ByteDance announced Seedance 2.5, an AI video generator that can produce up to 30 seconds of footage in a single generation using up to 50 multimodal reference materials including images, videos, and audio. The model succeeds Seedance 2.0, which was limited to 15-second videos. The service is scheduled for official release in early July 2026 after enterprise testing.
ByteDance unveiled Seedance 2.5 at the FORCE Power Conference hosted by its cloud unit Volcano Engine. The model extends single-generation video length from 15 to 30 seconds and accepts up to 50 reference materials-images, video clips, and audio-to maintain consistency across multiple characters and scenes. ByteDance says the new version also improves editing control, allowing users to modify content while preserving overall style. The AI video creation service Renoise has already announced plans to offer Seedance 2.5. A public release is expected in early July 2026 following global testing with enterprise customers, though pricing, API details, and regional availability have not been disclosed.
