Seedance 2.5 is a new-generation AI video generator launched by ByteDance, focused on "generating a complete scene from a single prompt."
Purpose and positioning
- Text-to-video and image-to-video: input a text prompt or a reference image and output a continuous video.
- Designed for short-form content: the company says it is suitable for launch videos, ads, explainers, promotions, and other videos that need to be produced quickly.
Main capabilities
- 30-second single shot: generate one continuous 30-second video each time, with no manual stitching required.
- Native 4K and 10-bit color: the company says it renders in native 4K and 10-bit color, and the image clarity can meet large-screen needs.
- Joint audio-video generation: sound is produced at the same time as generation, and it can be downloaded as MP4 for direct publishing.
- Up to 50 reference inputs: up to 50 references can be input at the same time, including images, video clips, audio, 3D models, and style boards, etc., to maintain consistency of the subject, appearance, and character throughout the entire shot.
- Improved prompt adherence: the company says Seedance 2.5's prompt adherence is improved by about 20%, making the first generation closer to the request and reducing the number of retries.
- Official demos showcase cinematic camera movement, coherent scene changes, and high-fidelity output; the page says the demo clips were all generated from prompts or a single still image.
How to use
- Describe the scene in a prompt, or select a reference frame, and Seedance 2.5 generates a 30-second 4K shot.
- Reference images and reusable prompts can be combined to keep appearance and composition consistent across posts.
Use cases (according to official information)
