Which one to pick
Seedance 2.0 Mini
Bulk drafting and previews. The cheapest video generation in the catalog, at 480p or 720p.
Seedance 2.0 Fast
Faster turnaround than 2.0 at a lower price, with the same reference inputs, capped at 720p.
Seedance 1.5 Pro
The previous generation, still useful when you want audio toggled per request and pricing quoted per duration/resolution/audio combination.
Seedance 2.0
The generation workhorse: 4-15 second clips, multimodal references, and 4K output when you need it.
Seedance 2.5
The longest takes we offer — up to 30 seconds — plus MP4/MOV choice and an extend mode for continuing an existing clip.
Strengths
- Duration is a parameter, not a fixed length, and 2.5 reaches 30 seconds.
- Seven aspect ratios including 21:9 and 4:3, plus an adaptive option on the 2.x tiers.
- References go beyond a still frame — image, video and audio inputs are accepted on 2.x.
- Price is quoted per resolution and duration, so cheap drafts are genuinely cheap.
Limitations
- Only 2.0 reaches 4K; the Fast and Mini tiers stop at 720p.
- The pricing matrix is the most complex in the catalog — cost depends on resolution, duration and, on 1.5 Pro, whether audio is generated.
- Tiers are not drop-in equivalents: 1.5 Pro exposes an audio switch and fixed duration steps that the 2.x tiers handle differently.
