In the world of video content creation, adding a personal touch, like a watermark, can enhance your brand's visibility. With FFMPEGAPI.net, developers can programmatically add watermarks to videos without the hassle of managing server infrastructure. This article explores the 'Add Watermark' endpoint and provides practical examples to streamline your video editing workflows.

Overview of the Add Watermark Endpoint

The 'Add Watermark' endpoint is a powerful feature of FFMPEGAPI.net that allows you to overlay a watermark image onto any video. This endpoint is designed to be both flexible and easy to use for developers working on automation, SaaS applications, or content pipelines.

  • Method: POST
  • Path: /api/add_watermark
  • Content Type: application/json
  • Parameters include video URL, watermark URL, position, and scale.

Request Parameters Explained

When you make a request to the '/api/add_watermark' endpoint, you need to provide several parameters to customize the watermark overlay on your video.

The required parameters include the video URL and the watermark image URL. Other parameters, like position and scale, are optional but highly recommended to get the desired output.

  • video_url (string): URL of the video to which the watermark will be added.
  • watermark_url (string): URL of the watermark image.
  • position (string, optional): Placement of the watermark (e.g., top-right, bottom-left). Default is bottom-right.
  • scale (number, optional): Width of the watermark as a fraction of the video width, ranging from 0.05 to 1.0. Default is 0.25.
  • async (boolean, optional): If true, returns job_id immediately for background processing.

Making a Request to Add a Watermark

To illustrate how to use the 'Add Watermark' endpoint, here's a practical example using cURL. This example assumes you have a valid API key from FFMPEGAPI.net.

You'll send a POST request with the required parameters to overlay the watermark on your video.

curl -X POST https://www.ffmpegapi.net/api/add_watermark \ 
-H "Content-Type: application/json" \ 
-H "Authorization: Bearer YOUR_API_KEY" \ 
-d '{"video_url": "https://example.com/video.mp4", "watermark_url": "https://example.com/logo.png", "position": "bottom-right", "scale": 0.2}'
