Veo 3.1 Fast AI Video Generator
Choose Veo 3.1 Fast when the project calls for the current Fast-labelled option and a text or one-/two-frame direction fits a 4, 6, or 8 second delivery.
Veo 3.1 Fast task directions
These local references help turn the current Veo 3.1 Fast input and control contract into a concrete task direction. They are not presented as output from this model.
Every card identifies whether it is a verified model-family example or a visual reference. Reference cards are not model benchmarks or before-and-after claims.
- Input contract
- Text prompt or compatible reference media: image (up to 2)
- Current controls
- Prompt length: Up to 5,000 characters · Duration: 4s, 6s, 8s options · Output resolution: 720P / 1080P / 4K · Framing: 3 aspect-ratio choices
- Selection boundary
- The Fast label is not a measured generation-time promise on this page. Its current documented controls match the Quality and Lite entries, so compare a different model only when the input or duration contract is different.

How to create a video with Veo 3.1 Fast
Keep the direction tied to one fixed-duration beat and make the prompt explain how the start frame, end frame, or text scenario should change over time.
- 1
Write one time-bounded change
Choose the four-, six-, or eight-second beat first, then state the visual change and camera behavior for that exact length.
- 2
Add reference media when needed
Add approved compatible media only when an existing frame, motion, or sound should guide the result.
- 3
Confirm duration and output controls
Confirm the current 4s, 6s, 8s options, 720P / 1080P / 4K, and 3 aspect-ratio choices in the workspace before generation.
- 4
Generate and review continuity
Before public use, inspect subject motion, camera changes, visible text, sound, and the final frame.
Checks before you create and publish
- Treat the workspace as current
- Model availability and settings can change. Use the options shown in the current workspace before you submit.
- Use approved source media
- When you upload images, video, or audio, confirm that you are allowed to use and publish it for the current project.
- Review the generated video
