Nokia has released an exclusive app called YouTube Upload for its Lumia Windows Phone devices. As the name suggests, it’s a simple YouTube uploader app. This app is not yet available for Lumias, I think we need Amber/GDR2 update to download and enjoy this app.
This app helps you to share your videos quickly and easily with your friends, and works for all videos shot on Nokia Lumia phones with Windows Phone 8. Simply select the video in the Photos app and share, or upload after capturing and trimming with the Nokia Video Trimmer through share option.
Share your video over Wi-Fi or a mobile data connection, but be sure to check your network operator’s data charges first.
Download it here from Windows Phone Store for free.
