What it does
Seedance 2.0 Text-to-Video, in practice.
Seedance 2.0 is a state-of-the-art multimodal generative AI model designed for synchronized video and audio content creation. Developed by ByteDance and integrated into the CapCut/Dreamina platform as of March 2026, this model family advances the field of generative multimedia by combining sophisticated diffusion transformer architectures with physics-informed world modeling for realistic motion and spatial consistency. Seedance 2.0’s significance lies in its Dual-Branch Diffusion Transformer (DB-DiT) architecture that jointly processes video and audio streams, enabling phoneme-level lip synchronization across multiple languages. Compared to previous iterations, it achieves substantially hig
- Dual-Branch Diffusion Transformer Architecture: Seedance 2.0 integrates separate yet synchronized diffusion branches for video and audio, enabling tight coupling between visual motion and sound generation. This architecture improves motion realism and audio-visual coherence beyond previous generative models.
- World Model with Physics Simulation: The model incorporates a physics-based world modeling approach that simulates realistic object motion and spatial consistency over time. This leads to naturalistic dynamics and stable scene composition across generated video sequences.
- Rich Multimodal Input Support: Seedance 2.0 accepts diverse input formats including text prompts, up to 9 images, and up to 3 video or audio clips of 15 seconds each. This flexibility allows nuanced content creation workflows combining static, dynamic, and auditory cues.
- Phoneme-Level Lip Synchronization: The native audio generation pipeline supports lip-sync at the phoneme granularity in 8+ languages, ensuring high fidelity mouth movements closely match generated speech or singing.
- High Usability and Efficiency: The model achieves an estimated 90% usable output rate compared to an industry average of approximately 20%, reducing post-processing overhead. Additionally, it delivers a 30% inference speed advantage over predecessor systems.
- API Variants for Different Use Cases: The Seedance 2.0 endpoint is geared toward high fidelity and cinematic visual effects suitable for final production, while the Seedance 2.0 Fast variant offers roughly 3 times faster generation and approximately 91% cost savings at $0.022 per second of output, ideal for rapid iteration and volume workflows.

resolution | Video resolution. "4k" is native UHD (3840×2160, 16:9) available on the full Seedance 2.0 models only (not Fast/Mini); 4K output is 10-bit, H.265/HEVC encoded and may not play in all browsers. | 480p 720p 720p-SR 1080p 1080p-SR 1440p-SR 4k |
ratio | Aspect ratio. 'adaptive' automatically selects based on prompt context. | 16:9 4:3 1:1 3:4 9:16 21:9 adaptive |
bitrate_mode | Output video bitrate mode. 'high' encodes at a higher bitrate for a crisper, larger file; 'standard' uses the normal bitrate. Does not affect token cost. | standard high |
generate_audio | Whether to generate synchronized audio (voice, sound effects, background music). | default True |
seed | Seed integer used to control the randomness of generated content. Value range: [-1, 2^32-1]. The default -1 means a random seed is used. The same seed with the same request produces similar results, but complete consistency is not guarantee | default -1 |
watermark | Whether to add a watermark. | default |
return_last_frame | Whether to return the last frame as a separate image. | default |
Sample prompt
The prompt behind the sample.
A cinematic view of the endless ocean at sunrise, golden sunlight spreading across the deep blue sea, powerful waves rising and crashing with white foam. The camera flies low above the water surface, water droplets and mist glowing in the light. Massive clouds stretch across the sky while seabirds glide through the wind. The ocean feels vast, powerful, and majestic, dramatic lighting, volumetric light rays, ultra detailed water simulation, epic cinematic atmosphere, 4K.
