Simplifying Video Merging with FFMPEGAPI.net's Video Merge Endpoint

June 2026 FFMPEG API Team

Merging videos is a common requirement in video processing workflows, especially for developers building SaaS applications or automation tools. With FFMPEGAPI.net, you can leverage a powerful, hosted FFmpeg REST API to concatenate videos seamlessly without the need for complex server setups. In this article, we will guide you through using the Video Merge endpoint to simplify your video processing tasks.

Understanding the Video Merge Endpoint

The Video Merge endpoint allows you to concatenate multiple video files into a single MP4 file. It handles the downloading of the specified videos, normalizes them if necessary, and merges them together efficiently.

This endpoint supports several optional parameters, including audio replacement, custom output dimensions, subtitle burn-in, and watermark overlay, making it a versatile tool for developers.

  • Concatenate videos easily with a single API call.
  • Optional audio replacement enhances the final output.
  • Burn subtitles directly into the video for added accessibility.
  • Add watermarks to maintain brand identity.
curl -X POST https://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"}'

Parameters for the Video Merge API

When using the Video Merge endpoint, you need to provide a few key parameters. Here's a breakdown of the required and optional parameters you can use:

The 'video_urls' array is mandatory and should contain at least one URL. The other parameters allow you to customize the merging process.

  • video_urls (required): Array of video URLs to merge.
  • audio_url (optional): Replace audio with a specified URL.
  • dimensions (optional): Set the output video dimensions, e.g., 1920x1080.
  • subtitle_url (optional): Specify a URL for ASS/SSA subtitles to burn in.
  • watermark_url (optional): URL for a watermark image to overlay.
  • async (optional): Process in the background and return a job ID.
import requests

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