“Aerial drone shot flying low over turquoise ocean waves crashing against dramatic coastal cliffs at sunset, golden hour light painting the spray, cinematic travel film style, smooth sweeping camera movement”

What is Seedance 2.5?
Seedance 2.5 (seedance2.5) is ByteDance’s long-form video generation model. Where most frontier models cap out at 5–10 seconds, Seedance 2.5 sustains coherent motion, consistent subjects and stable camera work for up to 30 seconds in a single generation — no stitching, no frame interpolation tricks.
That makes it the workhorse for content that needs room to breathe: travel films, establishing shots, product stories, ambient loops and music visuals. Renders come out as clean MP4s at 480p or 720p, in the aspect ratios modern platforms demand — 16:9 for YouTube, 9:16 for Shorts and Reels, 1:1 for feeds.
On Viddra, Seedance 2.5 runs behind one unified API with per-second billing and dual upstream channels (fal + Volcengine) for high availability. Click Generate to drive it from the browser playground, or POST straight to the API — no ByteDance or Volcengine account required.
