ByteDance Seedance 2.5 Hands-on: 30s Long Shots and Multimodal Control Praised

ByteDance's video generation model, Seedance 2.5, has sparked widespread testing attention across social media. Natively supporting the generation of up to 30-second single-shot videos, the model doubles the duration offered by most competitors while demonstrating exceptional visual quality and physical consistency in long takes.

已确认

• 核心能力：Seedance 2.5 can natively generate one-shot videos up to 30 seconds long and processes audio within the same generation step.
• 多模态参考：The model supports up to 50 multimodal reference inputs to ensure character and product consistency throughout the long video. For instance, when generating a Tokyo travel vlog, it strictly preserves the facial features, hairstyle, and body proportions of the person in the reference image.
• 实测表现：Multiple creators tested the model across various scenarios. @taherdhanera noted that the visual quality reached the realism of a "Hollywood movie clip"; @SimplyAnnisa and @eyishazyer successfully recreated a shaky, imperfectly framed "boyfriend perspective" daily vlog; in a test shared by @techhalla, a half-minute long take of an elderly woman speeding down a highway on a mobility scooter maintained perfect causal physical consistency.

为什么重要

• 时长突破：The 30-second continuous generation duration significantly surpasses the limits of current mainstream video generation models, unlocking new possibilities for long-form video creation.
• 多模态控制：Support for up to 50 reference inputs addresses the long-standing challenge of character and object consistency in video generation, enhancing its utility for commercial and narrative applications.
