What is Seedance?
Seedance is an AI video generation model developed by the ByteDance Dreamina platform. It is an AI model that enables creative professionals to generate cinematic, realistic short videos and animation clips. The ByteDance video AI runs on a dual-branch diffusion transformer architecture and also allows 4 inputs, which are text, images, videos, and audio files, to create an output. Seedance 2.0 / 1.5 can generate sound effects and background music matching the timeline of the visuals. It is a dance choreography AI with an @Mention reference system for attaching videos, images, and audio files. The maximum number of inputs it allows is 3 audio files, 3 videos, and 9 images.
With the ByteDance video AI, you won’t need to work with text prompts alone; you can combine text prompts, audio, and video for precise outputs. The 4-modality input video AI will process all these inputs to deliver what you want accurately. The AI model offers director-level control, allowing you to specify camera movement, lighting, shadows, and performance throughout the clip. You also have control over the output to edit unwanted visuals, replace specific actions, and remove characters. Everything is ultra-realistic, from the physics and characters to the visual sequences and the details in each scene. It contains everything you need for professional content production in a single pass.
One of the best things about using this model is that you can access it directly on our platform in a browser, with no setup required. Creators can explore all the input modes to generate videos with synchronized audio.
What Makes Seedance Different
Mention Reference System
The 4-modality input video AI uses a @Mention reference system, allowing creators to upload multiple files to ensure high-quality output. It supports up to 9 images, 3 existing videos, and 3 audio files. Additionally, you can instruct the AI on how to use these assets by typing @ followed by the asset name.
Native Stereo Audio Generation
Seedance is an advanced multimodal AI video model that generates both video and audio simultaneously in a single workflow. It can add context-aware background music, environmental sound effects, and lip-syncing in more than 8 languages. You do not need an additional tool to do this, as the audio and video are generated within a single workflow.
Synchronized Dance Choreography
Creators can upload a reference audio file and the dance choreography AI will generate a matching motion for it. It excels in creating dance sync and complex choreography. It can generate rhythmic body movement, dance moves, and gestures to match the video reference. Also, thanks to being a character consistency video AI, it can maintain this motion across many scenes in your outputs.
Benchmark-Proven Quality
Seedance 2.0 delivers outstanding cinematic realism, consistently outperforming other AI video models. It has been celebrated for its dynamic motion, character consistency, and prompt adherence. In addition, the SeedVideoBench benchmark has also proven it to be an exceptional AI video model.
Key Features

Native Stereo Audio
Seedance 2.0 is an AI video model that can generate high-quality stereo audio and video within a single workflow. Unlike the previous process of generating a silent clip and adding audio later with a separate tool, the AI model generates both visuals and audio simultaneously.
2K Native Resolution
Seedance AI supports up to 2K native resolution video. This quality is an upgrade from the 1080p in the previous version. In addition, it can support various aspect ratios like 1:1, 4:3, 9:16, 16:9, and 21:9.
Multi-Shot Storytelling
Seedance AI video is a multi-shot AI video tool that lets you create a full, cinematic video sequence with camera angles, scene progression, and consistent characters. You can use this creative control to create short narratives and episodic content.
Realistic Physics Engine
Seedance 2.0 has a physics engine that supports character motion, collisions, fluid dynamics, and fabric simulation. These features remove the floating feel of earlier AI models by offering a believable physics model that adheres to real-world laws.
4–15 Second Clips
Seedance video generator can help create short videos and animation clips ranging from 4–15 seconds, supporting resolutions up to 1080p and 2K. This length is an upgrade from the 4–12 seconds in the previous version.
How It Works
Three steps to your video
Write Your Prompt
State a description of the scene, motion, camera direction, and mood within a video generation prompt of 60–100 words. For easier prompting, you can follow the 6-step prompt formula: Subject, Action, Setting, Camera, Style, and Audio.
Add References
Using the @Mention system, you can attach audio, images, and videos as creative references. You can use these as a basis for generating a character, motion, sound, and style.
Generate and Export
Seedance video generator handles multimodal input to generate video and high-fidelity audio simultaneously. Additionally, users can preview, regenerate, adjust references, and finally export in 2K resolution.
Audio Generation
Seedance 2.0 does not operate a bolt-on system in which audio is added to a silent clip later; it generates both simultaneously in a single pipeline.
Image-to-Video & Video-to-Video
Multiple input modes with @Mention reference integration
The <span class="highlight">@Mention</span> Reference System
The @Mention reference system is one of the most impressive features of Seedance 2.0. It is a feature unique to the AI model, as others only allow text prompts or image references.
How It Works
Using the AI model, you can attach 12 files, a total reference input to generate coherent outputs. This means you can combine 9 images and 3 video inputs when creating an output.
Users can attach up to 9 images to define the character's appearance and clothing.
Attaching 3 videos ensures you can define the camera path, action sequence, and motion.
With the audio-input video generation feature, creators can upload 3 audio files to determine background music, dialogue, and environmental sound in a visual output.
The model combines all attached references together while processing their audio references, character identities, and motion patterns into a single and coherent output.
Why It's Powerful
Text prompts can mean so many things. For example, “A fighting man” could mean various things. But attaching a character’s image or video to depict motion, and audio for sound effects, will ensure the AI model delivers accurate output.
The Competitive Edge
No other AI video model offers support for all 4 input modalities with the @mention system. Most of them work with text, images, or videos only.
Practical Applications
- Music videos: A combination of the artist's image, dance reference, and soundtrack produces a beat-matched music video.
- Brand content: Combining product images, motion visuals for style reference, and branded audio will generate a high-quality on-brand video.
- Film pre-vis: A mix of storyboard frames, camera-path references, and dialogue audio will help create pre-visualization.
