Block the shot
Type a prompt, drop a first frame (or a first and last), or attach reference images, a clip, and audio. Spell out the camera move and the mood — Seedance 2 acts on that direction, not just the contents of the frame.
ByteDance Seedance 2 · the full tier, now with native 4K 
Seedance 2 AI Video Generator
ByteDance's top Seedance tier — native 4K, highest fidelity, the one you finish a shot on
Seedance 2 is the full, top-fidelity tier of ByteDance's Seedance family, and SupaImagine runs it in the browser. It's the only Seedance tier that renders all the way to native 4K — the one to reach for when a clip is the final delivery, not a rough cut. Generate from text, a frame, or video and reference media, hold motion and camera steady across four-to-fifteen-second takes, and get native synced sound on every clip, all saved to your library.
- The only Seedance tier with native 1080p and 4K
- Native synced audio on every clip
- Cinematic camera and motion you direct in the prompt
- Text, a frame, or references — all three inputs
- Every render kept in your private library
Run Seedance 2
Write a prompt, add a starting frame, or attach references, pick a resolution up to 4K, then run. Your result — rendered with synced audio — lands straight in the library.

The Seedance Tier You Finish On
Top of the family — native 4K, the highest quality grade, and full multimodal control.
Seedance 2 is ByteDance Seed's audio-video model — it generates picture and sound together, holds motion steady, and takes direction on camera and light. The full tier is where the family tops out: it's the only Seedance variant that renders native 1080p and 4K, at the highest quality grade, so a clip reads as finished delivery rather than a draft. That fidelity is a premium pass — it renders slower than the Fast and Mini tiers and costs more per clip — which is exactly the trade you make on a hero shot, an opener, or a take a client signs off on. When you're roughing out ideas or working at volume, Fast and Mini are the cheaper, quicker tiers; when the clip is the final one, this is the tier. All three share the same picker, so your prompt and frame carry across the switch.

How it works
Render a Seedance 2 Clip in Four Steps
2
Choose resolution up to 4K
Pick 480p, 720p, 1080p, or native 4K, an aspect ratio, and a length from four to fifteen seconds. The generator shows the exact credit cost before you run, so the 4K pass is a deliberate choice.
3
Render the take
Send it off. It moves through the queue while you set up the next shot, and if a run fails its credits come straight back to your balance.
4
Keep and reuse
Every clip saves to your private library. Re-run with a tweaked prompt, or rough the next idea on a Fast or Mini tier and bring the keeper back here for the final 4K render.
What the Full Seedance 2 Gives You
The only Seedance tier that reaches 4K
Seedance 2 renders native 1080p and 4K; the Fast and Mini tiers stop at 720p. 4K is the resolution you reach for when the clip is the deliverable rather than a draft — a hero shot, a title opener, a frame that holds up on a big screen. Same prompt and frame as the lighter tiers, far more detail in the picture.
Sound that ships with the final cut
Because Seedance 2 lays down audio in the same pass as the picture, the clip you export is already scored — ambience and foley locked to the motion, no separate audio session before delivery. On a finishing tier that's the gap between a render and a deliverable, and there's no toggle to forget.
Camera direction that holds at full resolution
Write the move into the prompt — a slow push-in, a locked-off lens, a deliberate rack focus — and the top tier carries it through the take instead of letting detail smear as the resolution climbs. Directing the camera, not just listing what's in frame, is what makes a 4K clip read as photographed.
Multimodal references for consistency
Feed up to nine reference images, three clips, and three audio files so a character, a look, or a sound carries from one shot to the next — and pick any duration from four to fifteen seconds rather than a fixed clip length. It's the control you want when a final sequence has to feel like one piece.
Mini vs Fast vs Seedance 2
Mini, Fast, or the Full Seedance 2 — When to Go Top-Tier
The full tier sits at the top: native 4K and the highest quality grade, at a slower premium pass. Mini and Fast share the 720p ceiling for drafts and near-final work.
| Seedance 2 Mini Cheapest · for drafts | Seedance 2 Fast Balanced · near-final | ||
|---|---|---|---|
| Best for | High-volume drafts, storyboards, tests | Near-final clips and client-ready work | Hero shots and final 4K delivery |
| Quality grade | Good | Higher | Highest |
| Max resolution | 720p | 720p | 1080p / 4K |
| Relative cost | Lowest | Low–mid | Highest |
| Speed | Fast | Fast | Slower (premium pass) |
| Native synced audio | Yes | Yes | Yes |
Three ways in
Drive Seedance 2 With Text, a Frame, or References
The same three input modes across the family — choose the one that matches the material you're starting from.
