Seamless Video Merging with FFMPEGAPI.net: A Guide for Developers

June 2026 FFMPEG API Team

In today's fast-paced digital landscape, automating video processing tasks is essential for developers creating content-rich applications. The Video Merge API from FFMPEGAPI.net offers a robust solution for merging videos seamlessly. This article explores how to use this powerful tool in your workflows, especially for AI agents and content pipelines.

Understanding the Video Merge API

The Video Merge API allows developers to concatenate multiple video files into a single MP4 file efficiently. It handles various video formats, normalizes them as needed, and offers options for audio replacement, custom output dimensions, subtitle burn-in, and watermark overlays.

  • Concatenates one or more video files.
  • Supports optional audio replacement.
  • Allows customization of output dimensions.
  • Enables subtitle burn-in from external files.
  • Supports adding watermark images.

API Endpoint and Parameters

To get started with merging videos, you'll want to use the POST method at the endpoint /api/merge_videos. Below are the parameters required for making a successful API call.

  • video_urls (required): An array of video URLs to merge.
  • audio_url (optional): A URL for the audio track you want to use.
  • dimensions (optional): Specify output dimensions like 1920x1080.
  • subtitle_url (optional): URL for subtitles to burn into the video.
  • watermark_url (optional): URL for a watermark image.
  • async (optional): Process the job in the background if set to true.

Making a Request with cURL

You can easily make a request to the Video Merge API using cURL. Here's a practical example that merges two videos and sets the output dimensions.

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"}'

Integrating with Python

If you prefer to work with Python, you can use the requests library to interact with the Video Merge API easily. Below is a simple example.

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())

FFMPEGAPI.net provides a powerful and easy-to-use Video Merge API that simplifies the process of concatenating multiple videos. With its robust features, API-key authentication, and no server management required, it's the ideal solution for developers looking to integrate video automation tools into their applications, particularly for AI agents and content workflows.
