Key Features of Seedance 2.0 API
ByteDance's director-level multimodal video model with unified audio-video generation, multi-shot storytelling, and cinematic motion control.
01
Unified Audio-Video Joint Generation
Seedance 2.0 uses a Dual-Branch Diffusion Transformer architecture to generate video and audio together in a single pass. Sound effects, dialogue, music, and ambient atmosphere are produced natively alongside the visuals, eliminating the need for separate sound design or post-production audio alignment.
- Native audio generated with video
- Dialogue, SFX, music, and ambient tracks
- Dual-Branch Diffusion Transformer
02
Multimodal Inputs: Text, Image, Video, and Audio
Seedance 2.0 accepts text prompts together with up to 9 images, 3 video clips (≤15s total), and 3 audio files (≤15s total) in a single request—up to 12 combined reference assets. This flexible input system lets creators blend visual references, motion cues, and audio signals to express complex creative intent in one generation.
- Up to 12 combined reference assets
- Mix text, image, video, and audio
- Structured reference tagging
03
Native Multi-Shot Storytelling
Generate cohesive multi-shot sequences from a single prompt. Seedance 2.0 maintains character consistency, visual style, and narrative continuity across camera cuts and transitions, making it ideal for short films, ads, and social content without manual stitching between clips.
- Multiple shots from one prompt
- Character and style consistency
- Seamless cuts and transitions
04
Native Dialogue and Lip-Sync in 8+ Languages
Seedance 2.0 produces clear, timing-accurate dialogue with lip-sync across more than eight languages, including English, Chinese, Japanese, and Korean. Speech, intonation, and facial motion are coupled at generation time, so localized content looks and sounds natural without post-processing alignment.
- Lip-sync across 8+ languages
- Clear, accurate dialogue timing
- Natural intonation and mouth motion
05
Director-Level Cinematic Control
Full creative influence over performance, lighting, shadows, camera movements, and physics. Seedance 2.0 understands directives like tracking, orbiting, and panning, delivers realistic motion stability, and aligns output with industry cinematic standards—making it excellent for action, dance, and fight sequences.
- Camera motion: tracking, orbit, pan
- Realistic physics and motion stability
- Cinematic lighting and shadow control
06
Video Extension, Style Transfer, and Enhancement
Beyond fresh generation, Seedance 2.0 supports conversational refinement, video extension, style transfer, and enhancement workflows. Use it to push existing footage further—extend scenes, restyle looks, or refine outputs iteratively within the same API surface.
- Extend existing video clips
- Style transfer and restyling
- Iterative refinement workflows
Who Can Benefit from Seedance 2.0 API?

Film and Pre-Visualization
Generate multi-shot pre-vis sequences with synchronized dialogue and ambient audio from a single prompt. Directors can test pacing, blocking, and camera work before committing to physical production.
02
Multilingual Content Localization
Adapt a single creative brief into regionally authentic video variants with native lip-sync across English, Chinese, Japanese, Korean, and more. Replace manual dubbing with model-driven localization.
03
Advertising and Marketing
Create cinematic ad concepts by combining product images, brand audio, reference footage, and copy in one request. Ideal for rapid iteration on hooks, reels, and social-first video campaigns.
04
Gaming and Interactive Media
Produce cutscenes, action sequences, and in-game video assets with consistent characters and immersive native soundtracks. Feed character art and audio cues to drive coherent narrative shots.
05
Education and Training
Build instructional video courses with consistent presenters and multilingual narration. Multi-shot storytelling keeps lessons visually engaging while native audio removes separate voiceover work.
06
Music Videos and Cinematic B-Roll
Leverage audio references to drive rhythm-synced visuals, or generate cinematic b-roll with strong motion stability. Seedance 2.0 excels at dance, action, and detailed gesture sequences.
