Volcano Engine's website shows Seedance 2.5 now supports native 1080p video
generation and the API is live. Seedance 2.5 is positioned for "cinematic
long-form narrative" with improved realistic imagery and long-shot capability;
it previously supported 480p and 720p. The 1080p upgrade increases image clarity
and post-production flexibility, expanding professional use cases. Volcano
Engine launched a first-month promotional price: 1080p image-to-video pricing
drops from 3.7 yuan/sec to about 2.7 yuan/sec through Sep 17.
