The fast version: to generate a Seedance 2 video from the US, you don't need the Dreamina app or a Chinese phone number. Open a browser generator, pick a mode, write a prompt, check the credit cost, and hit generate — about a minute of setup. Here's the full walkthrough, the settings that actually matter, and what to do when it "won't work."
What you need first
Not much. A browser and an email address (or a Google account) — that's the whole barrier. The official Dreamina route has been reported to require a Chinese mainland phone number, which is where most US users get stuck. A web generator like seedance-21.app skips that: you sign in, you get credits, you generate. No app install, no region workaround.
Step by step
1. Pick a mode. Choose text-to-video (describe a scene from scratch), image-to-video (animate a still you upload), or Fast draft for quick, lower-cost tries. Seedance 2 is the standard quality; Seedance 2 Fast trades some fidelity for speed and a lower credit cost.
2. Write your prompt. Describe the shot like you'd brief a camera operator: subject, action, setting, camera move, mood. For image-to-video, upload your reference and spend the prompt on the motion you want ("slow push-in, hair moving in the wind"), not on re-describing what's already in the frame.
3. Set resolution and length. You can generate at 480p, 720p, or 1080p, with clips from 4 to 15 seconds. Drafting an idea? Start at 480p — it's cheap and fast. Final cut? Bump to 1080p once the prompt is dialed in.
4. Preview the credit cost. The exact credit cost shows up before you run, so you're never guessing. Higher resolution and longer duration cost more; Fast mode costs less.
5. Generate and download. Submit and wait for the clip. If a generation fails, it doesn't consume credits — so a bad run costs you nothing but time.
Settings that actually change your result
- Draft at 480p, finish at 1080p. Most of your iterations are about getting the prompt right; do those cheap, then render the keeper at full resolution.
- Use Fast mode to explore, standard to deliver. Fast is for "does this idea work at all." Switch to standard Seedance 2 once you know it does.
- Shorter clips read better. A tight 5-second shot usually beats a loose 12-second one — AI video drifts the longer it runs.
- One clear action per prompt. Stacking three camera moves and two subjects into one clip is the fastest way to get mush.
"Seedance 2 isn't working" — quick fixes
Most "not working" or "not available" complaints trace back to access, not the model:
- Can't sign up on the official app? That's usually the phone-number/region wall. Use a browser generator that signs in with email or Google instead.
- Generation failed? Re-run — failures don't cost credits here. If it repeats, simplify the prompt or drop the resolution.
- Output not matching the prompt? Cut it down to one subject and one action, and describe the camera move explicitly.
What does it cost?
There's a limited free tier on ByteDance's own apps, and pay-as-you-go credits if you need more than a clip or two a day. We broke the numbers down — free limits vs. real per-clip cost — in Is Seedance 2.0 free?. Short version: you can check current pricing here, and the credit cost is always shown before you generate.

"Seedance 2.1" hasn't officially launched as of mid-2026 — it's preview reporting, not a release. On this site the "Seedance 2.1" option currently generates with the released Seedance 2 model and switches over when 2.1 ships.
FAQ
How do I use Seedance 2.0 in the US?
Open a browser-based generator, sign in with email or Google, pick a mode, write a prompt, preview the credit cost, and generate. You don't need the Dreamina app or a Chinese phone number.
Do I need to download an app?
No. A web generator runs in the browser — no install, no API, no region setup.
What resolution and length can I generate?
480p, 720p, or 1080p, with clips from 4 to 15 seconds. Seedance 2 Fast covers 480p and 720p for quicker drafts.
Why isn't Seedance 2 working for me?
Most often it's the official app's sign-up wall (phone number / region), not the model. A web generator avoids that. If a specific generation fails, re-run it — failed generations don't cost credits.
What's the difference between Seedance 2 and Seedance 2 Fast?
Standard Seedance 2 favors quality; Fast trades some fidelity for speed and a lower credit cost. Draft in Fast, deliver in standard.
