Short answer: Seedance 2.5 outputs single clips from 4 to 30 seconds at 480p, 720p, or 1080p. Longer 4K ceilings belong to Seedance 2.0 (about 4–15 seconds), not to 2.5. Pick duration and resolution in the generator, then check the on-screen credit estimate before you submit.
Open Seedance 2.5 to set length and resolution, then compare plan cards on pricing if you need more monthly credits.

What is the maximum length for Seedance 2.5?
Public product copy lists Seedance 2.5 output duration as 4–30 seconds per clip. That range applies across the published resolutions 480p / 720p / 1080p. The site does not publish a plan gate that blocks 30-second jobs on Mini–Pro; still confirm the selected duration in the UI before you pay credits.
| Model | Duration | Resolutions (public) |
|---|---|---|
| Seedance 2.5 | 4–30 seconds | 480p, 720p, 1080p |
| Seedance 2.0 (contrast) | 4–15 seconds | Can include up to 4K on that model line |
Does Seedance 2.5 support 4K?
No. Seedance 2.5 public guidance stops at 1080p. Any 4K mention on this site belongs to the Seedance 2.0 line (with its shorter ~4–15s window), not to 2.5. If your brief requires 4K, treat that as a different model choice—not an upgrade toggle inside 2.5.
How should you choose duration and resolution?
Start short when you are testing motion or dialogue; stretch toward 30 seconds only after a short clip looks stable. Higher resolution costs more credits per second on the on-screen estimate, so lock length first, then bump resolution.
- Lock Seedance 2.5 in the model picker.
- Choose a duration between 4 and 30 seconds.
- Pick 480p, 720p, or 1080p—never assume 4K on 2.5.
- Read the live credit estimate before submit.
- Compare monthly credit pools on pricing if one long job will burn most of a Mini balance.
How does length interact with plans and credits?
Mini–Pro subscriptions publish monthly credit pools (for example Mini 3,000 up through Pro 26,000 on the pricing cards). Yearly billing still releases credits monthly. Public pages do not replace the generator estimate with a fixed “N credits per second” promise for every mode, so trust the estimate for your exact length × resolution.
New accounts may receive sign-up credits enough for one test video when a grant is active; that is not a substitute for checking the estimate on a 30-second 1080p job.
What are the common questions about Seedance 2.5 video length?
How long can Seedance 2.5 videos be?
From 4 to 30 seconds per clip at 480p, 720p, or 1080p, per the product page and pricing FAQ.
Can Seedance 2.5 output 4K?
No. Public 2.5 guidance lists 480p / 720p / 1080p only. 4K belongs to the Seedance 2.0 contrast line, not 2.5.
Is 30 seconds limited to Pro plans?
Public pricing cards do not publish a Mini-only ban on 30-second Seedance 2.5 jobs. Confirm duration in the generator UI; credits and the estimate are the practical limits.
How does Seedance 2.0 length compare?
Seedance 2.0 is listed around 4–15 seconds and may include up to 4K on that model line. Seedance 2.5 trades that for a longer 4–30s window at up to 1080p.
Where should I set length before paying?
Open the product entry, set duration and resolution, read the estimate, then open pricing if you need a larger monthly pool.
Where should you go next?
Return to the product entry, lock a 4–30s clip at 480p/720p/1080p, and keep the pricing table open when you size a plan.
