FAQ
How does Seedance 2.0 compare to 1.5 Pro?
Seedance 2.0 offers significantly better visual quality, longer duration (up to 15s vs 12s), more aspect ratios, and multimodal input support. However, it only supports up to 720p (1.5 Pro supports 1080p) and costs more per generation.
Can I use real person photos for image-to-video?
No. Seedance 2.0 currently does not support real person photos as input for image-to-video generation. You can use illustrations, product images, landscapes, or other non-human subjects. For real person image-to-video, consider using Kling 3.0 instead.
What is Seedance 2.0 Fast?
Seedance 2.0 Fast is a faster, more affordable variant that produces slightly lower quality results. It's ideal for rapid iteration and prototyping.
