It produces 4-15 second clips at 480P or 768P (no 2K) with native synchronized audio. It accepts a text prompt plus optional first-frame and last-frame images, and up to 9 reference images, 3 reference videos, and 3 reference audio clips, and supports text-to-video, image-to-video, first-and-last-frame, and reference generation. It does not yet support the adaptive aspect ratio, so a concrete ratio must be specified.
