June 2026 FFMPEG API Team

In today's world of digital content, enhancing videos with text overlays can significantly improve viewer engagement. FFMPEGAPI.net provides a powerful REST API for developers to add text overlay captions to their videos without the need for server management. This blog post will guide you through the process of using the Text Overlay Captions endpoint to elevate your video projects effortlessly.

What is the Text Overlay Captions API?

The Text Overlay Captions API is designed to allow developers to render user-supplied text as timed caption overlays on a video. This can be particularly useful for creating engaging content where information needs to be highlighted or emphasized.

  • Add multiple text lines as captions.
  • Customize subtitle styles and positions.
  • Specify duration for how long each line appears.

How to Use the Text Overlay Captions Endpoint

To utilize the Text Overlay Captions feature, you will make a POST request to the following endpoint: /api/videos/add-text-overlay-captions.

The request must contain a JSON body with parameters such as video_url, text, and optional settings for style, aspect ratio, position, and duration.

  • video_url: URL of the video to process (required)
  • text: Caption lines separated by newlines (required)
  • subtitle_style: Style options like plain-white or yellow-bg (optional)
  • aspect_ratio: Set the video's aspect ratio (optional)
  • position: Choose from top, center, or bottom (optional)
  • duration_per_line: Control how long each line is displayed (optional)
import requests

url = 'https://www.ffmpegapi.net/api/videos/add-text-overlay-captions'
data = {
    'video_url': 'https://example.com/video.mp4',
    'text': 'First line\nSecond line',
    'duration_per_line': 4
}

response = requests.post(url, json=data)
