## AI 摘要

Seedance 2.5 终于发布了，实际效果远超预期。

它能生成 30 秒片段，但“长视频模式”可长达 3 分钟。SOTA 视频生成时长约 10 倍的跃升前所未有（此前我们大约每 6 个月翻一倍）。

这整支带音频的预告片，就是由它一次性生成的。

## 正文

Seedance 2.5 finally dropped， and it's actually way better than expected.

It can generate 30s clips but "long video mode" goes up to 3mins. A ~10x jump in sota video gen length is unprecedented （we were ~2x-ing every 6mos）

This entire trailer， with audio， was oneshotted by it.
