Native 30s 4K Video
with Seedance 2.5
The next flagship video model from ByteDance Seed. Generate a full 30-second clip in native 4K with synchronized audio — steered by text, images, audio, 3D white-models, and up to 50 multimodal references — through a single Wiro API request.
What Seedance 2.5 Can Produce
Longer scenes, sharper detail, and tighter brand consistency — each generated from minimal input in native 4K. Examples below illustrate the kinds of outputs the model is built for.
"A 30-second product launch film — a sleek device rotates on a lit pedestal, the camera orbits in one continuous take, ambient studio tones swell as feature callouts resolve into focus."
16:9 · 30s · 4K"Cinematic concept trailer: a lone traveller crosses a rain-lit city, neon reflections rippling on wet asphalt. Score builds to a single held note as the title card lands."
9:16 · 20s · 4K"Packed arena, decisive match point. The crowd roars and falls silent on the serve. Native audio tracks every footstep, whistle, and gasp in sync with the action."
16:9 · 25s · Audio"From one product photo: a macro beauty shot in native 4K. Light glides across the surface, textures stay razor-sharp, 10-bit gradients render the packaging cleanly."
9:16 · 12s · 4K"A branded story scene assembled from character images, product shots, brand colors, and a 3D white-model layout — the model keeps every reference consistent across the shot."
3:4 · 18sWhat's New in Seedance 2.5
The biggest leap since Seedance 2.0 — longer scenes, native 4K, far more reference control, and pre-render planning.
Native 30-Second Clips in True 4K
Seedance 2.5 generates a full 30-second shot at native 4K — rendered at full resolution rather than upscaled from a smaller frame — with no stitching required. Add 10-bit color depth and you get smoother gradients and far more headroom for grading in post.
Keep Characters and Brands Consistent
Where the previous generation accepted a handful of references, Seedance 2.5 takes up to 50 multimodal inputs — images, text, audio, and video. Lock down characters, products, colors, logos, and styles so they stay consistent across every scene.
3D White-Model Preview
A new white-box preview generates a low-fidelity pass first — so you can lock scene layout, camera paths, and motion direction before committing to a full-quality 4K render. Fewer wasted generations, faster iteration, more predictable results.
Native Audio and Better Adherence
Audio is co-processed in the same latent space as the visuals, so speech, effects, and ambience land exactly on the action. ByteDance also reports around 20% better prompt adherence — meaning fewer generations before you get the shot you described.
