ByteDance's Seedance 2.5 Delivers Native 4K Video With Physics-Aware Motion and Multimodal Control

ByteDance has released Seedance 2.5, a significant upgrade to its AI video generation model featuring native 4K output, 30-second generation duration, and physics-aware rendering that preserves detail across challenging motion scenarios. The model, available through Higgsfield's aggregator platform, generates videos with 10-bit color depth—offering over a billion colors compared to traditional 8-bit's 16 million—and includes integrated audio synthesis matched to on-screen action.
