In today's mobile-driven world, vertical videos have become a standard format for engaging viewers on platforms like Instagram, TikTok, and Snapchat. If you are a developer looking to convert horizontal videos to vertical format programmatically, FFMPEGAPI.net offers a powerful REST API that simplifies this workflow without the need for server management. In this article, we will explore how to use the 'Convert to Vertical' endpoint to achieve seamless video conversion.

Understanding the Convert to Vertical API Endpoint

FFMPEGAPI.net provides a dedicated endpoint for converting horizontal videos to vertical format. This is particularly useful for applications that require mobile-friendly content. The endpoint allows you to specify a video URL and optionally include a watermark to enhance branding.

To make use of this API, you don't need to set up any infrastructure or manage FFmpeg installations. This makes it perfect for developers working on automation, SaaS applications, or content pipelines.

  • No server setup or FFmpeg infrastructure management required.
  • API-key authentication ensures secure access to your workflows.
  • Ideal for developers looking to automate video processing in their applications.

Using the Convert to Vertical Endpoint

To convert a video, you'll need to send a POST request to the '/api/convert_to_vertical' endpoint. The required parameter is the 'video_url', while you can optionally add a 'watermark_url' if you want to include a watermark in your output.

Additionally, you can choose to process the request asynchronously by setting the 'async' parameter to true. This allows you to receive a job ID immediately and handle processing in the background.

  • POST Method: /api/convert_to_vertical
  • Required Parameter: video_url (string)
  • Optional Parameters: watermark_url (string), async (boolean)
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"}'
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"}

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