Seedance 2.0: Stable Video Gen via Vercel AI Gateway

Seedance 2.0 Strengths for Production Video

Seedance 2.0 excels in motion stability and fine details across frames, delivering consistent results in complex scenes with facial expressions and physics. It natively generates synchronized audio supporting multiple languages and dialects. Choose Standard variant for highest quality or Fast for quicker generation at lower cost—both share full capabilities. Key features include text-to-video, image-to-video, multimodal reference-to-video (combine image/video/audio refs), video editing/extension, pro camera moves, multi-shot compositions, and in-video text rendering. Use aspect ratios like 16:9, resolutions like 720p, and durations up to 10s in prompts describing scenes, motion, and audio.

Integrate with One Model ID in AI SDK

Set model: 'bytedance/seedance-2.0' or '-fast' in Vercel's AI SDK experimental_generateVideo for instant access—no Bytedance account required. Test in AI Gateway Playground.

Text-to-video: Prompt scenes directly:

const { videos } = await generateVideo({
  model: 'bytedance/seedance-2.0',
  prompt: `Black triangle sticker peels off laptop...`,
  aspectRatio: '16:9',
  resolution: '720p',
  duration: 5,
});

Image-to-video: Animate input image per prompt, preserve visuals:

const { videos } = await generateVideo({
  model: 'bytedance/seedance-2.0',
  prompt: { image: catImageUrl, text: 'The cat is celebrating...' },
  duration: 10,
  providerOptions: { bytedance: { generateAudio: true } },
});

Reference-to-video: Mix refs for style/motion/sound control:

const { videos } = await generateVideo({
  model: 'bytedance/seedance-2.0',
  prompt: 'Replace the cat in [Video 1] with the lion from [Image 1].',
  duration: 10,
  providerOptions: { bytedance: { referenceImages: [Image1], referenceVideos: [Video1], generateAudio: true } },
});
