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.
