If your site uses self-hosted Video Files, then you probably want to host those files on a third-party server which is dedicated to file hosting such as Amazon S3 , Dropbox or Vimeo. VideoPro supports the use of direct video file, so it does not matter if your files are on your server or on another servers. Thus, you can upload your videos to Amazon S3 and get the direct link to use. You can use a plugin like WP Offload S3, WP Cloud Assets to do the job. This plugin helps you to upload your files (images, videos, documents) to your Amazon S3 account, then return a link for you.
