What Creators Say
Join thousands of creators making amazing content with Seedance 2.0.
Alex Chen
Film Director
The lip-sync technology is incredible. I've tried every AI video tool, and Seedance 2.0 is the first one that produces believable dialogue scenes. It's changed how I approach pre-visualization.
Maria Rodriguez
Content Creator
I create content in Spanish and English. Seedance 2.0's multi-language support is seamless - the lip sync works perfectly in both languages. My audience engagement has doubled.
Yuki Tanaka
Animation Studio Lead
The multi-shot capability is a game-changer. We can now generate complex scene sequences from a single prompt. It's like having a virtual cinematographer on the team.
James Wilson
Marketing Director
We've cut our video production time by 80%. The native audio generation means no more syncing issues or hiring voice actors for every language variant.
Sophie Laurent
Indie Game Developer
For game cinematics, Seedance 2.0 is unbeatable. The 2K quality and synchronized audio make our trailers look like AAA productions at a fraction of the cost.
Kim Min-jun
K-Drama Content Creator
Finally, an AI that understands Korean lip-sync! The phoneme-level accuracy is remarkable. My Korean content has never looked more authentic.
Frequently Asked Questions

What makes Seedance 2.0 different from other AI video generators?
Seedance 2.0 is the first AI video model with native audio-video synchronization. Unlike tools that generate video first and add audio later, Seedance 2.0 uses a Dual-Branch Diffusion Transformer to create perfectly synchronized audio and video simultaneously. This results in natural lip-sync, properly timed sound effects, and coherent audio-visual narratives.
Which languages are supported for lip synchronization?
Seedance 2.0 supports phoneme-level lip synchronization in 8+ languages: English, Chinese (Mandarin), Korean, Japanese, Spanish, French, German, and Portuguese. More languages are being added regularly. Each language has been specifically trained for accurate mouth movements and natural speech patterns.
What resolution and quality can I expect?
Seedance 2.0 generates videos in up to 2K resolution (2560x1440) with cinema-quality visual effects. The Pro plan will soon support 4K output. All videos feature smooth 30fps playback with high bitrate encoding suitable for professional distribution.
How does multi-shot narrative generation work?
With multi-shot generation, you can describe a complete scene sequence in a single prompt, and Seedance 2.0 will generate multiple coherent shots with consistent characters, settings, and story flow. For example, you can describe a conversation with reaction shots, and the AI will create a properly edited sequence.
Can I use generated videos for commercial purposes?
Yes! All paid plans (Basic, Plus, Pro) include full commercial rights to generated content. Free plan videos include a watermark and are for personal/non-commercial use only. We recommend reviewing our Terms of Service for specific usage guidelines.
How does Seedance 2.0 compare to Sora, Runway, and Veo 3?
Seedance 2.0 ranks #1 on the Artificial Analysis benchmark, outperforming Sora, Runway Gen-3, Veo 3, and Kling in overall video quality. Key advantages include native audio-video sync (no post-processing needed), superior lip-sync accuracy, multi-shot storytelling, and 30% faster generation speed. See our detailed comparison page for benchmarks.
What's the Dual-Branch Diffusion Transformer architecture?
The Dual-Branch DiT is Seedance 2.0's core innovation. It uses two parallel transformer branches - one for video generation and one for audio - that share information at each denoising step. This allows the model to generate perfectly synchronized audio and video rather than treating them as separate outputs.
Is there an API available for developers?
Yes, API access is available starting with the Plus plan. The Seedance 2.0 API allows you to integrate video generation into your applications, with support for text-to-video, image-to-video, and video-to-video transformations. Full API documentation is available at docs.seedance2.site.
