The Best Way to Merge Videos Programmatically with FFMPEGAPI.net

June 2026 FFMPEG API Team

If you're a developer working on video processing applications, you understand the importance of efficient and reliable tools. FFMPEGAPI.net offers a powerful hosted REST API for FFmpeg-powered video and audio processing, making it the best choice for merging videos programmatically. In this article, we'll explore the Endless Loop endpoint and how it can simplify your video merging workflows.

Understanding the Endless Loop Endpoint

The Endless Loop endpoint allows you to loop a video until a specified target duration is achieved. It's ideal for scenarios where you need to create content that lasts for a specific time frame, such as background loops for presentations or seamless video segments for social media.

By using FFMPEGAPI.net, you eliminate the need for server setup or managing FFmpeg infrastructure. This approach not only saves time but also allows you to focus on building your application without worrying about underlying complexities.

  • Loop a video to an exact target duration.
  • Supports optional watermark overlay.
  • Handles fractional seconds for precise duration.

How to Use the Endless Loop Endpoint

To use the Endless Loop endpoint, you'll need to make a POST request to the following path: `/api/endless_loop`. The request requires two key parameters: `video_url` and `duration`, with an optional `watermark_url` for adding a watermark to your video.

Here's a breakdown of the required parameters:

  • video_url: The URL of the video you want to loop.
  • duration: The target output duration in seconds (must be a positive number).
  • watermark_url: Optional URL for a watermark image.
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())
