What Is Seedance 2.0 API?

Seedance 2.0 API is ByteDance's next-generation AI video generation model, offering both text-to-video and image-to-video capabilities with built-in audio generation.

Creating scroll-stopping content at scale is a challenge every social media team faces. Seedance 2.0 generates complete videos with matching audio from a single text prompt, cutting production time from hours to seconds.

Example use case: A social media management platform that generates daily video content for multiple brand accounts, each with platform-optimized aspect ratios and built-in sound effects.

  method: 'POST',
  headers: {
    'Authorization': 'Bearer YOUR_API_KEY',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    model: 'seedance-1-5-t2v',
    prompt: 'A barista pouring latte art in slow motion, warm cafe lighting, steam rising from the cup, ambient cafe sounds',
    duration: 8,
    resolution: '1080p',
    aspect_ratio: '9:16',
    generate_audio: true
  })
});

2. Product Demo Videos with Sound

E-commerce brands need product videos that look and sound professional. Seedance 2.0's audio generation means you get the satisfying click of a watch clasp, the swoosh of fabric, or the crunch of a snack — all generated alongside the video.

Example use case: An e-commerce platform that transforms product photos into demo videos with realistic sound effects, boosting conversion rates on product listings.

const response = await fetch('https://api.hypereal.com/v1/videos/generate', {
  method: 'POST',
  headers: {
    'Authorization': 'Bearer YOUR_API_KEY',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    model: 'seedance-1-5-i2v',
    prompt: 'The sneaker rotates on a display platform, studio lighting highlights the texture, soft ambient music',
    image: 'https://example.com/sneaker.jpg',
    duration: 6,
    resolution: '1080p',
    aspect_ratio: '1:1',
    generate_audio: true
  })
});

3. Advertising Creative at Scale

Digital advertising requires constant creative refresh to avoid audience fatigue. Seedance 2.0 lets ad teams generate dozens of video creative variations quickly, each with synchronized audio that matches the visual mood.

elif result['status'] == 'processing':
    print('Task ID:', result['id'])
else:
    print('Error:', result.get('error'))

Best Practices

Enable audio for immersive content — The synchronized audio generation is a key differentiator. Use it for social and marketing content where sound matters.
Disable audio to save costs — For silent applications like GIF-style loops or thumbnails, set generate_audio: false to cut costs in half.
Use camera_fixed for stability — Enable this for product shots or scenes where you want a steady frame.
Choose resolution wisely — Use 720p for prototyping and social media, 1080p for final production content.
Leverage aspect ratio options — Seedance supports more aspect ratios than most competitors. Use 21:9 for cinematic, 9:16 for mobile, 1:1 for feeds.
