What Is Seedance 2?

Seedance 2.0 is ByteDance's next-gen AI video model — a unified Multimodal Diffusion Transformer that takes text, images, video, and audio in one pass and produces video with synchronized audio.

  • Realistic Human Generation
    Convincing anatomy, multi-person interaction, and emotive performance — hands, faces, and body mechanics hold up where earlier models failed.
  • Multimodal References
    Up to 9 images, 3 video clips, and 3 audio files in a single call. Carry subject, motion style, and voice forward together.
  • Native Audio + Video
    Music, ambience, dialogue, and Foley generated with frame-level awareness — dual-channel stereo and spatial audio in one pass.
  • Unrestricted Generation
    Bold, expressive, stylized human work that gets filtered out elsewhere generally comes back as a finished clip on VidCella.

FAQ

FAQs about Seedance 2

Common questions about Seedance 2 on VidCella

1

What is Seedance 2?

ByteDance's flagship AI video model, launched February 2026. A unified Multimodal Diffusion Transformer that accepts text, images, video, and audio references and generates video with native synchronized audio in one pass. Topped Artificial Analysis at Elo 1,269 (T2V) and 1,351 (I2V) at launch.

2

How realistic is the human generation?

Seedance 2 is the first ByteDance video model to handle realistic human anatomy, multi-person interaction, and emotive performance at production quality — SOTA on SeedVideoBench-2.0 multi-subject physical interaction.

3

What does "unrestricted" mean on VidCella?

Most hosted platforms wrap Seedance 2 in heavy moderation that strips away creative latitude the model itself supports. VidCella runs Seedance 2 with substantially looser filtering — bold, expressive, stylized work generally comes back as a finished clip. Handle real-person likeness, trademarks, and applicable law responsibly.

4

What resolutions, durations, and aspect ratios are supported?

Standard: 480p, 720p, or 1080p. Fast: 480p or 720p only (1080p is not exposed on the Fast variant by upstream). Both variants run 4-15 seconds with six aspect ratios: 16:9, 9:16, 4:3, 3:4, 21:9, 1:1.

5

How do multimodal references work?

Up to 9 reference images, 3 video clips (≤15s total), and 3 audio files in one generation — encoded into a shared representation space so subject, motion, environment, and voice can be carried forward together.

6

Seedance 2 vs Seedance 2 Fast?

Same feature set, but Fast caps at 720p while Standard goes up to 1080p. Fast trades some quality for lower cost (19-41 credits/s) versus Standard's 24-130 credits/s. Use Fast for iteration, Standard for the keeper.

7

How much does Seedance 2 cost on VidCella?

Per-second pricing — rate depends on resolution and whether you use a video reference (which lowers the rate). Standard: 24-130 credits/s (480p / 720p / 1080p). Fast: 19-41 credits/s (480p / 720p). No subscription.

Can I use Seedance 2 videos commercially?
