Extend Video API Pricing
SD 2.0 Extend Video continues an existing SD 2.0 generated video seamlessly. Provide the original request ID and an optional prompt to guide the extension — the model preserves visual style, motion, characters, and audio consistency across the new segment. Optional image, video, and audio references can be supplied to steer the extension: user-supplied references map to @image2…@image9, @video1…@video3, @audio1…@audio3 in the prompt (the source video's last frame is always @image1).
