June 2026 FFMPEG API Team

In today's competitive social media landscape, enhancing video content with captions can significantly boost viewer engagement and accessibility. With FFMPEGAPI.net, you can easily add timed text overlay captions to your videos without the hassle of server management or complex setups. Our hosted REST API simplifies video processing, making it the ideal solution for developers and content creators alike.

What is the Text Overlay Captions API?

The Text Overlay Captions API is a powerful endpoint provided by FFMPEGAPI.net that allows you to render user-supplied text lines as timed caption overlays on videos. This feature is especially useful for social media platforms where attention spans are short, and clear messaging is essential.

  • Render captions at specific intervals.
  • Support for multiple subtitle styles.
  • Customizable position and display settings.

How to Use the Text Overlay Captions API

To use the Text Overlay Captions API, you need to send a POST request to the `/api/videos/add-text-overlay-captions` endpoint. The request must include the video URL and the text you want to overlay. Optionally, you can customize the subtitle style, aspect ratio, position, and duration per line.

  • Supported content types: application/json
  • Required parameters: video_url, text
  • Optional parameters: subtitle_style, aspect_ratio, position, duration_per_line
curl -X POST https://ffmpegapi.net/api/videos/add-text-overlay-captions \ 
-H "Content-Type: application/json" \ 
-d '{"video_url": "https://example.com/video.mp4", "text": "First line\nSecond line", "duration_per_line": 4}'
import requests

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

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