Jimeng AI launched Seedance 2.5 with professional-focused upgrades: a
long-generation mode that can produce video clips up to 3 minutes; a web "smart
edit" mode for localized insert/delete/modify video tasks; multi-frame editing
that removes single-frame limits for fine clip-level adjustments; and new Maya
and Blender plugins to integrate 3D assets, green-screen footage and AI
content-production workflows.
