Seedance 2.5 Free AI Video Generator
Generate a Seedance 2.5 video in the browser with starter credits. Choose the model, inputs, duration and resolution first; the exact credit charge is shown before you submit.
Free means a real starter allowance, not unlimited generation. Current workspace output is 480p or 720p and 5–30 seconds; we do not advertise native 4K.

How the free Seedance 2.5 workflow works
New accounts receive a limited starter balance when the offer is active. The generator calculates the charge from resolution and duration before the task begins, so you can reduce cost without discovering a surprise after submission.
A submitted generation is asynchronous. If the provider confirms a task failure, the reserved credits are returned. If the provider is still processing or temporarily unreachable, the task stays pending rather than being submitted a second time.
- 01
Choose a workflow
Use text-to-video for a new shot, image-to-video for a controlled opening frame, or references for recurring visual identity.
- 02
Write one clear shot
Describe subject, action, environment, camera and timing. Avoid stacking conflicting camera moves.
- 03
Set duration and resolution
Start with 5–10 seconds at 480p while testing; move to 720p after the motion and composition work.
- 04
Review cost, then generate
The button shows the exact product-credit charge. Sign in only when you are ready to submit.
Product credits
What one generation costs here
Credits are the workspace billing unit. They are not the same as dollars charged by Kie or fal, and third-party provider prices may change independently.
| Setting | 5 sec | 10 sec | 15 sec | 30 sec |
|---|---|---|---|---|
| 480p · 6 credits/sec | 30 credits | 60 credits | 90 credits | 180 credits |
| 720p · 12 credits/sec | 60 credits | 120 credits | 180 credits | 360 credits |
Best way to use free credits
Validate the prompt at 480p and a short duration. Increase resolution or length only after the action, framing and camera direction are correct.
Prompt structure
Give the model a shot plan, not a bag of adjectives
The most useful prompt describes what changes over time. State the subject and action first, then camera behavior, environment, lighting and audio intent. For longer clips, use time ranges to separate beats.
10-second product shot
[0–3s] Macro view of a brushed steel watch on black stone; slow clockwise orbit, soft window reflection. [3–7s] The crown turns and the second hand begins moving; camera eases closer. [7–10s] Pull focus from the dial to the engraved logo; quiet mechanical clicks, no music.
Know before submitting
Current limits and truthful expectations
- This workspace currently exposes 480p and 720p output, not native 4K.
- Free starter credits are finite and may change; the visible account balance is authoritative.
- Reference mode accepts a practical subset in the browser even where a provider API may support more files.
- Generation time depends on provider queues, duration, resolution and current demand.
- Commercial use depends on your source rights, the output and the terms that apply to your account.
- SeedanceAI.dev is an independent service and is not ByteDance's official product site.
Common questions
Can I use Seedance 2.5 for free?+
You can use the starter credits shown in your account when that offer is active. The allowance is limited; each generation displays its credit cost before submission.
Does the free generator add a watermark?+
Watermark behavior can depend on the upstream provider and account plan. Review the generated file and the current plan terms before publishing; we do not promise a universal no-watermark result here.
Can Seedance 2.5 generate 4K video here?+
No. This workspace currently offers 480p and 720p. Upscaling is a separate workflow and should not be described as native Seedance 2.5 4K generation.
What happens if a generation fails?+
When the provider confirms a failed task, the reserved product credits are refunded. A task that is still processing is not treated as failed.
Is SeedanceAI.dev the official ByteDance website?+
No. SeedanceAI.dev is an independent product that uses configured third-party API providers.
