June 2026 FFMPEG API Team

In the world of video content creation, adding text overlays can significantly enhance viewer engagement. With FFMPEGAPI.net, developers can leverage a powerful hosted REST API to automate video processing tasks, including the addition of timed text overlay captions without any server setup. This guide will walk you through the process of using the Text Overlay Captions endpoint to enrich your video content.

What is the Text Overlay Captions Endpoint?

The Text Overlay Captions endpoint allows you to render supplied text lines as timed captions over your videos. This is particularly useful for content creators looking to improve accessibility or emphasize key messages in their videos.

  • Supports multiple caption lines.
  • Customizable subtitle styles and positions.
  • Easy integration into automation workflows.

How to Use the Text Overlay Captions Endpoint

To use the Text Overlay Captions feature, you'll need to send a POST request to the /api/videos/add-text-overlay-captions endpoint with the required parameters. This is where you can specify the video URL, the text to display, and additional styling options.

  • video_url: URL of the video file to process (required)
  • text: The lines of text to overlay (required)
  • subtitle_style: Optional styling for the caption
  • aspect_ratio: Specify the video's aspect ratio
  • position: Where on the video the captions appear
  • duration_per_line: How long each line of text displays
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',
    'duration_per_line': 4
}

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