Why does the video take a long time to load and keep buffering?

VikiCS -

Resolution defines the quality of the video. The higher the resolution, the better the quality of the video. In order to play the video in high resolution, you will need a strong network connection. Loading time and buffering may occur frequently when playing high resolution video with bad network connection. We generally recommend to play high resolution videos when you are under a strong WIFI connection, and lower the resolution of video when you are under a 3G network.
