Overview
Seedance 2.5 is the newest release in the Seedance family of video generators and the successor to Seedance 2.0. It is a unified multimodal model that accepts text, image, audio, and video as input, and produces native video with synchronized audio in a single generation pass.
Compared with Seedance 2.0, Seedance 2.5 brings longer single-shot duration, larger reference capacity, higher resolution, and tighter prompt control.
Features
Seedance 2.5 generates up to 30 seconds of video in a single run, doubling the 15-second limit of Seedance 2.0. Longer native clips reduce the need to stitch multiple short segments, producing more coherent motion and narrative flow.
A single generation can include up to 50 reference assets, any mix of images, videos, and audio. This is the largest reference capacity in its class. Provide a cast of characters, products, or style references and let the model orchestrate them into a single scene.
Generations can be produced at up to 3840 × 2160 natively, without an external upscaling step. Output is suitable for direct use in advertising, e-commerce, and short-form content pipelines.
Subjects, actions, layout, and stylistic instructions are followed approximately 20% more reliably than in Seedance 2.0. Better adherence reduces the number of regenerations needed to land on a usable result.
Combine text prompts with image, video, and audio references in a single generation. Output videos include a native audio track synchronized with the visuals.

02
Write your descriptive prompt in Seedance 2.5. Choose your output resolution (480p, 720p, or 1080p), select an aspect ratio (16:9, 9:16, 21:9, or adaptive), adjust the duration slider up to 30 seconds, and toggle Generate audio on or off.
03
Click generate to create your scene using the Seedance 2.5 AI video generator. To build multi-scene narratives, enable the Return last frame toggle to automatically pass the final frame into your next prompt pass for continuous storytelling.
Seedance 2.5 is an AI video generator built for creators and production teams. Write a prompt, attach up to 50 multimodal references, and get a native 4K video with synchronized audio, all from a single generation.
