Seedance 2.5
The Seedance 2.5 API gives developers ByteDance Seed’s joint audio and video model, generating 4 to 30 seconds in one pass from text, a first frame, or up to 50 references across images, video, and audio. It edits selected regions, extends clips, and follows white-model and green-screen inputs. Atlas Cloud, an authorized U.S. reseller, adds a 480p draft mode, native 1080p finals, and enhanced 4K delivery with pay-as-you-go pricing.
