Seedance 2.0

What is Seedance 2.0?

Seedance 2.0 is a new generation of multimodal officially released by ByteHop in February 2026AI Video GenerationModeling. As the currentVideo GenerationIt is a benchmark product in the field of “director-level” control ability as the core, supporting four modal inputs: image, video, audio and text, and realizing the whole process of video creation from simple instructions to complex narratives. Its technological breakthroughs areEnd the uncertainty of traditional AI video generationThe user can accurately control character movement, camera language, and rhythmic atmosphere through natural language or reference material to generate high-quality, highly controllable multi-camera videos.

Key Features of Seedance 2.0

1. Multimodal inputs and references
   • Support for simultaneous uploads9 images, 3 videos, 3 audiosand natural language commands, the model can refer to the composition, movement, mirror, special effects, sound and other elements in the material to generate videos.
   • For example, if you upload a photo of a character, a dance video and a piece of music, you can generate a complete music video of the character dancing according to the movements of the reference video, with precise synchronization of lip-synchronization, dribbling and rhythm.
2. Native audio and video synchronization
   • Synchronized audio and video generation with support forReal-time mouth synchronization for more than 8 languages (including Chinese dialects)The ambient sound effects (e.g., rain, footsteps) and background music automatically match the scene's atmosphere.
   • For example, enter the cue “A man says ‘Welcome to today's program! with the audience cheering in the background’, the model will synchronize the corresponding lip-sync, sound effects and music.
3. Multi-camera narratives and coherence
   • A cue can be automatically split into multiple coherent shots, keeping theCharacter Consistency, Lighting Continuity, and Narrative FluencySupport for up to60 seconds.of complex scene generation.
   • For example, if you type “Detective checking out photos in an alley -> walking to a jazz bar -> ordering a drink at the bar”, the model will generate three shots with natural transitions.
4. Video Editing and Extension
   • Support for existing videosCharacter replacements, clip additions and deletions, pacing adjustmentsThe video can be extended seamlessly (e.g. from 15 seconds to 60 seconds), maintaining a natural flow of images and pacing.
5. Physical realism and motion stability
   • Deep understanding of gravity, momentum and other physical laws, generating actions that conform to real-world logic (e.g., skateboarding tricks, sports actions), and stable performance in complex sports scenes (e.g., multiplayer interactions, large-scale battle effects).

Core technology of Seedance 2.0

1. Unified Multimodal Audio/Video Co-Generation Architecture
   • Based on a single model to handle four modal inputs of image, video, audio and text, it avoids the error accumulation of traditional multi-model splicing and improves the generation efficiency and consistency.
2. Extreme Sparse Architecture
   • By optimizing the model structure, it improves the training and inference efficiency and reduces the consumption of computational resources while maintaining high quality output.
3. Generalization capabilities and combinatorial references
   • The model can learn the style, camera movement, rhythm and other elements of the reference material, and flexibly combine and apply them. For example, if you upload a movie-quality walking video, the model can reproduce its camera language into a new scene.
4. Audiovisual integration synergy
   • In multi-dimensional measurements (e.g., complex audio/video command compliance, professional camera language, audio/video expressiveness), Seedance 2.0 is an industry leader, supporting cinematic color, light and shadow, and ambience rendering.

Scenarios for Seedance 2.0

1. Film, Television and Advertising Production
   • Reduce production costs by quickly generating split-scene scripts, trailers, and special effects clips. For example, replicate commercial-grade editing styles with reference videos, or generate virtual actor performances.
2. Short videos and social media
   • Individual creators can generate high-quality short videos, such as music videos, short dramas, product demos, etc. with simple commands or images.
3. E-commerce & Marketing
   • Auto-generated product display video, support dynamic transportation mirror and background music matching, to enhance the user's desire to buy.
4. Games & Animation
   • Generate game over animations, character movement libraries, or synchronized animations based on audio (e.g., characters lip-synching).
5. Education and training
   • Produce instructional videos, historical scene reenactments, and virtual experiment demonstrations to enhance interactivity and immersion.

How to use Seedance 2.0?

1. Access platforms
   • Via the official ByteDance platformDreamina(at dreamina.capcut.com) or third-party APIs such as Atlas Cloud to use Seedance 2.0.
2. Select Creation Mode
   • Vincennes Video: Enter a descriptive cue (e.g., “A woman in a red dress walks through a cherry blossom garden as the camera slowly advances”) to generate a 5-10 second video.
   • Toussaint Video: Upload a reference image, add a description of the motion (e.g., “Headset rotates on desktop, lens wraps around 180 degrees”), and generate a motion video.
   • Omni-Reference Model: Mixed uploading of images, video, and audio with the@The syntax specifies the use of the material (e.g.@Picture 1 as the main character,@video1 reference lens running), generating complex videos.
3. Optimize Cue Words
   • Use structured formulas:Cues = Subject + Action + Scene + Camera + Style.
   • Example:A detective in a trench coat (@Photo 1) standing in an alleyway checking out the photo, close-up of his face, rain falling, camera following him from behind (@Video 1), panoramic view of neon city street at night, warm cinematic texture (@StyleRef).
4. Utilizing reverse cue words
   • Excluding unwanted elements (such asBlurring, low quality, facial distortion) to improve the quality of output.
5. Edit & Extend Video
   • Use the platform tools to replace characters, add footage, trim clips, or seamlessly extend the length of time with the Video Extension feature.
6. Adjusting output settings
   • Choose the resolution (up to 2K), duration (5-60 seconds), and make sure that the prompt contains keywords such as “high quality, sharp details”.
