Understanding the Add Subtitles Endpoint

The Add Subtitles endpoint is designed to facilitate the burning of subtitles into a video file. By using FFMPEGAPI.net, you can perform this operation with a simple API call, making it ideal for automation, content pipelines, and SaaS applications.

How to Use the Add Subtitles API

To add subtitles to your video, you need to send a POST request to the /api/add_subtitles endpoint. This method requires a video URL and a subtitle URL, along with an optional async parameter to process the request in the background.

Here's a breakdown of the required parameters:

  • video_url: The URL of the video you want to subtitle (required).
  • subtitle_url: The URL of the ASS/SSA subtitle file (required).
  • async: Return a job_id and process the request asynchronously (optional).
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())
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"}'
