ytget (YouTube Video Downloader) permits you to download selected YouTube videos through the command line.
It doesn't get much more simple than this app. To use ytget, run ytget.exe 'link to youtube video' and the video will download in the same directory as ytget.exe with the file name 'video title' - 'youtube id.mp4' in the highest quality available (up to 720p).
For example, we used our Windows Repair tutorial video during testing, entered ytget.exe https://www.youtube.com/watch?v=WuloJRoNc_M; it will download the video as Windows Repair Version 4 What's New & Tutorial - WuloJRoNc_M.mp4 providing you with a confirmation that the video is downloading and has finished successfully. Once completed, it can then be played through your default media player.
ytget is a nice option for quick and easy video downloads without configuring or navigating through a cluttered UI -grab, download, and go.
