Subtitling videos can enhance accessibility and viewer engagement. With FFMPEGAPI.net's hosted REST API, developers can add ASS subtitles to their videos effortlessly. This article dives into the 'Add Subtitles' endpoint, which allows seamless integration of subtitles into any media workflow.

Overview of the Add Subtitles Endpoint

The 'Add Subtitles' endpoint provides a straightforward method for burning ASS/SSA subtitles directly into a video. This is especially beneficial for content creators and developers looking to automate their media processing workflows.

  • Simple and efficient integration with your existing applications.
  • No need for server setup or management of FFmpeg infrastructure.
  • Supports both synchronous and asynchronous processing.

Using the Add Subtitles API

To use the Add Subtitles API, you'll need to send a POST request to the endpoint: /api/add_subtitles. This API call requires the video URL and the subtitle file URL, ensuring a smooth integration process.

  • Video URL: The URL to the video you want to process.
  • Subtitle URL: The URL to the ASS/SSA subtitle file.
  • Async option: If set to true, the request returns a job_id for background processing.
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"}'
import requests

url = 'https://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())
