In today's digital landscape, video content is king, especially on social media. Adding text overlay captions can significantly enhance viewer engagement. If you're a developer looking for an efficient way to implement this feature without the hassle of server setup, FFMPEGAPI.net offers the perfect solution with its Text Overlay Captions API.

What is the Text Overlay Captions API?

The Text Overlay Captions API allows you to render user-supplied text lines as timed captions over your videos. This is particularly useful for social media platforms where text can convey essential messages quickly and effectively.

  • Supports multiple subtitle styles including plain-white, yellow-bg, pink-bg, blue-bg, or red-bg.
  • Enables customization of aspect ratios and text positioning for optimal viewer experience.
  • Easy integration into developer workflows with a simple REST API.

How to Use the API

To get started with the Text Overlay Captions API, you can make a POST request to the following endpoint: /api/videos/add-text-overlay-captions. The request requires a video URL and one or more caption lines.

With FFMPEGAPI.net, you can avoid the complexities of managing FFmpeg infrastructure, allowing you to focus on building your application.

  • Endpoint: POST /api/videos/add-text-overlay-captions
  • Content-Type: application/json

-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',
