Seedance 2: finish-tier clips with 1080p and native 4K
Highest Seedance fidelity on SupaImagine — always-on audio, multimodal inputs, 4–15 seconds.
Full Seedance 2 is the family top rung: 480p through 4K, always-on synced audio, and text, frame, or reference inputs. Per-second pricing rises with resolution — 4K costs roughly double 1080p on this tier. Use Fast or Mini while you hunt ideas; open full when the shot must ship.

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.
How it works
Render a Seedance 2 Clip in Four Steps
1
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.
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.
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.
Mini vs Fast vs Seedance 2
Mini, Fast, or the Full Seedance 2 — When to Go Top-Tier

Seedance 2 questions before you generate
When should I use full Seedance 2 instead of Fast or Mini?
Reach for full Seedance 2 when the clip is final delivery. It is the only Seedance tier with 1080p and native 4K, and it sits at the highest per-second rates. Keep Fast or Mini for volume drafts.
Does Seedance 2 render 4K, and how long can a clip be?
Yes — full Seedance 2 renders 480p, 720p, 1080p, and native 4K. Clips run from four to fifteen seconds. Fast and Mini stop at 720p.
Do Seedance 2 clips come with sound?
Yes. Audio is always-on for Seedance 2 on SupaImagine — not an optional mute switch. Picture and synced sound return together.
How do Seedance 2 credits scale?
Video bills per second and rises with resolution. Rough guide for text/image paths: 480p 25/s, 720p 45/s, 1080p 105/s, 4K 210/s. Reference-video paths can bill lower when a video ref is present. Check the generator estimate before you run.
What inputs does full Seedance 2 accept?
Text-to-video, image/frame-to-video, and reference paths including video references where exposed. Use refs when continuity across shots matters more than a pure text draft.
What are the default length and resolution?
Defaults center on a short mid-resolution take (commonly around 5s at 720p in the catalog). Change duration and resolution before generate so credits match the delivery you want.
Where do finished clips go?
Renders land in your private SupaImagine library so you can review, download, or re-run without losing the take.
Can I use Seedance 2 clips commercially?
On a paid plan, yes — subject to SupaImagine Terms and any third-party rights in your prompts or references. Evaluation balance alone is not a commercial license.
