About Seedance 2.5
Seedance 2.5 comes from ByteDance's Dreamina team and specializes in long-form coherence: a single still becomes up to 30 seconds of continuous, stitched-free motion with synchronized native audio — the longest single-pass clips of any model on img2.video (Vidu Q4 reaches 16s, Kling 10s, Veo 8s).
On img2.video you run it through the same simple workflow as every other model: one photo, one prompt, clean MP4 out — with optional generated audio. We expose image + prompt generation only, in line with our Acceptable Use Policy.

Seedance 2.5 FAQ
What is Seedance 2.5?
Seedance 2.5 is ByteDance’s long-form image-to-video model (Dreamina family). Its signature capability: it animates a single still into one native 30-second clip — continuous, coherent motion with synchronized audio, no stitching or drift from gluing short clips together.
Why 30 seconds matters?
Most models generate 5–10 seconds, so longer stories need stitching multiple clips — visible seams, drifting characters. Seedance 2.5 generates the whole scene in one pass: characters, lighting and audio stay consistent start to finish.
How much does Seedance 2.5 cost?
On img2.video it starts at 65 credits for a 5-second 480p clip; a full 30-second 480p clip is 365 credits, 720p from 135 credits for 5 seconds. Audio is included at no extra cost. The exact price always shows before you generate.
Does Seedance 2.5 have audio?
Yes — dialogue and sound effects are generated synchronized with the video, at no additional price. Toggle it in the generator.
Seedance 2.5 vs Vidu Q4 vs Veo 3.1?
Seedance 2.5 for the longest single clips (30s); Vidu Q4 for 16s with 4K; Veo 3.1 for maximum polish in 8s. All run side by side here — see our model comparison.
Is it good for beginners?
The workflow is the same as every model here: upload one photo, describe the motion, generate. For quick cheap tests, draft your prompt on Seedance Mini or Grok first, then render the keeper at 30 seconds.
