How to Use LatentSync

  1. Prepare Your Inputs

    • Ensure you have a high-quality audio file accessible via a URL.
    • Select a video file with clear visuals and uploadable via URL.

  2. Submit Your Request

    • Use the model's API endpoint by providing an object with audio_url and video_url fields.
    • Example JSON input: 
      {
  "audio_url": "https://example.com/path/to/your/audio.wav",
  "video_url": "https://example.com/path/to/your/video.mp4"
}

  3. Processing and Generation

    • The model processes the inputs, synchronizing the audio with the video.
    • Wait for the generated video link to be returned in the response.

  4. Review the Output

    • The output will be a JSON object containing the key video with the URL of the generated video.
    • Review the video to verify lip sync accuracy and overall quality.

  5. Integrate into Your Workflow
