Seedance 2.5
30 Seconds. 4K. One Generation.
Seedance 2.5 is ByteDance's most advanced video model — native 4K resolution, 30-second continuous clips, and up to 50 reference inputs in a single generation. With 20% sharper prompt adherence, tighter lip-sync, and region-level editing, it produces broadcast-ready video that holds up from the first frame to the last. Available on Pexo.

What Makes Seedance 2.5 Different
Native 4K, 30-second continuous generation, 50 reference inputs, region editing, and joint audio-visual synthesis — all in a single pass through Pexo.
Thirty Seconds in a Single Pass
Seedance 2.5 on Pexo generates a full 30-second clip natively — no stitching, no extension passes, no seams. A complete scene, ad, or story beat holds from the first frame to the last in one continuous generation. Characters, lighting, and motion stay consistent across the entire duration without the drift that plagues clip-and-extend workflows.
Feed It Everything. It Uses Everything.
Seedance 2.5 accepts up to 50 multimodal reference materials simultaneously — images, audio clips, video references, 3D white models, and style guides. The model incorporates all of them to control identity, motion, composition, and tone. This is a fourfold increase over Seedance 2.0's 12-input limit, giving you precise control over every visual and auditory dimension.
Broadcast Resolution From the First Render
Every generation from Seedance 2.5 outputs at native 4K — not upscaled, not interpolated. The model renders at full resolution from the start, which means fine textures, skin detail, and type-on-screen all resolve cleanly. No post-processing step, no quality loss. The output is broadcast-ready without touching another tool.
Change a Detail Without Regenerating the Whole Clip
Seedance 2.5 supports localized editing — isolate a region of a generated clip and modify it without regenerating everything else. Swap a background, change wardrobe, adjust a prop, or fix a facial expression while the rest of the scene stays locked. This turns what used to be a full re-render into a surgical fix.
Sound and Picture Generated Together
Seedance 2.5 co-processes visual and audio signals in the same latent space, producing native synchronization between onscreen actions and their corresponding sound. Lip movements match speech at the phoneme level with tighter accuracy than Seedance 2.0. Dialogue, ambient sound, and effects arrive locked to the frame — no layering step, no drift.

How is it different from Seedance 2.0?+
Seedance 2.5 doubles the maximum clip length (30s vs 15s), quadruples reference inputs (50 vs 12), adds native 4K output, introduces region editing, and delivers 20% better prompt adherence. It's a generation-level upgrade.
Do I need to know how to use Seedance to use Pexo?+
No. Pexo handles all model interaction behind the scenes. You describe what you want to make in plain language — Pexo takes care of the rest.
What kinds of videos can I make?+
Product ads, brand films, social reels, short stories, ASMR videos, music videos, and more. If you can describe it, Pexo can produce it.
Can I edit part of a generated video without starting over?+
