This video quality will be applied to the online media opened from video sharing sites like YouTube.
But what if you wanted to choose the quality/resolution of the online video that VLC loads from YouTube? There is an advanced option that allows us to select Full HD (1080p), HD (720p), Standard Definition (560p or 480p), Low Definition (360p), and Very Low Definition (240p). The player will try to load the best video resolution that is feasible with the current connection. The best quality that it fetches depends on a number of factors like the speed and bandwidth of your internet connection. When opening videos from YouTube and other video-sharing sites, VLC tries to get the best quality of the video possible.
