Seedance 2.0 Usage Guide
Two ways: Dreamina platform / API integration
Step 1: Register on Dreamina
Visit dreamina.capcut.com, sign up with Google, Apple ID, or email. New users get 260 free credits. Dreamina is the official platform for Seedance 2.0.
Step 2: Choose Generation Mode
Select Video module, then choose: Text-to-Video (describe in words) or Image-to-Video (upload image + motion prompt). Select Seedance 2.0 as the model.
Step 3: Write Your Prompt
Be specific: subject + action + scene + lighting + camera movement (e.g., "cinematic dolly shot", "aerial view"). For I2V, describe only motion changes, not the image itself.
Step 4: Configure Settings
Choose aspect ratio (16:9/1:1/9:16), duration (4-15s), resolution (up to 2K). Use @ tags for references: @style, @motion, @audio, @camera. Costs 6 credits per generation.
Step 5: Generate & Iterate
Click generate, wait 1-3 minutes. Adjust prompt or settings to regenerate. Use Video Extension to continue the story. Iterate for best results.
Step 6: API Integration (Developers)
Use OpenAI-compatible third-party APIs (seedance2api.com, laozhang.ai). Supports text-to-video and image-to-video endpoints. Official Volcengine API coming soon.
