As video content continues to dominate online media, adding subtitles is not just a luxury, but often a necessity. Whether you’re building a SaaS application, automating video content, or enhancing your content pipeline, integrating subtitle functionality can greatly improve user engagement. FFMPEGAPI.net provides a seamless way to add subtitles to videos through a simple REST API, allowing you to focus on your application without worrying about server setup or FFmpeg management.

What is the FFMPEGAPI.net Add Subtitles Endpoint?

FFMPEGAPI.net offers a powerful 'Add Subtitles' endpoint that allows developers to burn ASS/SSA subtitles into a video with just a few API calls. This endpoint simplifies the process of video enhancement by taking care of the heavy lifting behind the scenes.

  • Supported file formats: ASS and SSA subtitle files.
  • Instantly burn subtitles into videos without any local FFmpeg setup.
  • Ideal for automation and content pipelines.

How to Use the Add Subtitles Endpoint

To use the Add Subtitles feature, developers simply need to send a POST request to the /api/add_subtitles endpoint with the required parameters. The process is straightforward and can be done in various programming languages, including Python and cURL.

  • Required Parameters:
  • 1. video_url: The URL of the video to which you want to add subtitles.
  • 2. subtitle_url: The URL of the ASS/SSA subtitle file.
  • Optional Parameter:
  • 1. async: If set to true, the API will return a job ID immediately and process the job in the background.
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': True
}

response = requests.post(url, json=data)
print(response.json())
curl -X POST https://ffmpegapi.net/api/add_subtitles \
-H 'Content-Type: application/json' \
