Veo 3.1 常見問題
Does Veo 3.1 generate audio with the video?
Yes — Veo 3.1 natively synthesizes synchronized audio including dialogue, sound effects, and ambience in the same generation call.
What resolution does Veo 3.1 output?
Native 1080p generation with upscaling support to 4K (3840×2160). Aspect ratios include 16:9 and 9:16.
How long can generated clips be?
4, 6, or 8 seconds per generation. Scene Extension works once from a text-to-video result and cannot be chained.
Are generated videos watermarked?
All Veo outputs include an invisible SynthID watermark embedded in the pixel data, which persists through compression and resizing.
How is the audio generated?
Veo 3.1 generates native audio synchronized with the on-screen action, matching sound to the motion and events in the scene.
我應該先用邊個版本？
先選最平而且符合你質素要求的版本。大多數團隊會先用快速版本，之後再升級到 pro 用於正式生產。
