Seedance 2.0 Model Reference

Overview

Seedance 2.0 is ByteDance's flagship multi-modal AI video generation model, released in February 2026. Built on a unified multimodal audio-video joint generation architecture, it enables creators to produce cinematic, high-fidelity videos by combining text prompts with up to 12 reference assets (images, videos, and audio). Unlike traditional text-to-video tools, Seedance 2.0 offers unprecedented control through natural language references, @-tagging for precise asset guidance, and seamless integration of motion, camera work, lighting, and audio.

Key Capabilities

• Multi-Modal Inputs: Supports text + up to 9 images (PNG, JPG, JPEG, WebP), 3 videos (MP4, MOV, total duration ≤15s), and 3 audio files (MP3, WAV, total duration ≤15s). Maximum 12 files combined.
• Output Specifications: Videos 4–15 seconds long at 480p, 720p, or 1080p resolution. Supported aspect ratios: 16:9, 9:16, 1:1, 4:3, 3:4, 21:9.
• Advanced Features:
  • Director-level control over performance, lighting, shadows, camera movements, and choreography.
  • Native audio-video joint generation with synchronized sound effects, background music, dialogue, and lip-sync.
  • Exceptional motion stability, realistic physics, and consistent characters/scenes across multi-shot narratives.
  • Video extension, editing, and merging while preserving style and continuity.
  • Frame-level precision using natural language and @-tagging (e.g., @Image1 as character, @Video1 for camera motion, @Audio1 for beat sync).

Strengths

• Unmatched Controllability: Reference specific elements from uploads (motion, style, sound) without complex prompting.
• Cinematic Quality: Produces industry-standard output with realistic body dynamics, contact physics, and multi-camera storytelling.
• Consistency & Realism: Locks faces, clothing, text, and visual style across shots; excels in action sequences, VFX, and immersive experiences.
• Efficiency: Fast generation (4–15 seconds per clip); supports iteration via upload-and-extend workflows.
• Creative Flexibility: Ideal for ads, short films, music videos, social content, pre-vis, and more.

Limitations

• Input Constraints: Strict limits on number and total duration of reference files; audio inputs require at least one visual asset.
• Video Length: Maximum 15 seconds per generation (extensions possible but must match added duration for seamlessness).
• No Standalone Audio: Cannot generate video from audio + text alone.
• Resolution & Speed Trade-offs: Higher resolutions (1080p) consume more compute; Fast mode (where available on platforms) prioritizes speed over final polish.
• Prompt Sensitivity: Overly vague prompts without @-tagging may reduce precision; best results come from structured, reference-heavy inputs.

How to Write Effective Prompts

Seedance 2.0 thrives on natural language + precise referencing:

1. Upload Assets First: Add images/videos/audio, then reference them in your prompt using @ tags (e.g., @Image1, @Video2, @Audio1).
2. Structure Your Prompt:
   • Describe the overall scene and style.
   • Assign roles to references explicitly.
   • Specify camera, motion, timing, and audio cues.

Example Prompts:

Basic Text-to-Video: A futuristic cyberpunk city at night, neon lights reflecting on wet streets, flying cars zooming past, cinematic lighting, dynamic camera pan.

Multi-Modal with References: Create a 10-second 16:9 music video: @Image1 as the female dancer in a flowing red dress, @Video1 for energetic choreography and camera movements, @Audio1 to sync beats with generated sound effects and background music. Dramatic lighting, smooth transitions between shots.

Video Extension/Edit: Extend the uploaded video by 5 seconds: keep the same character style from @Image2, add dramatic reveal with slow-motion camera zoom, match @Audio1 rhythm.

Best Practices:

• Be specific about references: "Use @Video1's exact camera movement and @Image1's character appearance."
• Include timing cues: "Shot 1: wide establishing, Shot 2: close-up action."
• For audio: "Generate lip-synced dialogue matching the uploaded voice clip, add ambient crowd sounds."
• Iterate: Generate, then upload the result as a new reference for refinements.
