Seedance 2.0 is ByteDance’s current flagship video model, and the headline is scale: it renders at up to 4K resolution and stretches a single generation to 15 seconds. Creators reach for it when a shot needs both length and pixel density — think hero footage for landing pages or ultrawide 21:9 banners that would look soft coming from lower-resolution models.
On Flux 3 AI the family ships in three tiers. The standard Seedance 2.0 unlocks the full 4K ceiling, while Seedance 2.0 Fast and Seedance 2.0 Mini cap out at 1080p and trade fidelity for quicker, cheaper takes. Every tier accepts a text prompt or a starting image, takes up to nine reference images to lock down a subject, and offers an optional audio-generation toggle when you want sound included.
Duration options span 4, 5, 8, 10, and 15 seconds across six aspect ratios from square 1:1 to cinematic 21:9. A practical routine: rough out the idea on Mini, confirm framing on Fast, then commit credits to a 4K standard render — the prompt and references carry over untouched.

What makes Seedance 2.0 stand out
4K resolution ceiling
The standard Seedance 2.0 tier renders 480p through 4K, giving you delivery-grade footage without an upscaling pass.
Nine reference images
Feed up to nine references so characters, products, or environments stay recognizable from take to take.
15-second generations
Single clips run 4 to 15 seconds — nearly double what most flagship video models produce in one pass.
Optional audio toggle
Flip on audio generation when a clip needs sound; leave it off for silent renders that finish cheaper.
Three-tier lineup
Standard for 4K finals, Fast for quick 1080p turnarounds, Mini for high-volume drafting on a budget.
Ultrawide framing
Six aspect ratios including 21:9 cover cinema crops, web heroes, and vertical feeds from one model.

Which Seedance 2.0 version should you use?
Every version below is selectable in the Create studio on the same credits.
Seedance 2.0
The full-quality flagship tier and the only one that renders 4K. It shares the family specs — 4 to 15 second clips, six aspect ratios from 1:1 to 21:9, up to nine reference images, and the audio toggle — but adds the highest fidelity, so save it for final deliverables.
Seedance 2.0 Fast
The speed-oriented middle tier. Output tops out at 1080p instead of 4K, but the durations, all six aspect ratios, nine-image reference support, and the optional audio toggle are identical to the standard model. Choose it to confirm framing and motion quickly before committing credits to a 4K pass.
Seedance 2.0 Mini
The budget tier for volume work. Like Fast it caps at 1080p while keeping the 4-to-15-second durations, six ratios, references, and audio option, but it costs the least of the three. Ideal for brainstorming variations, classroom projects, or bulk social drafts where a low price beats maximum fidelity.
Seedance 2.0 prompt examples
Copy one as a starting point, or send it straight to the Create studio.
“A 21:9 ultrawide drone glide over a neon-lit coastal city at dusk, waves crashing against the seawall, camera slowly descending toward a lone cyclist crossing the bridge, teal-and-orange grade.”
Exercises the ultrawide frame with a long sustained camera move.
“Slow dolly-in on a perfume bottle rotating on wet black marble, mist curling around the glass, studio rim lighting, macro detail on the droplets, luxurious and quiet.”
Shows off 4K detail on product surfaces and fluid mist.
“A red-jacketed explorer trudges through a snowstorm toward a glowing ice cave, handheld tracking shot from behind, wind whipping loose snow, ambient blizzard sound, cold blue tones.”
Pairs the audio toggle with weather physics and character motion.

Seedance 2.0 questions, answered
What is Seedance 2.0?
Seedance 2.0 is ByteDance’s flagship AI video model, generating clips up to 15 seconds long at resolutions up to 4K from text or image prompts. On Flux 3 AI it runs in the cloud, so you can generate from any browser without installing anything.
Can Seedance 2.0 really output 4K video?
Yes — the standard Seedance 2.0 tier supports 480p, 720p, 1080p, and 4K output. The Fast and Mini tiers top out at 1080p, which keeps their renders quicker and less expensive for drafting work.
How many reference images does Seedance 2.0 accept?
Up to nine per generation, on every tier. That is enough to pin down a character from several angles plus a product and a location, which makes Seedance 2.0 one of the strongest models for consistent multi-shot storytelling.
Does Seedance 2.0 generate audio?
Audio is optional rather than automatic: switch on the generate-audio toggle in the Create studio and the clip arrives with sound. Leaving it off produces a silent render, which is the cheaper option when you plan to score the video yourself.
What is the difference between Seedance 2.0, Fast, and Mini?
All three share the same durations, aspect ratios, reference support, and audio toggle. The standard tier adds 4K output and the highest fidelity; Fast returns 1080p results quicker; Mini is the budget pick for exploring ideas in volume.
How long can a Seedance 2.0 clip be?
You can choose 4, 5, 8, 10, or 15 seconds per generation. The 15-second maximum is unusually long for a single pass and often removes the need to stitch multiple clips together.
Seedance 2.0 vs Kling 3 — which should I pick?
Pick Seedance 2.0 when resolution, clip length, or multi-reference consistency matter most. Kling 3 is a strong alternative for motion realism. Since both run on Flux 3 AI with the same credits, testing one prompt on each is the fastest way to decide.
Is Seedance 2.0 free to try?
Signing up for Flux 3 AI grants free credits that work on Seedance 2.0 and every other enabled model. Once those are spent, plans on the pricing page cover continued use, and all downloads remain watermark-free.
What aspect ratios does Seedance 2.0 support?
Six ratios are available on every tier: 1:1 square, 4:3, 3:4, 16:9 widescreen, 9:16 vertical, and 21:9 ultrawide. That means the same prompt can be reframed for cinema-style banners, desktop players, and phone feeds without leaving the model.
Can I use Seedance 2.0 through an API?
Yes — Flux 3 AI offers API access for developers, so Seedance 2.0 generations can be triggered from your own app or pipeline as well as from the browser studio. Details are outlined in the API section on the homepage.
