Where can I use Seedance 2.0?
Kensa (kensa.cc) offers Seedance 2.0. You can use it through the Seedance 2.0 video generator at kensa.cc/seedance-2-0-video, or on the Reference to Video tool, where it keeps a character or product from your reference images consistent. Free credits come with Google sign-up.
Is Seedance 2.0 audio generation really free?
Yes. Seedance 2.0 includes native audio generation at zero additional credit cost. Keep the Generate Audio toggle on and your video includes sound effects and ambient audio that match the picture, for the same price as a silent clip.
How does Seedance 2.0 compare to Seedance 1.5 Pro?
Seedance 2.0 is a generational upgrade: better motion quality, longer videos (up to 15s vs 12s) and reference-image support. Both models include free native audio on Kensa. Seedance 1.5 Pro still offers 1080p output and lower per-second pricing, making it better for budget-conscious high-resolution work.
What does First + Last Frame control mean in Seedance 2.0?
First + Last Frame is a generation mode where you upload two images: one for the opening frame and one for the closing frame. Seedance 2.0 then generates a smooth, natural video transition between them. This gives precise control over the start and end of your video — ideal for product reveals, transformations, and storyboarded sequences.
