When the screen is big, the render is 2.0
Seedance 2.0 4K exists for the deliverables that forgive nothing: TV spots, trade-show walls, cinema pre-rolls, billboard loops — native 4K, rendered, not upscaled. The 2.0 generation’s prompt adherence means the scene you briefed is the scene on the big screen, per render.
4K: native or upscale?
Two honest paths on OpenClips: render native on 2.0 4K when text, logos and fine texture must survive scrutiny; or render 1080p on Seedance 2.5 and apply the in-app Upscale 4K skill when the content is organic and forgiving. Native wins on graphics; upscale wins on budget. Either way, draft the shot cheap on Hailuo 02 first, finish it once — the library keeps every take, and the rate card on the pricing page shows the math for both paths.
