What is Seedance 2.5?
Seedance 2.5 is a web-based AI video generator that produces up to 30-second single-segment videos with coherent scenes.

Outputs are videos up to 1080p resolution in multiple aspect ratios (16:9, 4:3, 1:1, 3:4, 9:16, 21:9, Adaptive). The tool is developed by Seedance and runs entirely in the browser.
