Seedance 2.0
ByteDance's next-gen model with native audio and multimodal references
Seedance 2.0 is ByteDance's next-generation AI video model, delivering native audio generation, multimodal reference support, and first/last frame control in a single platform. It represents a significant step up from Seedance 1.5 Pro — improved motion quality, richer audio fidelity, and support for multiple reference inputs to guide character and scene consistency. On Xarith, Seedance 2.0 is available on-demand alongside every other major video model, with no separate ByteDance account required.
Native audio with improved fidelity
Seedance 2.0 generates synchronized dialogue, ambient sound, and audio effects as part of the same generation pass as the video. Audio quality and synchronization accuracy are improved over Seedance 1.5 Pro, with more natural-sounding dialogue and better ambient sound integration. For social content and UGC-style ads that need native audio, this removes the post-production audio step entirely.
Multimodal reference support for consistency
Unlike Seedance 1.5 Pro, Seedance 2.0 supports multimodal reference inputs — providing character images, style references, or product visuals that the model uses to maintain visual consistency across the generated video. This is particularly useful for brand video content that needs to feature specific products or characters accurately.
First and last frame control
Define the exact opening and closing frame of your video using reference images. Seedance 2.0's first/last frame support makes it straightforward to create videos that start or end with a specific visual — useful for product reveals, branded transitions, and content that needs to connect seamlessly with other footage.
