Seedance 2.5 Is Live on Aristotto

Seedance 2.5 is live: 30-second single-take video with native audio and 50 references. Save 46% on credits, same discount applies to Seedance 2.0.

Seedance 2.5 is ByteDance's newest video model, and it's a real generational jump from 2.0. It generates a full 30-second single-take clip in one pass instead of the short clips most models produce, reads up to 50 reference images, videos, and audio clips in a single generation, and renders native audio alongside the visuals. Because it's built for full scenes rather than single moments, structure your prompt in timestamped beats instead of one long paragraph: describe what happens from 0-5s, 5-15s, 15-25s, and so on, so the model follows a story arc instead of just guessing at the opening frame. Through December 20, every generation with Seedance 2.5 or Seedance 2.0 costs 46% fewer credits, automatically, on every paid plan. Not sure what to test? A lone climber in a bright red jacket reaches the jagged summit of a snow-capped peak at sunrise. The camera starts low-angle tracking upward as the climber plants an ice axe, then slowly orbits 180 degrees revealing an endless sea of golden-lit mountains and clouds below. Dramatic god rays pierce through mist, orchestral wind swell and crunching snow synchronized with each step. Cinematic 35mm film grain, volumetric lighting, epic wide aspect.
