What is the difference between Seedance 2.0 Pro and Seedance 2.0 Fast?

Seedance 2.0 Pro delivers the highest quality output at 30 credits per second — ideal for final marketing videos, social media posts, and commercial content where cinematic motion and visual detail matter most. Seedance 2.0 Fast generates videos at 25 credits per second with faster turnaround, making it best for draft exploration, concept testing, and rapid iteration before committing to a final render. Both support text-to-video and image-to-video in all six aspect ratios.
