What Is Seedance 2.5?
Seedance 2.5 is ByteDance's joint audio-video generation model, released on July 31, 2026. As of September 17, 2026, it is the latest Seedance model confirmed in ByteDance and BytePlus model information.

On Seeora, it is available for text, frame, and image-reference workflows at 480p or 720p.
- One Generation, a Fuller StoryPlan setup, action, scene changes, and a resolution inside one clip instead of stitching together a stack of disconnected shots.
- References With Clear RolesUse images to guide characters, products, locations, props, or style, then call them out directly in the prompt.
- Picture and Sound TogetherGenerate synchronized audio with the video when the scene needs dialogue, ambience, effects, or music.
Seedance 2.5 Core Features
The model expands creative control with video and audio references, 30-second generation, and targeted editing. This generator currently exposes text, frame, and image-reference workflows.
Reference Images, Videos, and Audio Together
Seedance 2.5 can use up to 30 images, 10 video clips, and 10 audio clips in one generation. Video references can guide motion, camera language, composition, and visual effects, while audio references can shape rhythm and sound. The model can also generate video from an audio reference alone.
- Use video references for movement, camera work, composition, and effects
- Use audio references alone or alongside images and video
- Combine as many as 50 reference assets in the full model workflow
Create a 30-Second Story in One Pass
Build a beginning, development, turn, and finish into one generation. Seedance 2.5 improves continuity across scene changes and shot transitions, helping characters, visual style, and audio stay connected throughout a longer sequence.
- Choose any duration from 4 to 30 seconds in this generator
- Plan multiple shots and scene changes inside one prompt
- Maintain a consistent audiovisual language across the sequence
Edit a Moment Without Rebuilding the Whole Video
Seedance 2.5 supports timestamp-level changes to audio and video in its broader model workflow. Creators can target a specific moment, character, camera perspective, or green-screen element while preserving the surrounding sequence.
- Target changes at a specific timestamp
- Refine characters, perspective, or individual visual elements
- Preserve continuity outside the edited moment
