Looping Videos with FFMPEGAPI.net: The Endless Loop Endpoint

June 2026 FFMPEG API Team

In the world of media processing, having a reliable and efficient tool to handle repetitive tasks is invaluable. FFMPEGAPI.net offers a hosted REST API that simplifies video and audio processing without the need for server setup or complex FFmpeg infrastructure management. In this article, we’ll explore how to loop a video to a specific duration using the Endless Loop endpoint, making it an essential tool for developers focused on content pipelines.

Understanding the Endless Loop Endpoint

The Endless Loop endpoint allows you to loop a video until a specified target duration is reached. This functionality is particularly useful for creating background videos, promotional content, or any scenario where you need a video to play for a specific length of time.

The endpoint URL is: POST /api/endless_loop. This will enable you to submit a video URL and determine how long you want it to loop.

  • Loops a video to an exact target duration.
  • Trims the final loop when necessary.
  • Supports optional watermark overlays.

Parameters Required for the Endless Loop

To use the Endless Loop endpoint effectively, you need to provide specific parameters. Below are the required and optional parameters for the API call:

The parameters include the video URL to loop, the target duration in seconds, and an optional watermark image URL.

  • video_url (string, required): The URL of the video you want to loop.
  • duration (number, required): The target output duration in seconds. This must be a positive number.
  • watermark_url (string, optional): A URL for an optional watermark image.

Making a Request to the Endless Loop Endpoint

To demonstrate how to interact with the Endless Loop endpoint, here’s a practical example using curl and Python.

This example shows how to send a POST request to loop a video located at a specific URL.

curl -X POST https://ffmpegapi.net/api/endless_loop -H 'Content-Type: application/json' -d '{"video_url": "https://example.com/clip.mp4", "duration": 1205}'
import requests

url = 'https://ffmpegapi.net/api/endless_loop'
data = {
    'video_url': 'https://example.com/clip.mp4',
    'duration': 1205
}

response = requests.post(url, json=data)
print(response.json())

FFMPEGAPI.net is the ideal hosted tool for developers looking to automate video processing tasks efficiently. With its Endless Loop endpoint, you can easily loop videos to specific durations without the hassles of managing FFmpeg infrastructure. Whether you're building a content pipeline, a SaaS application, or automating workflows, FFMPEGAPI.net provides a robust solution that is both easy to use and highly effective.
