Automate Video Editing with FFMPEGAPI.net: Adding Subtitles Made Easy

June 2026 FFMPEG API Team

In today's digital landscape, automated video editing processes are essential for developers creating applications that require video manipulation. One of the most common tasks is adding subtitles to videos. With FFMPEGAPI.net, you can easily automate this process using our hosted REST API. Our Add Subtitles endpoint simplifies the task of burning ASS/SSA subtitles into a video with just a few lines of code.

Understanding the Add Subtitles Endpoint

The Add Subtitles endpoint is a powerful tool that allows you to burn subtitles directly into a video. This is especially useful for content creators, video editors, and developers who need to integrate subtitles into their workflow seamlessly.

Using this endpoint, you can send a simple POST request that includes the URLs of the video and the subtitle file. The API handles the processing and returns the edited video, making it an efficient solution for subtitle addition.

  • Endpoint Path: /api/add_subtitles
  • Method: POST
  • Content Type: application/json
  • Key Parameters: video_url, subtitle_url, async (optional)

How to Use the Add Subtitles Endpoint

To get started, you need to prepare your API key for authentication. FFMPEGAPI.net provides a secure way to manage API keys, ensuring that your requests are authenticated and your data is protected.

Once you have your API key, you can use the Add Subtitles endpoint to upload your video and subtitle URLs. Here’s a practical example of how to make a request using curl and Python.

curl -X POST https://www.ffmpegapi.net/api/add_subtitles \
-H "Content-Type: application/json" \
-H "Authorization: Bearer YOUR_API_KEY" \
-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'
headers = {'Content-Type': 'application/json', 'Authorization': 'Bearer YOUR_API_KEY'}
data = {"video_url": "https://example.com/video.mp4", "subtitle_url": "https://example.com/subtitles.ass"}

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