This article explores how to utilize the AI Captions endpoint of FFMPEGAPI.net to enhance your video content effortlessly.

What is FFMPEGAPI.net?

FFMPEGAPI.net is a hosted REST API designed for FFmpeg-powered video and audio processing. It allows developers to access advanced media processing capabilities without the hassle of server setup or infrastructure management. With API-key authentication, users can easily integrate the service into their workflows.

The AI Captions Endpoint

The AI Captions endpoint (/api/videos/add-tiktok-captions) offers a simple way to transcribe video content and generate stylized captions that are perfect for platforms like TikTok. By extracting audio from the video, the API transcribes the speech, providing word timestamps and rendering beautifully styled captions back into the video.

How to Use the AI Captions API

To use the AI Captions API, you need to send a POST request with specific parameters. The most crucial parameter is the video URL, but you can also customize the caption style and positioning to suit your needs.

Below are the parameters you can use when calling the endpoint:

  • video_url (required): URL of the video to process.
  • subtitle_style (optional): Choose from styles like plain-white, yellow-bg, pink-bg, blue-bg, or red-bg. Default is plain-white.
  • language (optional): Specify language code or use 'auto'. Default is auto.
  • aspect_ratio (optional): Choose from 16:9, 9:16, 4:3, or 3:4. Default is 9:16.
  • max_chars_per_line (optional): Limit caption wrapping from 5 to 80 characters. Default is 20.
  • max_lines (optional): Set maximum lines for captions from 1 to 4. Default is 1.
  • position (optional): Set caption position to top, center, or bottom. Default is bottom.

    'position': 'bottom'
}
response = requests.post(url, headers=headers, json=data)
