This article will guide you through the process of using our hosted API to add ASS subtitles to your videos effortlessly.

Why Choose FFMPEGAPI.net?

FFMPEGAPI.net provides a powerful REST API for video and audio processing, removing the need for developers to manage FFmpeg infrastructure themselves.

Our user-friendly API allows you to quickly implement video editing features, including subtitle burning, in your applications, saving you time and resources.

  • No server setup required.
  • API-key authentication for secure access.
  • Ideal for automation in SaaS applications.
  • Great for enhancing content pipelines and AI workflows.

Using the Add Subtitles Endpoint

The Add Subtitles endpoint allows you to burn ASS subtitles into a video file with a simple POST request. This endpoint handles the downloading of both the video and the subtitle file, making the process straightforward.

The endpoint path for this feature is `/api/add_subtitles`. You will need to provide the URL of the video and the subtitle file.

  • Method: POST
  • Content Type: application/json
  • Parameters required: video_url, subtitle_url
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'
}

response = requests.post(url, json=data)
print(response.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"}'

Additional Options for Your Workflow

You can also choose to process the subtitle burning in the background by setting the 'async' parameter to true. This allows your application to continue working without waiting for the processing to complete.

This is particularly useful for applications that require high performance and quick responses, such as real-time video processing systems.

  • Set 'async' to true for background processing.
  • Receive a job_id for tracking the process.
