How to Use Seedance 2.0: A Step-by-Step Guide
Seedance 2.0 is ByteDance's AI video generator that creates cinematic-quality videos from text, images, video, and audio. This guide walks you through the three steps: write a prompt, upload references, and generate.
Step 1: Write Your Prompt
Describe the video scene you want. Be specific about action, camera movement, lighting, and mood.
- Use 5 to 5,000 characters
- Include details like "slow push-in", "warm sunset lighting", or "handheld tracking shot"
- The AI uses your prompt to autonomously plan camera angles and scene composition
Step 2: Upload Reference Files (Optional)
Seedance 2.0 accepts multimodal input — combine up to 12 reference files in a single generation:
Supported Inputs
| Type | Limit | Use For |
|---|---|---|
| Images | Up to 9 | Character appearance, style, scene composition |
| Video clips | Up to 3 (15s each) | Camera movement, choreography, editing rhythm |
| Audio tracks | Up to 3 (15s each) | Lip-sync dialogue, background music, ambient sound |
Common Workflows
- Music video — Upload a song + describe the visual style. Seedance 2.0 generates lip-synced video with matching visuals.
- Short film — Provide character reference images + a scene description for multi-shot sequences with consistent characters.
- Style transfer — Upload a reference video for camera work + a photo for character appearance. Combine both in one generation.
Step 3: Generate and Download
Hit the Generate button. Seedance 2.0 uses a 4.5B-parameter dual-branch diffusion Transformer — one branch handles visuals, the other generates synchronized audio.
