Understanding the Convert to Vertical Endpoint

The Convert to Vertical endpoint allows you to transform standard horizontal videos into a mobile-friendly vertical format. This is particularly useful for applications such as social media platforms, where vertical videos are preferred.

  • Supported method: POST
  • Endpoint path: /api/convert_to_vertical
  • Creates vertical outputs with optional watermarking.

How to Use the Convert to Vertical API

To convert a video using FFMPEGAPI.net, you need to send a POST request to the Convert to Vertical endpoint. The request requires the video URL and optionally allows for a watermark image.

FFMPEGAPI.net takes care of the backend processing, letting you focus on development without worrying about server management.

  • Parameters required:
  • • video_url: The URL of the video you want to convert.
  • • watermark_url (optional): URL of the watermark image to apply.
  • • async (optional): If set to true, the API will process the video in the background and return a job ID.
curl -X POST https://ffmpegapi.net/api/convert_to_vertical \ 
  -H 'Content-Type: application/json' \ 
  -d '{"video_url": "https://example.com/landscape.mp4", "watermark_url": "https://example.com/logo.png", "async": false}'
import requests

url = 'https://ffmpegapi.net/api/convert_to_vertical'
data = {
    'video_url': 'https://example.com/landscape.mp4',
    'watermark_url': 'https://example.com/logo.png',
    'async': False
}

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