FFMPEGAPI.net offers a robust hosted solution that simplifies video automation, particularly for AI agents. In this article, we will explore how to use the Video Merge endpoint to concatenate videos effortlessly, focusing on its features and capabilities.

Understanding the Video Merge Endpoint

The Video Merge endpoint provided by FFMPEGAPI.net allows you to concatenate multiple videos into a single MP4 file. This functionality is ideal for applications that require video aggregation, such as streaming platforms, content creation tools, and automation workflows for AI agents.

  • Concatenate multiple video URLs into one MP4 file.
  • Supports optional audio replacement for customized output.
  • Allows for dimension adjustments and subtitle burn-in.
  • Easily add watermarks to your final video.

Key Features of the Video Merge API

FFMPEGAPI.net's Video Merge offers a suite of features that cater to various use cases. Here’s a breakdown of the parameters you can use:

  • video_urls: An array of video URLs to merge (required).
  • audio_url: An optional URL for replacing the original audio.
  • dimensions: Define the output dimensions like 1920x1080.
  • subtitle_url: Burn in optional subtitles from an ASS/SSA URL.

Making a Video Merge Request

To use the Video Merge endpoint, simply send a POST request to /api/merge_videos with your desired parameters. Here’s a practical example using curl and Python:

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"}'
import requests

url = 'https://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())
