June 2026 FFMPEG API Team

In the growing world of video content, developers often face the challenge of merging multiple video files into a single cohesive presentation. With FFMPEGAPI.net, you can achieve this with ease through our hosted REST API, eliminating the need for managing your own FFmpeg infrastructure. This article will guide you through the capabilities of our Video Merge API and show you how to integrate it into your workflow.

What is the Video Merge API?

The Video Merge API allows you to concatenate multiple videos into a single MP4 file. It handles downloads, normalizes the video files, and merges them seamlessly. This API can also accommodate various additional features like audio replacement, custom output dimensions, subtitle burn-in, and watermark overlays, making it a versatile tool for developers.

  • Concatenates multiple video files into one.
  • Supports optional audio replacement.
  • Allows customization of output dimensions.
  • Burns subtitles into the final video.
  • Overlays watermarks for branding.

How to Use the Video Merge API

To utilize the Video Merge API, you'll need to send a POST request to the endpoint: `/api/merge_videos`. The request must be formatted in JSON and include the required parameters such as video URLs that you want to merge.

  • Required parameter: `video_urls` - An array of video URLs to merge.
  • Optional parameters include: `audio_url`, `dimensions`, `subtitle_url`, and `watermark_url`.
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())
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"}'
