Veo 3.1 Fast Guide: Half the Credits for Google’s Video With Sound
Google’s Veo models are best known for generating dialogue, sound effects and ambience along with the picture. Veo 3.1 Fast gives you that at half the credits of the full model: 8 credits for an 8-second clip. Here is how it differs from Veo 3.1, how to use it for drafting, and the limits to expect.
- Veo 3.1 Fast costs 8 credits for an 8-second clip with sound. Veo 3.1 is 16.
- Clips are always 8 seconds and 16:9 on PulseMotionHub.
- It needs the Pro or Studio plan and works from text or an image.
- A good use is to draft on Fast, then re-run keepers on Veo 3.1.
What It Is
Veo is Google’s video model family. Veo 3.1 Fast is described as the faster and more affordable version of Veo 3.1, with the same native audio generation at lower cost, suited to drafts and iterations. On PulseMotionHub it sits in the Premium tab and accepts a text prompt, with an optional start image.
A note on claims: we describe each model by how it is used on PulseMotionHub and what it costs. Quality varies by scene, so test your own prompt cheaply before committing credits.

A Draft-Then-Final Workflow
One Veo 3.1 Fast clip is 8 credits.
A Worked Cost Example
Say you want one finished 8-second clip with sound and are willing to try the prompt a few times. Three drafts on Veo 3.1 Fast cost 24 credits, which is $11.76 at the Pro credit price. Re-running the best one on Veo 3.1 adds 16 credits. The total is 40 credits, against 64 credits if all four attempts had been on the full model.
The saving only matters if your first prompts need adjusting, which is common. If you already know exactly what you want, going straight to the full model costs the same as one draft plus one final. Credits from a failed generation are refunded, so a technical failure does not add to the total.
Prompting for Veo
A chef plates a dessert in a quiet restaurant kitchen. Soft clatter of utensils, a gentle sizzle, low hum of the extractor fan. Slow push-in. Warm light. Rain falls on a city street at night. A woman under an umbrella says quietly, “It’s almost midnight.” Footsteps in puddles, distant traffic. Static shot, neon reflections. A sailboat glides across a calm bay at sunrise. Water laps gently against the hull, a gull cries. Slow tracking shot along the shore.Speech works best when short and in quotation marks. Keep the scene simple. See how to prompt sound and our camera glossary.
