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

There is no separate 'Pro' version — the full-quality model is simply called Seedance 2.0. Seedance 2.0 delivers the highest quality output from 45 credits per second (480p), 100 at 720p, 220 at 1080p and 500 at 4K — 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 from 30 credits per second (63 at 720p, its maximum) 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, from 4 to 15 seconds. See Seedance 2.0 Fast.
