How to Add Subtitles Using the API

To add subtitles to your video, you will use the POST method at the '/api/add_subtitles' endpoint. This endpoint allows you to burn subtitles directly into your video, making it ready for distribution across platforms.

Here’s a breakdown of the parameters you need to provide:

1. **video_url**: The URL of the video you want to process.

2. **subtitle_url**: The URL of the ASS/SSA subtitle file.

3. **async** (optional): If true, the process runs in the background and returns a job ID immediately.

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", "async": false}'
import requests

url = 'https://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)
