The endpoint accepts a video URL and an optional watermark image URL, allowing you to brand your videos easily.

  • Endpoint: POST /api/convert_to_vertical
  • Parameters: video_url (required), watermark_url (optional), async (optional)
  • Creates a vertical output that can include a watermark
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"}'
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())

Handling Asynchronous Processing

The API supports asynchronous processing, allowing you to initiate a video conversion and receive a job ID immediately. This feature is beneficial for long processing times, letting you check the status of the job later without waiting for completion.

By setting the 'async' parameter to true, you can enhance the efficiency of your application.

  • Set 'async' to true to process in the background
  • Retrieve job status using the job ID
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}'
