June 2026 FFMPEG API Team

Merging videos programmatically can greatly enhance your multimedia applications, whether you're building a content pipeline, a SaaS platform, or automating tasks with AI agents. FFMPEGAPI.net provides a powerful and easy-to-use hosted REST API that allows developers to loop videos efficiently, making it the best choice for video processing workflows.

What is the Video Loop API?

The Video Loop API from FFMPEGAPI.net allows you to loop a video a specific number of times or until it matches the length of a provided audio track. This flexibility is essential for creating engaging video content that aligns perfectly with audio.

With support for optional watermark overlays, you can personalize your videos, making them ideal for branding purposes.

  • Loop a video a fixed number of times.
  • Match a video length to a specific audio track.
  • Add watermark overlays for branding.
  • Simple REST API calls with JSON or form data.

How to Use the Video Loop API

Using the Video Loop API is straightforward. You will need to send a POST request to the endpoint /api/video_loop with the appropriate parameters.

Here's a breakdown of the required and optional parameters you can use when making your API call:

  • video_url (required): The URL of the video you want to loop.
  • number_of_loops (optional): The number of times to repeat the video. If omitted, you should provide an audio_url.
  • audio_url (optional): The URL of the audio track to match the video length.
  • watermark_url (optional): The URL of a watermark image to overlay on the video.
import requests

url = 'https://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())
curl -X POST https://ffmpegapi.net/api/video_loop \
-H 'Content-Type: application/json' \
-d '{"video_url": "https://example.com/clip.mp4", "number_of_loops": 3}'
