Veo 3.1 Fast AI Video Generator

What Veo 3.1 Fast is good at

Veo quality at a lower rate. Good prompt adherence.

The limit worth knowing

Less detail than the full model. Knowing it before the first run saves a wasted attempt.

When to reach for it

Mid-budget shots that still need Veo behavior.

Prompting Veo 3.1 Fast for a short take

Clips stop at 8 seconds, so write one shot with one camera move and a clear final frame. Veo follows prompts closely, so order the events as they should happen. For example: "paper boat drifts down a rainy gutter, camera lowers to water level, boat slips under a grate". Or "close-up of hands unwrapping a gift box, tissue paper lifts, a ceramic mug appears, warm living-room light". For a store page, try "running shoes on a wet track, camera circles at ankle height, morning mist". Start from the Slow push in, Product turn or Street at night preset.

Resolution, length and the jump to full Veo

Both 720p and 1080p cost 36 credits per second, so resolution does not change the bill. The catch is length: 1080p comes only as an 8-second clip at 288 credits. A 4- or 6-second clip renders at 720p for 144 or 216 credits. Frame 16:9 or 9:16, as there is no square option. Once a take works, rerun the same prompt on Veo 3.1 at 95 per second for more detail. For mostly physical action, Kling 3.0 at 27 is cheaper and runs to 15 seconds. Seedance 2.5 at 27 reaches 30 seconds with sound.
