate toggle converts non-English prompts to English before generation. Prompts can run up to 5,000 characters, and aspect ratio is limited to 16:9 or 9:16 — there's no 1:1 option and no duration selector.
What creators use Veo 3.1 Fast for
- Fast-turnaround text-to-video generation where the 40-credit flat rate matters more than resolution control.
- Frame-transition clips where you supply a first and last frame and let Veo fill in the motion between them.
- Reference-mode generation using 3 images to guide a 16:9 output — a mode only available on the Fast tier.

Frequently asked questions
How much does Veo 3.1 Fast cost on VdoBloom?
A flat 40 credits per generation, regardless of which input mode (text, frame transition, or reference) you use.
Is Veo 3.1 Fast free?
New accounts start with 10 free credits — a quarter of the 40 credits a single Veo 3.1 Fast generation costs, so a top-up is needed to run one.
How long can a Veo 3.1 Fast video be?
VdoBloom doesn't expose a duration selector for Veo 3.1 — the duration is fixed by the model. Every generation produces one fixed-length clip at the flat 40-credit price.
What is Veo 3.1 Lite? Does VdoBloom have it?
VdoBloom doesn't list a separate 'Veo 3.1 Lite' model — the two Veo 3.1 tiers available are Fast and High Quality.
How do I use Veo 3.1 for free unlimited generation?
There's no free-unlimited option on VdoBloom — every generation after the 10 free signup credits draws from a paid credit balance, and the exact cost (40 credits for Fast) is shown before you generate.
What aspect ratios does Veo 3.1 Fast support?
16:9 or 9:16 only — the 1:1 square ratio available on most other VdoBloom video models isn't offered here.
How do I use Veo 3.1 Reference Mode?
Upload 3 reference images with the aspect ratio locked to 16:9 — Reference Mode only works on the Fast tier, not on Veo 3.1 High Quality.
Is Veo 3.1 censored / does it allow NSFW content?
VdoBloom rates Veo's content filter STRICT: the provider rejects sexual, violent, or otherwise policy-violating prompts and images before generating. VdoBloom doesn't promise unrestricted output on any model.
Is Veo 3.1 open source?
No — Veo is Google's proprietary model, accessed through its API, the same on VdoBloom as anywhere else.
What's the prompt limit for Veo 3.1?
5,000 characters — VdoBloom's platform default, since Veo doesn't have a shorter model-specific cap the way Kling (2,500) or Runway (1,800) do.
