Runway launches Seedance 2.5 with support for 50 character references per generation

Runway 上线 Seedance 2.5，支持 50 个角色参考

Runway upgraded its Seedance video model to 2.5, letting you reference up to 50 characters in a single generation to build multi-character scenes. Each clip can run up to 30 seconds with sound effects and dialogue, then be edited and extended as needed. The post doesn't mention pricing or generation speed.

Why it matters: Runway bumped character references to 50 and added 30-second clips with audio/dialogue — a substantive product update. No speed or pricing disclosed, and the post lacks hands-on testing, so the score stays at the featured threshold.
