Volcano Engine launches Seedance 2.5 4K video model with Draft preview mode

火山引擎 · wechat · 2026-10-23

Volcano Engine unveiled Seedance 2.5 4K, trained specifically on facial expressions, subtle motion and fine picture detail — billed as the strongest model in the Seedance 2.5 generation.

It adds a Draft mode: users iterate cheaply on 480P previews to nail storyboards and shots, then render a final 4K cut with 10-bit color depth. The model also better preserves quality and consistency of uploaded references, including small text on posters and packaging. Currently limited to select enterprise customers, with wider availability possible later.
