When watching a collaboration of live streamers and we want to watch their point of view (POV) at the same time, the usual way would be to open multiple browser windows (not tabs) and load up YouTube in each one.
However, doing this can really slow down our PC and make it lag, especially on a low-spec PC. Additionally, we then have to deal with arranging all those windows so they don't overlap.
Well, there’s a better way! You can watch all your videos in just one browser using this cool site called YouTube Multiplier. It lets you open up to 8 videos at the same time!
Just copy the YouTube links and paste them into the empty boxes (check out the image below for reference). You can also choose how you want to arrange the videos. Just remember to add a title for your mashup before you publish and share it with your friends!
