[Strengths] It accepts up to 9 reference images and optional reference audios, with 4-15 second duration, 768P or 2K output, and optional aspect ratio defaulting to 16:9. [Best For] Highly recommended for: character or style consistency from stills, product look references, multi-image subject guidance, and prompt-driven scenes featuring a referenced subject. [Limitations] Do NOT use this model for first or last frame transitions or when the primary input is a reference video. prompt, duration, resolution, and reference_images are required.
