Seedance 2.0
ByteDance's Seedance 2.0: native audio, camera control that follows direction, and up to 4K on High.
What is Seedance 2.0?
Seedance 2.0 is ByteDance's video model from the Seed team, launched on February 12, 2026.
It generates video and synchronized audio together and responds well to camera direction written into the prompt. On Flashloop you pick Fast for 480p or 720p drafts or High for 1080p and 4K, with clips up to 15 seconds.
Motion is where it stands out. Push-ins, pans and tracking shots tend to happen the way you write them, and physical action (a punch landing, fabric tearing, something heavy hitting the floor) carries more weight than it did in Seedance 1.5 Pro. Audio comes out of the same pass, with music, ambience and voices in sync with what is on screen. ByteDance also builds Seedance 2.0 into its own editors, CapCut and Dreamina.
On Flashloop you can anchor a shot with up to 7 reference images or with a first and last frame, but not both at once. If you need a single take longer than 15 seconds or a much bigger reference set, Seedance 2.5 is the newer model; if you need the highest resolution in the Seedance family, 2.0 on High is still the one that reaches 4K.
