Method and every run: Seedance 2.5 at 1080p or Seedance 2.0 Pro at 4K: what the files contain
Same input: Seedance 2.0 Pro's 4K render, a patch of hull at three times size: the native 4K pixels against the same frame squeezed to 1080p and stretched back.
The extra detail is real and small: it shows when you crop, stabilise or deliver to a 4K screen, not at phone size. Seedance 2.5 has no 4K tier to compare.
