In the age of digital content, subtitles play a crucial role in making videos accessible to a wider audience. Whether you're building a SaaS application or automating video processing, adding subtitles can enhance user experience. FFMPEGAPI.net offers a powerful hosted REST API that allows you to burn ASS/SSA subtitles into videos effortlessly. In this article, we will explore how to utilize the Add Subtitles endpoint effectively.

What is the Add Subtitles API?

The Add Subtitles API at FFMPEGAPI.net is designed to simplify the process of integrating subtitles into videos. By sending a request to the /api/add_subtitles endpoint, developers can easily download a video and an ASS/SSA subtitle file, then burn the subtitles directly into the output video.

  • Supports ASS/SSA subtitle formats.
  • Perfect for video applications and content pipelines.
  • No need for local FFmpeg installation or server setup.

How to Use the Add Subtitles API

To get started, you need to make a POST request to the /api/add_subtitles endpoint. The request should include both the video URL and the subtitle URL. Additionally, you can choose to process the request asynchronously by including the 'async' parameter.

  • Make sure to provide valid URLs for both video and subtitle files.
  • Asynchronous processing is ideal for large videos, allowing you to retrieve a job ID immediately.
curl -X POST https://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", "async": true }'
import requests

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

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