Nokia Lumia 521 - What can I do with the Video Upload app on my Lumia phone?

The Video Upload app helps you share your videos quickly and easily with your friends. It works for all videos shot on Lumia phones. Simply select a video in the Photos app and share or upload it after capturing and trimming with Lumia Video Trimmer through the share option.   You can share your videos over Wi-Fi or a mobile data connection, but be sure to check your network operator's data charges first.
