The tech industry is witnessing a new round of efficiency revolution. The Seed team under ByteDance has officially launched the Seedance2.5 audio-visual joint generation model, which focuses on the "one-shot filming" capability, and comprehensively empowers multiple industrial scenarios.
In terms of narrative expression, Seedance2.5 extends the single-generation duration from 15 seconds to 30 seconds and supports seamless extension over multiple rounds, making complex storylines more coherent. At the same time, the model has deeply refined materials, lighting, and skin texture, effectively reducing the plastic feel of traditional generated videos and presenting a more realistic, camera-like quality.
Regarding diverse creative needs, this version significantly enhances the multimodal reference function. Creators can input up to 30 images, 10 video clips, and 10 audio segments in a single session. The addition of white model references and lighting control mechanisms makes physical lighting and motion trajectories more realistic and stable.
Additionally, Seedance2.5 has made fine-tuned upgrades in post-editing and controllability. Users can make targeted adjustments to details such as the visual perspective, camera movement rhythm, and green screen background through timestamps, thereby reducing the cost of post-production editing. Currently, the model is gradually launching on platforms such as Ji Meng AI and Dou Bao Professional Edition, with API services also expected to be available on Huoshan Fangzhou soon.
