What is the Text Overlay Captions Endpoint?

Using the Text Overlay Captions Endpoint

To use the Text Overlay Captions feature, you'll send a POST request to the /api/videos/add-text-overlay-captions endpoint. This request requires specific parameters to customize how your captions will appear on the video.

  • video_url: The URL of the video to overlay captions on.
  • text: The caption lines you wish to display.
  • subtitle_style: Optional style for the captions (default is 'plain-white').
  • aspect_ratio: Defines the video aspect ratio (default is '9:16').
  • position: Determines where the captions will be displayed (default is 'center').
  • duration_per_line: Time each caption appears (default is 5 seconds).
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',
