## What Seedance 2.5 Text to Video does

Use it for multi-beat scenes, product shots and short ads written as text. Set duration from 4 to 30 seconds, or -1 to let the model choose, ratio (adaptive, 21:9, 16:9, 4:3, 1:1, 3:4 or 9:16), resolution, generate_audio and seed. It takes no image: Seedance 2.5 Image to Video animates a picture and Reference to Video keeps a character.