Text-to-video — direct a take from a sentence
Describe the scene, the action, and the camera move; Seedance 2 builds the whole take from words and renders it up to 4K. The starting point that needs no footage at all.
Image-to-video — bring a still up to 4K motion
Hand it a first frame, or a first and last frame to move between, and a single image becomes a finished clip — a product render, a piece of key art, a hero still — at full resolution.
Reference-to-video — carry a look across a sequence
Attach up to nine images, three clips, and three audio files so a character, palette, or sound stays consistent shot to shot; a source clip bills lower than generating cold.
Where it fits
Where the Full Seedance 2 Earns the Premium
The top tier suits the work that ships — where 4K and finished motion matter more than turnaround.
Brand & hero films
The single hero clip a campaign is built around, rendered at 4K with directed camera moves and synced sound — the take everything else supports.
Film & trailer beats
Short narrative shots and trailer moments where the camera language carries the cut, and a 4K master holds up projected or on a large screen.
Premium product launches
Hero product motion for a launch page or storefront — animate a still into a 4K demo where the surface detail and finish are the whole point.
Music videos & visualizers
Performance and atmosphere clips that come back with their own generated audio, cut at full resolution for release rather than a rough pass.
Final agency delivery
The version a client actually signs off on — top-grade fidelity, optional 4K master, and commercial-use rights on a paid plan.
The Full Seedance 2, Answered
What is Seedance 2?
Seedance 2 is the full, top-fidelity tier of ByteDance Seed's Seedance 2 — an audio-video model that generates picture and synced sound together. It's the only tier in the family that renders native 1080p and 4K, holds motion and camera direction steady, and takes text, a starting frame, or video and reference media as input. On SupaImagine you run it in the browser next to the Fast and Mini tiers and other top models like Veo 3, all in one workspace.
When should I use the full Seedance 2 instead of Fast or Mini?
Reach for the full tier when the clip is the final delivery. It's the only Seedance tier that renders 1080p and 4K and it sits at the highest quality grade, so it's the right call for hero shots, openers, and anything a client signs off on. Fast and Mini share a 720p ceiling and a quicker, cheaper turnaround — better for drafts, tests, and high-volume work. A common flow is to rough a shot out on Mini or Fast, then render the keeper here; your prompt and frame carry across the switch.
Seedance 2 vs Veo 3 — how do they differ?
They're both flagship video models on SupaImagine, from different houses, and they're strong at different things. Seedance 2 gives you flexible four-to-fifteen-second clips plus video-to-video and multimodal references, so you can carry a character, look, or sound across shots. Veo 3 works in fixed-length clips and reaches up to 4K as well, with its own visual character. Rather than pick on paper, run the same prompt through both in one workspace and keep the result you prefer.
Does Seedance 2 render 4K, and how long can a clip be?
Yes — the full Seedance 2 renders 480p, 720p, 1080p, and native 4K, and it's the only Seedance tier that goes past 720p. Clips run from four to fifteen seconds, in aspect ratios from 1:1 and 16:9 to 9:16 and 21:9. The generator shows the exact credit cost for each combination before you run, so a 4K master is always a deliberate choice.
Do Seedance 2 clips come with sound?
Yes — Seedance 2 generates native synced audio together with the picture, so every clip comes back with sound built in, the same across the whole family. There's no separate scoring step and no toggle to manage; the audio arrives with the render.
What does a Seedance 2 clip cost in credits?
Video is billed by the second and scales with resolution, so a longer or higher-resolution clip costs more — and 4K runs at roughly twice the per-second rate of 1080p. The generator shows the exact credit cost before you run. As the top tier, Seedance 2 costs more per clip than Fast or Mini. A new account gets a few free credits to explore the workspace, but you'll add a plan or credit pack before rendering clips; current packages are on the pricing page.
Can I use Seedance 2 clips commercially?
On a paid plan, yes — clips you render there are cleared for commercial use, from brand films to client delivery. The free starter credits are for trying the workspace and don't carry commercial rights. The legal page has the exact terms.
