Veo 3.1 Fast is Google's flagship video model from DeepMind, standing out among all competitors with one unique feature: it generates video with native sound. All other AI video models create only visuals — sound has to be added separately in a video editor. Veo 3.1 understands the description of the sound accompaniment directly in the prompt and generates audio simultaneously with the image.
This means that a beach scene will have the sound of waves and seagulls, rain in the city will have the characteristic noise of raindrops on cobblestones, and a narrator in the frame will synchronously 'speak' the specified speech. The quality of native audio is already sufficient for social media content and promotional materials.
In addition to sound, Veo 3.1 Fast features realistic motion physics and high-quality processing of complex scenes. The cost of 40 credits per video reflects the model's uniqueness — for content where sound without post-processing is important, this is the tool of choice.
