Prepare character assets
Create or reuse real-person and virtual-human Asset IDs when a character has to look the same across shots.
Seedance video studio
Seedance 2.0 & 2.5 online video generator
YingTu lets you generate videos online with Seedance 2.0 (Fast, Mini, Standard) and Seedance 2.5. Add your LaoZhang SeeDance2-group key, write a prompt, add reference images or audio if you need them, and submit. Tasks run in the background, so closing or reloading the page does not stop them; checks resume when you return, and finished MP4s can be played or downloaded. In our 2026-09-25 tests a 480p 4-second clip took 86-136 seconds and cost about $0.27 (Fast) to $0.50 (2.5).
No entrance password: the studio is open to everyone. Submitting a task still needs a valid Seedance key, and this public page never exposes your key, private assets, task details or generated files.
Three jobs, one studio
Set up the video
Combine a prompt with reference images, optional audio and character assets, then pick model, resolution, aspect ratio and length.
Track every task
See queued and processing states, reopen recent tasks at any time, and review the MP4 as soon as it is ready.
A testing order that saves money
Prove the shot with the smallest input first. Add character assets or more references only when they actually improve control.
- 1
Add a Seedance key
The studio opens without a key. Before you submit a video or asset request, paste a Seedance-enabled key under “API Key”.
- 2
Start with the minimum input
Write the shot prompt first. Add a reference image, audio file or character Asset ID only when the scene needs it.
- 3
Pick settings and submit
Choose model, resolution, aspect ratio and length in the interface, then submit one small test task.
- 4
Watch progress, review the result
Follow progress in the task list. When it finishes, check motion, character consistency, framing, audio and the file itself before running more.
Portrait asset API documentation
Create virtual-human assets, or real-person assets approved by the person themselves, with a LaoZhang API key, then reuse the asset:// URI across Seedance video generations.

Once it is Active, pass its asset:// URI as a reference image to keep the same character consistent across videos.

Seedance 2.0 / 2.5 price and speed (measured)
Billed by tokens: tokens ≈ duration × width × height × 24 / 1024. The table shows generation time and settled cost measured on 2026-09-25 with a SeeDance2-group key. Failed tasks and parameter errors are not billed; result links expire after about 24 hours.
| Model | Price per 1M tokens | Max resolution / length | Measured | Measured cost |
|---|---|---|---|---|
| Seedance 2.0 Fast | $6.66 | 720p · 4–15 s | 480p · 4 s · done in 86 s | ≈ $0.27 |
| Seedance 2.0 Mini | $4.14 | 720p · 4–15 s | 720p · 4 s · done in 87 s | ≈ $0.36 |
| Seedance 2.0 Standard | $8.28 | 1080p · 4–15 s | 720p · 5 s ≈ 2–5 min (docs) | ≈ $0.90 (720p 5 s) |
| Seedance 2.5 | $12.60 | 1080p · 4–30 s · mov output | 480p · 4 s · done in 136 s | ≈ $0.50 |
Long 30-second clips usually take more than 5 minutes. The YingTu workspace keeps checking in the background, so closing the page does not stop the task.
Seedance FAQ
Who makes Seedance? Is it a Chinese model?
Yes. Seedance is ByteDance’s video model family. YingTu calls it through LaoZhang API, so you use it in the browser with a LaoZhang key; you don’t need a ByteDance or Volcano Engine account.
Is Seedance 2.0 available now?
Yes. Seedance 2.0 Fast, Mini and Standard plus Seedance 2.5 are all available in this studio as of 2026-09-25. You need a LaoZhang key from the SeeDance2 group to submit tasks.
How long does a Seedance video take?
Measured on 2026-09-25 at 480p 4 s: Fast 86 s, Mini 87 s (720p) and 2.5 136 s; 30-second clips usually take more than 5 minutes. Tasks run in the background, so you can close or reload the page and checks resume when you return.
How much does a Seedance 2.0 / 2.5 video cost?
Billing is by tokens. Measured 480p 4 s clips cost about $0.27 on Fast and $0.50 on 2.5, and a 720p 4 s Mini clip about $0.36. Failed tasks and parameter errors are not billed. Video is not covered by the YingTu $0.1 free image credit.
The page says a status check failed. Did the task fail?
No. A failed check only means the latest status was temporarily unavailable (network or upstream busy), and it is retried automatically. A task is marked failed only when the upstream service reports failure; you can also cross-check in the LaoZhang task log.
Do I need a password to use the Seedance studio?
No. The guide and the studio are open to everyone. You only need a valid Seedance-enabled key when you actually submit a task.
What can I do before adding a key?
You can review the supported inputs, model settings, task flow and privacy notes. Nothing is submitted or billed until you add a valid key and choose to run a task.
Is Seedance free on YingTu?
No. The YingTu $0.1 free credit covers image models only. Seedance is billed by tokens from your own LaoZhang account.
What inputs can I use?
A prompt is required. You can add reference images, reference audio, and real-person or virtual-human Asset IDs. The interface and the API response show the exact limits.
Where are my recent tasks saved?
The video task list is saved in your current browser, so clearing browser data or switching devices may remove it. Real-person and virtual-human Asset IDs are different: after Google sign-in they are saved to your account.
