Vidu Q4 Image to Video turns one start image and an optional motion prompt into a 3–16 second clip at 540p up to 4K. Your image sets the opening frame, so subject, setting and aspect ratio carry through while the prompt directs movement and camera.
Vidu Q4 Reference to Video combines a prompt with up to 12 reference images and 3 voice clips into 3–16 second videos at up to 4K. Tag each reference in the prompt to keep characters, products and places recognisable, with optional generated audio at no extra cost.
