Veo 3.1 generates AI video from text and images at up to 4K with audio
Veo 3.1 is a video generation model that creates 4-8 second clips from text prompts or reference images. It supports 720p, 1080p, and 4K resolution with optional AI-generated audio. Use text-to-video for prompt-led scenes or image-to-video when visual references need to guide the output.
Write a prompt up to 1000 characters describing subject, action, camera, and style. Output at 720p, 1080p, or 4K.
Upload up to 3 reference images. Frame mode uses 2 images as start/end frames. Reference mode uses 3 images for style guidance.
