Native 4K had been on [Seedance 2.5](https://aifilmhistory.org/entry/seedance-2-5)'s spec sheet since its June reveal, but the model creators could use stopped at 1080p. On November 11 it opened up across the platforms filmmakers work in: Pika launched it first, for drafting a take and finishing it in 4K, and Runway followed the same afternoon. Like [Seedance 2.0's 4K upgrade](https://aifilmhistory.org/entry/seedance-2-0-4k), the frames are generated at full resolution rather than upscaled.

The next day ByteDance went the other way with Seedance 2.5 Flash on Dreamina and BytePlus, close to the flagship's results at nearly twice the speed, at 480p and 720p, with clips up to 30 seconds and up to ten images, five videos and five audio clips as references. Between them, the two releases split the work the way productions already did: a fast tier for finding the shot, a 4K tier for the one that ends up in the film.
