What is the Seedance 2.5 AI Video Generator?
Seedance 2.5 is ByteDance's next-generation multimodal AI video model, introduced at the 2026 Volcano Engine FORCE conference. It is engineered for professional-grade content: a single generation produces a continuous, cinematic shot up to 30 seconds long, holding character identity, lighting, and camera motion steady across the whole clip. Seedance 2.5 works from a text prompt, a first/last frame image, or a set of multi-modal references — images, videos, and audio — that steer the result.
The headline upgrade is native audio-video co-generation: dialogue, foley, and ambient sound are produced together with the picture in one pass, so audio and motion stay locked in sync. Seedance 2.5 renders at 480p and 720p across 1:1, 4:3, 3:4, 16:9, 9:16, 21:9, and adaptive aspect ratios. On VO3 AI, Seedance 2.5 is available now for text-to-video and image-to-video — choose 480p for the most affordable output or 720p for maximum detail, at 5s, 10s, or 15s.
