Seedance 2.5とは？
Seedance 2.5 is ByteDance's flagship AI video model, built for fluid, natural motion, strong character consistency, and multi-reference control. It handles text-to-video, image-to-video, and reference-to-video — anchor up to 9 images as @Image1…@Image9 in your prompt and the model keeps subjects, styles, and products consistent across the whole clip. First & last frame interpolation lets you steer a shot from a defined start to a defined end.
On animx you generate with Seedance 2.5 directly in the browser — no waitlist, no standalone plan. Pick the model, write a prompt, attach reference images or starting and ending frames, and export. Seedance comes bundled with Veo, Kling, Sora and the rest of the top models under one subscription.
