Seedance 2.5 announced to generate 30-second 4K videos from up to 50 reference inputs
Story Overview
ByteDance unveiled Seedance 2.5 at the Volcano Engine Force 2026 conference, positioning the model as an advance over the prior version by targeting 30-second native 4K clips from a single prompt plus support for as many as 50 multimodal references. Conference reports describe improved editing controls such as subject swaps that keep motion and lighting intact, yet the system remains in pre-release with general access expected only in July.
Longer outputs and reference volume shift what creators can attempt in one pass
The jump from roughly 15-second clips and a dozen references in Seedance 2.0 to the new limits opens the door to multi-shot sequences without immediate stitching, though independent tests have not yet confirmed how well consistency holds across those lengths.
Public rollout timing leaves open questions about access and pricing
Announced as coming soon rather than live, the model still lacks confirmed details on API tiers, early-access programs, or subscription costs, so teams watching ByteDance’s seed.bytedance.com channel will need to wait for July updates before planning production use.
Many users praise Seedance 2.5 for its stunning 4K video quality and Hollywood-disrupting potential from simple prompts, while some express frustration that it remains far from easy full-feature film production.

one click filmmaking is here

@kimmonismus It's because of their data @kimmonismus Its from ByteDance which has TikTok. That's a massive video content ecosystem of training data.

@vicilah good call! Makes so much sense. However, Google has YouTube
Correction: Announced, not released. My bad! Thanks @koltregaskes
Seedance 2.5 released. It looks insane! Still trying to figure out where Veo 4 is and why nothing comes close to Seedance

@kimmonismus Same here waiting for veo 4

@kimmonismus They are running away with video performance at the moment!

@kimmonismus Veo is garbage, so seedance 2.5 looks exciting

@PaulGugAI and where is google? where is meta?

@revolaition That's the point, probably not.

@kimmonismus Amazing. Would a real top tier video production company do it better? Doubt it.

@Scobleizer yea end of the year well get 60 seconds. Robert how much can i pay for you to cameo in my seedance feature film?

@kimmonismus It was announced not released yet. It comes out early July.

@Web3__Youth Hmmm I do know a guy who can spin up a thousand Linux boxes in a few seconds.

@Web3__Youth Yeah. I remember spending hours to install on one windows box.

And yes yt shorts is big but I think the difference is that with capcut it helps them understand is the creation/editing data. The cuts/templates/effects/transitions etc. then TikTok shows what actually retains. So the edge is not just short form data but it’s the edit -> post -> watch loop. Hope that part makes sense @kimmonismus

@kimmonismus There is no veo 4

@JSFILMZ0412 It would be charity because I would do it for free.

@kimmonismus Not released, just announced. Released is early July.

@kimmonismus Yeah, this is just unbelievably good. Probably took a lot of work and a million iterations to get there, but wow.

@Scobleizer wow 😵
