ByteDance Seedance 2.5: 30-second one-take AI video with multimodal refs
ByteDance Seed launched Seedance 2.5, its next-generation video creation model built on Seedance 2.0’s unified multimodal audio-video architecture. The model generates high-quality 30-second audio-video clips in a single pass with multi-round extensions, stronger shot transitions, and upgraded multimodal referencing—up to 30 images, 10 video clips, and 10 audio clips in one generation, including clay-render, motion, and creative references. Seedance 2.5 is rolling out on Jimeng AI and Doubao Pro, with API access coming via BytePlus ModelArk.
