Flagship Seedance 2.5 Pro AI Video Generator
ByteDance's flagship video architecture: Up to 30-second continuous shots, dual-keyframe morphing, 12 multi-reference inputs, and native multi-speaker audio.
What Is Seedance 2.5 Pro & How Does It Surpass Seedance 2.0?
Seedance 2.5 Pro is ByteDance's flagship generative video architecture engineered to break past the legacy 5-to-10-second limitation of earlier AI video engines. It delivers up to 30 seconds of continuous, high-definition 1080p footage in a single inference pass with native multi-speaker acoustic physics.
While Seedance 2.0 revolutionized AI video by introducing synchronized audio, Seedance 2.5 Pro elevates generative cinema into professional production workflows. With first-to-last frame dual keyframe interpolation, native 21:9 anamorphic widescreen, and an omni-reference attention module that accepts up to 12 character turnaround stills, Seedance 2.5 Pro enables true multi-shot cinematic narrative storytelling without face morphing or stylistic drift.
