Seedance 2.5

Seedance 2.5 is ByteDance's next-generation AI video model that generates native 30-second single-take clips at 4K resolution. Unlike earlier models that require stitching multiple shorter segments, 2.5 produces one continuous video with consistent lighting, character identity, and scene composition throughout.

The core appeal is multimodal reference input: you can combine up to 50 assets—text prompts, product photos, video clips, audio tracks, and more—in a single project. That means you can lock in a character's appearance, a product's exact look, brand guidelines, and a voiceover all at once, rather than juggling separate generations for each element.

It's built for creators, marketing teams, and production workflows where longer native clips reduce manual editing work. Product showcase videos, brand campaigns, social content, and ad production all benefit from having a full 30-second scene without visible seams. Local area editing lets you fix a specific detail—a gesture, a prop, a background element—without regenerating the entire clip. The tool runs in your browser with no installation required; new users get free credits on signup to try it out first.
