What is the Text Overlay Captions Endpoint?

Using the Text Overlay Captions Endpoint

To use the Text Overlay Captions feature, you must send a POST request to the endpoint: `/api/videos/add-text-overlay-captions`. This request requires certain parameters, such as the video URL and the text you want to overlay.

  • Video URL: A valid URL to the video file.
  • Text: The caption lines, separated by newlines.
  • Subtitle Style: Choose from styles like plain-white or yellow-bg.
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'
data = {
    "video_url": "https://example.com/video.mp4",
    "text": "First line\nSecond line",
