How to Add a Watermark to Your Videos

The endpoint for adding a watermark is simple and powerful. To overlay a watermark image onto a video, you can make a POST request to the /api/add_watermark endpoint, providing the necessary parameters such as video URL, watermark URL, position, and scale.

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

url = 'https://www.ffmpegapi.net/api/add_watermark'
headers = {'Content-Type': 'application/json'}
data = {
    'video_url': 'https://example.com/video.mp4',
    'watermark_url': 'https://example.com/logo.png',
    'position': 'bottom-right',
    'scale': 0.2
}
response = requests.post(url, json=data, headers=headers)
print(response.json())

Understanding the Parameters

When using the add watermark endpoint, you must provide specific parameters to define the behavior of the watermark overlay. Understanding these parameters is essential for effective video processing.

  • video_url: The URL of the video you want to process (required).
  • watermark_url: The URL of the watermark image to overlay (required).
  • position: Defines where the watermark will be placed on the video (optional). Default is bottom-right.
  • scale: Sets the width of the watermark as a fraction of the video width (optional). Default is 0.25.
  • async: If true, the API returns a job_id immediately and processes the watermarking in the background (optional).
