Using the Add Subtitles Endpoint

The 'Add Subtitles' endpoint allows you to easily burn ASS subtitles into a video. This is essential for creating accessible and engaging video content that caters to diverse audiences. The endpoint uses a POST method and requires the video URL and subtitle URL as parameters.

Here's a quick overview of the parameters you need for this endpoint:

  • video_url: The URL of the video you want to process (required).
  • subtitle_url: The URL of the ASS/SSA subtitle file (required).
  • async: Set to true if you want to process the video in the background and receive a job ID immediately (optional).
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'
}

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

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"}'
