IT Home reported on October 22, citing Sina Tech, that Volcano Engine recently began the first round of enterprise user trials for its Seedance 2.5 4K model. Tied to specific projects, the model is being supplied to 20 studios and directors worldwide to explore the needs of high-end film and television productions intended for the big screen.
According to the introduction, beyond sharper image details, Seedance 2.5 4K emphasizes more nuanced and natural character performances and finer consistency in reference-based generation and editing. It is the most capable model in the Seedance 2.5 generation. The 4K version places greater emphasis on exploring high-end film and television needs. Of the 20 projects currently using it, the earliest could see a satellite TV broadcaster air an S-tier IP as soon as next month; the projects also include a film based on a major global IP.
IT Home noted that ByteDance first unveiled Seedance 2.5 at the FORCE conference on June 23, opened its API to leading enterprise customers on July 13, expanded access to ordinary developers on July 16, launched consumer access through the Jimeng website and mobile app on July 31, and formally opened commercial API access for Seedance 2.5 on August 7.
Seedance 2.5’s core upgrades focus on longer videos and precise control. The duration of a single video segment has increased from 15 seconds in version 2.0 to 30 seconds, making it suitable for scenarios requiring a complete narrative, such as short dramas and animated dramas. A new local refinement feature lets users modify a character’s face, clothing or scene props individually without redrawing the entire segment, reducing the cost of rework. In addition, the model supports native 4K output, with image details meeting commercial delivery standards.
