The long take against the 4K take, from the same family.
Seedance 2.5Both on starter and up. One plan, one pool of credits.
The short answer
Use Seedance 2.0 unless the shot needs what only 2.5 has. Seedance 2.0 costs about 40 percent less per second at every resolution, and it reaches 4K where 2.5 stops at 1080p. Seedance 2.5 is for single takes longer than 15 seconds, up to 30, and for reference sets bigger than 2.0 accepts: 30 images, 10 clips and 10 audio tracks against 9, 3 and 3. It also drafts at 480p and finishes the keeper in 1080p. Both generate sound, both are in the API, and both run on the same APImage plan.
