Seedance 2.5 (also known as 씨댄스 2.5, 시댄스 2.5) is a new-generation AI video model, with its official website at https://seedance2-5.app/。据官方介绍，其核心定位是“用一条提示词生成 30-second 4K cinematic video." Users can get 16 free credits upon registration, and no credit card is required.
Key capabilities
- Native 30-second 4K video generation, with no need to stitch short clips; the company states this will not cause a decline in image quality or continuity at the seams.
- Simultaneous audio generation.
- Up to 50 multimodal references, including images, videos, and audio.
- Multi-shot storytelling, allowing multiple scenes, camera movements, and transitions to be arranged in a single prompt.
- Maintains character, product, and brand consistency across all frames.
- Supports using a 3D white model for fine creative control.
- Provides an API to integrate video generation into existing workflows and supports native 4K export.
Officially showcased usage methods The official website provides a variety of reference usage examples: combining multiple reference images to create composite effects such as outfit changes, fisheye, and flash overlays; combining the character motion from one video with the orbiting camera movement from another video; extending a video while maintaining consistency; using precise cinematographic keywords to generate MV-level content; replacing a person in a video while preserving the original action and motion; using multiple reference images to create a continuous one-take tracking shot; and providing only images and audio as inspiration to let AI generate an emotional narrative video.
Workflow (official three-step explanation)
- Upload reference images and clips; multiple input types can be combined to increase creative freedom.
- Write prompts using @ mentions and natural language to specify the purpose of each asset, for example, "character reference @Image1, use @Video1 for camera movement."
- Choose settings and let the model generate, obtaining results that can be shared or further refined.
Applicable scenarios The company states it can be used for film, advertising, animation, social content, and more. All paid plans include a commercial use license.
Other information The official website has an FAQ section covering product definition, video length and resolution, credits and commercial use, developers, what can be created, whether editing skills are required, whether the names are equivalent, and other questions, but the page does not provide the specific answers. Details beyond each pricing tier, specific credit consumption rules, resolution and duration limits, as well as differences between plans, are not currently provided in the materials.
