In the fast-paced world of video content creation, adding subtitles is an essential step. Whether you're automating workflows for AI agents or developing a SaaS application, FFMPEGAPI.net offers a seamless solution. This blog explores how to use the Add Subtitles API to burn ASS/SSA subtitles into your videos without the hassle of server management.

Understanding the Add Subtitles API

FFMPEGAPI.net provides a robust REST API for video and audio processing, and one of its most powerful features is the Add Subtitles endpoint. This feature allows developers to burn ASS/SSA subtitles directly into their video files with a simple API call.

  • No need for complex FFmpeg installations.
  • Simple API-key authentication for secure access.

How to Use the Add Subtitles Endpoint

To add subtitles to a video, you'll use the POST /api/add_subtitles endpoint. This endpoint requires two key parameters: the URL of the video and the URL of the subtitle file. You can also choose to process the request asynchronously.

  • Method: POST
  • Content-Type: application/json
  • Required Parameters: video_url, subtitle_url
  • Optional Parameter: async (to process in the background)
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"}'
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'
}
