Seedance 2.5 — next-generation video and audio generation
Seedance 2.5 is already live on Unitool. A unified multimodal architecture for joint video and audio generation: text, images, audio and video go in, up to 30 seconds of a single take with sound comes out. Seedance 2.0 stays in the same chat, one tap away.
Seedance 2.5
Video and audio are generated in a single pass — with precise audio-visual synchronization. Mixed multimodal references, targeted edits of a finished clip and a cinematic result with no post-processing.
Video + audio together
Native audio generation synced with the video — dialogue, rhythm and effects match the motion on screen.
Multimodal references
Mix text, images, video and audio — up to 30 images, 10 clips and 10 audio files in a single prompt.
Director-level control
Control performance, lighting, shadows and camera movement — from idea to final shot.
What's new in Seedance 2.5
ByteDance's next-generation professional multimodal model: longer storytelling, richer references, precise editing and multilingual creation.
30 seconds in a single shot
One continuous clip up to 30 seconds instead of 15 — a whole scene, coherent camera movement and a complete story with no stitching in post.
More references
Images, video and audio in one request — the model holds up to 50 assets and carries complex ones accurately: packaging, 3D models, brand identity.
Controllable editing
Change one element of a finished clip while the rest of the frame stays intact. A scene can also be extended, keeping characters and camera choreography.
Prompts in 10+ languages
Native generation in English, Spanish, Portuguese, Indonesian, Japanese, Malay, Thai, Arabic, Vietnamese and Korean — with tighter instruction following.
