Seedance 2.5 supports video generation from four to thirty seconds, together with text-to-video, image-to-video, and multimodal reference workflows. Brand storytelling often benefits from small observations because they allow the product to belong naturally inside the scene. Seedance 2.5 can generate up to thirty seconds in one pass, which makes this kind of connected arc more practical to explore. A camera reference can demonstrate pace and spatial behavior, while product and location images determine what appears in the scene. Seedance 2.5 brings longer generation, broader multimodal reference capacity, more precise reference understanding, and stronger editing into one workflow.
