What Seedance 2.5 is good at
Audio in sync with the picture
Sound effects, ambience and speech are generated with the video. You can still switch sound off when you want a silent clip.
Your photo's shape is kept
Unlike Seedance 2.0, its photo-to-video mode follows the shape of the photo you upload, so a tall picture stays tall.
All four ways to start
Text, one photo, a first and last frame, or up to three reference photos to keep a character or product consistent.
