  • Content-Type: application/json
  • Parameters: video_url (required), watermark_url (optional), async (optional)
curl -X POST https://www.ffmpegapi.net/api/convert_to_vertical \n-H "Content-Type: application/json" \n-d '{"video_url": "https://example.com/landscape.mp4", "watermark_url": "https://example.com/logo.png"}'

Benefits of Asynchronous Processing

For larger video files or when immediate processing isn't necessary, our API also supports asynchronous processing. By setting the 'async' parameter to true, you can initiate the conversion and receive a job ID, allowing your application to continue working without waiting for the process to complete.

  • Enhances application efficiency by processing in the background.
  • Allows for better resource management in your workflows.
