Recently, the ByteDance Seed team officially launched the next-generation video creation model Seedance 2.5. As an audio-visual joint generation model that focuses on "one-shot filming," the new version has made breakthrough upgrades in three core dimensions: long narrative, multi-modal references, and post-editing, comprehensively empowering multiple industry scenarios such as film, advertising, education, and industry.
In terms of video length and narrative expression, Seedance 2.5 has achieved a qualitative leap. The single generation duration has been significantly increased from 15 seconds to 30 seconds, and it supports seamless extension over multiple rounds, allowing complex storylines to unfold coherently. To address the common industry pain point of "greasiness," the model has undergone deep optimization on materials, skin texture, lighting, and saturation, effectively reducing the plastic-like feel of traditional generated videos and delivering a more realistic cinematic quality.
For complex creative needs, Seedance 2.5 has upgraded its multi-modal reference capabilities. Users can now input up to 30 images, 10 video clips, and 10 audio segments as reference materials in a single session. Additionally, the introduction of white model references and lighting control functions allows for more realistic spatial structure, motion paths, and physical lighting, greatly enhancing the stability of group storytelling and multi-subject interaction.
Moreover, the model also performs outstandingly in editing and controllability. The platform supports precise content editing through time stamps, enabling creators to make targeted modifications to aspects such as visual perspective, camera movement rhythm, and physical effects rendering under green screen backgrounds, thereby significantly reducing the cost of repeated generation and post-production splicing.
Currently, Seedance 2.5 is gradually being launched on platforms such as Ji Meng AI and Dou Bao Professional Edition. API services will also be available on Huo Yan Fang Zha within a short period, continuously providing efficient AI video generation solutions for a wide range of creators and industry ecosystems.
