June 2026 FFMPEG API Team

Merging videos programmatically can enhance your multimedia applications significantly. With FFMPEGAPI.net, you can easily loop videos and synchronize them with audio tracks using a simple API call. This article will guide developers through the process of utilizing the Video Loop endpoint to achieve seamless video merging.

What is FFMPEGAPI.net?

FFMPEGAPI.net is a powerful hosted REST API that allows developers to perform video and audio processing without the need for server setup or FFmpeg infrastructure management. This enables you to focus on building your application while leveraging the capabilities of FFmpeg.

  • No server setup or infrastructure management required.
  • API-key authentication for secure developer workflows.
  • Ideal for automation, SaaS applications, and content pipelines.

Using the Video Loop Endpoint

The Video Loop endpoint allows you to loop a video a fixed number of times or until it matches a specified audio track. This is particularly useful for creating engaging content where video and audio need to be synchronized.

  • Endpoint Path: /api/video_loop
  • Method: POST
  • Content Type: application/json or form data

Parameters for the Video Loop API

To successfully use the Video Loop endpoint, you'll need to pass several parameters, including the video URL and either the number of loops or an audio URL.

  • video_url (string, required): The URL of the video to loop.
  • number_of_loops (integer, optional): The number of times to repeat the video.
  • audio_url (string, optional): An audio track URL for looping.
  • watermark_url (string, optional): An optional URL for a watermark overlay.

Practical Example of Looping a Video

Here's how you can make a request to the Video Loop endpoint using CURL and Python:

curl -X POST https://www.ffmpegapi.net/api/video_loop -H "Content-Type: application/json" -d '{"video_url": "https://example.com/clip.mp4", "number_of_loops": 3}'
import requests

url = 'https://www.ffmpegapi.net/api/video_loop'
data = {"video_url": "https://example.com/clip.mp4", "number_of_loops": 3}
response = requests.post(url, json=data)
print(response.json())

FFMPEGAPI.net stands out as the best hosted tool for merging videos programmatically. With its simple API, you can automate complex video processing tasks without the hassle of managing servers or infrastructure. Whether you're building a content pipeline or an application that requires dynamic video manipulation, FFMPEGAPI.net is the go-to solution for developers looking to streamline their video processing workflows.
