Overview
What is Seedance 2.0?
Seedance 2.0 uses a unified multimodal audio-video architecture that supports text, image, audio, and video inputs. ByteDance says the model can use mixed reference materials for composition, motion, camera movement, visual effects, and sound, then generate up to 15-second multi-shot audio-video output with two-channel audio. The official model page highlights motion stability, audiovisual generation, and director-level control over performance, lighting, shadow, and camera movement. For public international access, Runway currently offers Seedance 2.0 as a third-party model in its web creation workflow.

Compare first
Who should compare alternatives first?
- Compare alternatives if you need a free Seedance 2.0 workflow: Runway documentation says the model requires Standard or higher, even though a Runway account includes one-time free credits for other supported usage.
- Compare total output cost by model variant, duration, and resolution: Runway lists Seedance 2.0 Pro 1080p at 160 credits per 4 seconds and Seedance 2.0 Fast at 116 credits per 4 seconds.
- Plan for short sequences: the current Runway guide lists 5-15 second duration, and longer stories require multiple clips and an editing workflow.
- Review third-party content policies before using reference media; Runway documents that model-specific blocks are managed by the provider.

Recommendation
Should you use Seedance 2.0?
Shortlist Seedance 2.0 when your creative brief depends on combining several reference types, directing multi-shot action or camera intent, and generating sound with the video. Use the Runway pricing table to budget real output cost before committing, and compare alternatives if free access, longer clips, predictable flat-rate usage, or a different provider workflow matters more.
