Seedance 2.5 creates seamless 4K AI videos with multimodal references and fast partial editing.
Seedance 2.5 Developed by ByteDance’s Seed team, Seedance 2.5 is an upgraded AI video model succeeding Seedance 2.0. It generates seamless 30-second native 4K videos without manual splicing. Each project supports up to 50 multimodal references including text, images, audio and 3D files to unify visual styles, characters and lighting and avoid visual drift. It features partial editing to adjust target areas without full re-rendering, plus exclusive 3D white-model preview for industrial spatial simulation. Running fully on browsers without local GPUs, it covers short videos, brand ads, e-commerce showcases, industrial simulation and digital human creation. Now in enterprise beta, it will launch publicly in July 2025.
