Frequently Asked Questions

What is Seedance 2.0?
Seedance 2.0 is ByteDance's AI video generation model, known for high-quality video output with realistic motion. It's the model underlying some CapCut AI video features and is available to developers via APIs like fal.ai. ByteDance developed it as a direct competitor to Runway and Kling.
Is Seedance better than Runway?
Seedance 2.0 produces video quality competitive with Runway Gen-4.5 at potentially lower API costs. However, Runway offers a complete production platform with multiple models, editing tools, and professional workflows that Seedance alone doesn't match. For raw generation quality, they're comparable; for production use, Runway has more tools.
How do I access Seedance 2.0?
Seedance 2.0 is primarily accessible through developer APIs (fal.ai, Replicate) or indirectly through CapCut's AI video features. There's no dedicated Seedance consumer product — it's an underlying model accessed through other platforms.
Is Runway the best AI video tool?
Runway is considered the leading professional AI video platform with Gen-4.5 ranking highly on quality benchmarks. Its multi-model subscription (including Veo 3.1, Kling, Seedance) makes it the most comprehensive option. For pure generation quality comparisons, Veo 3 and Kling 3.0 are competitive alternatives.
