Dreamina Seedance 2.5

Dreamina Seedance 2.5 is an advanced video generation model developed by ByteDance Seed. Building upon the unified multimodal audio-video joint-generation architecture of its predecessors, Seedance 2.5 introduces significant capabilities tailored for complex, long-form storytelling and precise creative control. The model supports native generation of up to 30 seconds of continuous video in a single pass while maintaining consistent lighting, shadows, and motion dynamics.

A primary architectural advancement in Seedance 2.5 is its expanded Omni Reference system, which allows creators to ingest up to 50 multimodal inputs—including images, video clips, audio tracks, and style references—in a single generation task. It also features precise timestamp prompting and fine-grained editing capabilities that permit specific region modifications within existing frames without disrupting the surrounding narrative context. Designed for both commercial production and creative workflows, the model incorporates tools for timeline extension, professional pipeline support, and joint audiovisual rendering.
