Its key differentiator is free native audio generation — including sound effects, ambient audio, and multi-language lip-sync dialogue — at no extra cost.
Where can I use Seedance 2.0?
Kensa (kensa.cc) is among the first platforms worldwide to offer Seedance 2.0 access. You can use it through the Seedance 2.0 video generator at kensa.cc/seedance-2-0-video, or via the text-to-video and image-to-video tools where Seedance 2.0 is available as a model option. Free credits are included on signup.
Is Seedance 2.0 audio generation really free?
Yes. Unlike Kling 3 (which charges approximately 50% extra for AI Sound Sync), Seedance 2.0 includes native audio generation at zero additional credit cost. Enable the Generate Audio toggle and your video includes synchronized sound effects, ambient audio, and lip-sync dialogue within the same price.
How does Seedance 2.0 compare to Seedance 1.5 Pro?
Seedance 2.0 is a generational upgrade: dramatically better motion quality, free native audio (1.5 charged extra), multi-language lip-sync, longer videos (up to 15s vs 12s), and support for video and audio references. 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.
