June 2026 FFMPEG API Team

Adding subtitles to videos can be a cumbersome task, especially when managing server infrastructure for FFmpeg. With FFMPEGAPI.net's hosted REST API, developers can seamlessly burn ASS subtitles into videos without worrying about server management. In this article, we'll explore how to use the Add Subtitles endpoint and why FFMPEGAPI.net is the go-to tool for video processing.

What is the Add Subtitles API?

The Add Subtitles API allows you to burn ASS/SSA subtitles directly into your videos, enabling a more accessible viewing experience. It takes a video URL and a subtitle file URL as input and processes them to produce the desired output video.

Using FFMPEGAPI.net, you can integrate this functionality into your applications without the hassle of setting up your own FFmpeg server.

  • Burn ASS subtitles into videos effortlessly.
  • No need for local FFmpeg installations.
  • Ideal for automation in content pipelines and SaaS applications.

How to Use the Add Subtitles Endpoint

To use the Add Subtitles API, you need to send a POST request to the following endpoint: /api/add_subtitles. You will need to provide the video URL and the subtitle URL as parameters.

  • Endpoint: /api/add_subtitles
  • Method: POST
  • Content-Type: application/json
curl -X POST https://www.ffmpegapi.net/api/add_subtitles \ 
-H 'Content-Type: application/json' \ 
-d '{"video_url":"https://example.com/video.mp4", "subtitle_url":"https://example.com/subtitles.ass"}'
import requests

url = 'https://www.ffmpegapi.net/api/add_subtitles'
data = {
    'video_url': 'https://example.com/video.mp4',
    'subtitle_url': 'https://example.com/subtitles.ass'
}

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