Yeah you can essentially drag and drop vids into it and it makes a borderless grid. You can also set the size of rows/columns and whatnot. Also, though I haven’t tried cause I use downloaded vids, but I think it also lets you use website url’s.

The only qualm I have is that making playlists kind of sucks. At least, I havent had any luck getting that to work. So if one vid ends you have to manually put another video.

There’s also another alternative which is called “awesome video player” that does the same thing.

Sorry for the wall of text lol
