Adding subtitles to videos can enhance accessibility and viewer engagement. Using FFMPEGAPI.net, developers can seamlessly integrate subtitle burning into their applications without the hassle of managing FFmpeg infrastructure. In this article, we'll explore how to add ASS/SSA subtitles to your videos using our simple API endpoint.

Understanding the Add Subtitles Endpoint

The Add Subtitles endpoint allows you to burn ASS/SSA subtitles directly into a video file, creating a final output that includes the text displayed on the screen.

This is particularly useful for developers working on SaaS applications that require video content to be accessible to a wider audience.

  • Burns subtitles directly into the video file.
  • Supports ASS/SSA subtitle formats.
  • Easy integration with your existing development workflow.

How to Use the Add Subtitles API

To utilize the Add Subtitles feature, you need to send a POST request to the `/api/add_subtitles` endpoint.

This endpoint requires two essential parameters: the URL of the video you want to process and the URL of the ASS/SSA subtitle file.

  • Endpoint: `/api/add_subtitles`
  • Method: POST
  • Content-Type: application/json
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" }'
import requests

url = 'https://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())
