Using the Convert to Vertical Endpoint

Our '/api/convert_to_vertical' endpoint allows you to convert horizontal videos to a mobile-friendly vertical format. This is particularly useful for social media platforms where vertical videos perform better.

The endpoint accepts a few parameters, including the URL of the video you want to convert and an optional watermark image URL.

  • Method: POST
  • Endpoint Path: /api/convert_to_vertical
  • Required Parameters: video_url (string)
  • Optional Parameters: watermark_url (string), async (boolean)
import requests

url = 'https://www.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())

How to Handle Asynchronous Processing

For larger videos or when processing time is a concern, you can use the 'async' parameter. By setting this to true, the API will return a job_id immediately, allowing you to check the status of the conversion later.

  • Set async to true for background processing.
  • Retrieve job status via another API call.
curl -X POST https://www.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": true}'
