Using the Add Subtitles Endpoint

To burn ASS subtitles into a video, you can utilize the Add Subtitles endpoint provided by FFMPEGAPI.net. This endpoint allows developers to specify a video and subtitle URL, and the API takes care of the rest.

Here's how to make a POST request to the Add Subtitles endpoint.

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", "async": false}'
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',
    'async': False
}

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

Parameters Explained

When using the Add Subtitles endpoint, you need to provide specific parameters within your request. Here's a breakdown of the required fields:

  • video_url (string): The URL of the video you want to process.
  • subtitle_url (string): The URL of the ASS/SSA subtitle file.
  • async (boolean): Optional. If true, the job will be processed in the background, and a job ID will be returned immediately.
