This site provides a web interface for the Seedance 2.5 model. You type a scene or upload an image, and it produces one continuous shot rather than stitching short clips together. The site mentions native 4K output with sound and support for many reference inputs.
Modes include text to video, image to video, first and last frame control and reference-based generation. You sign in to generate, and default settings start at lower resolution and short length, with paid plans for more.
