Using the Add Subtitles Endpoint

One of the main features of FFMPEGAPI.net is the ability to burn ASS/SSA subtitles into videos through the Add Subtitles endpoint. This is particularly helpful for developers looking to enhance video accessibility and reach a broader audience.

The endpoint allows you to download a video and a subtitle file, and then efficiently integrates the subtitles into the output video.

  • Endpoint: POST /api/add_subtitles
  • Input parameters: video_url, subtitle_url, async
  • Content Type: application/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", "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())
