Wan 3.0 is Alibaba's flagship video model, and it does the whole job in one pass: it renders the picture and synchronized audio together, so dialogue, ambient sound, and music arrive with the video instead of being dubbed in later.
Drive it three ways: text-to-video, a first frame (with an optional matching last frame), or reference-to-video using up to ten images, five videos, and five audio clips to lock subjects, motion, and sound. Clips run 2 to 30 seconds at up to 1080P. Prompt it like a shot list: timed beats, named references, and specific sound cues.
