testingcatalog · x · 2026-07-23
ByteDance’s Dreamina Seedance 2.0 4K is described as a native 4K video model that does not upscale from a lower resolution first.
- It takes text, image, video, and audio references.
- It supports video editing and video extension.
- It runs through the BytePlus ModelArk API.
The quoted follow-up says it is already capable of production-grade output, and mentions Neill Blomkamp’s 13-minute sci-fi horror short Nightborne as an example made with Seedance 2.0 4K.
