June 2026 FFMPEG API Team

In today's fast-paced digital world, automating video editing tasks can save valuable time and resources. FFMPEGAPI.net offers a powerful hosted REST API that allows developers to seamlessly merge multiple videos into a single file. The '/api/merge_videos' endpoint simplifies the process, enabling a quick setup without server management or infrastructure headaches.

Understanding the Video Merge Endpoint

The '/api/merge_videos' endpoint is designed to concatenate videos efficiently. Whether you're developing software for content creation, automation, or SaaS applications, this endpoint provides a straightforward way to combine video files.

The API supports various options, including audio replacement, output dimensions, subtitle burn-in, and watermark overlays, making it a versatile choice for developers.

  • Concatenate videos into a single MP4 format.
  • Normalize video files as needed.
  • Optional audio, dimension, subtitle, and watermark settings.

Parameters for Video Merging

To effectively use the '/api/merge_videos' endpoint, you need to specify several parameters. Here’s a brief overview of the required and optional parameters you can use:

The 'video_urls' parameter is mandatory and must include at least one video URL to merge. Other parameters such as 'audio_url', 'dimensions', 'subtitle_url', and 'watermark_url' allow you to customize the output video.

  • 'video_urls' (array[string]): Required. List of video URLs to merge.
  • 'audio_url' (string): Optional. Replacement audio URL.
  • 'dimensions' (string): Optional. Output dimensions (e.g., 1920x1080).
  • 'subtitle_url' (string): Optional. ASS/SSA subtitle URL for burn-in.
  • 'watermark_url' (string): Optional. Watermark image URL.
  • 'async' (boolean): Optional. Processes the request in the background.

Making Your First API Call

Now that you understand the parameters required for merging videos, let's go through a practical example using a CURL command to make a request to the '/api/merge_videos' endpoint.

curl -X POST https://www.ffmpegapi.net/api/merge_videos \
-H "Content-Type: application/json" \
-d '{"video_urls": ["https://example.com/intro.mp4", "https://example.com/main.mp4"], "dimensions": "1920x1080"}'

Automating Video Merging with Python

You can also use Python for a more programmatic approach to video merging. Below is an example script that demonstrates how to call the '/api/merge_videos' endpoint using the popular 'requests' library.

import requests

url = 'https://www.ffmpegapi.net/api/merge_videos'
data = {
    'video_urls': ["https://example.com/intro.mp4", "https://example.com/main.mp4"],
    'dimensions': '1920x1080'
}

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