Trailers from Mobile And PC Games on YouTube - Copyright Issue?

Hey everyone!

I have got YouTube channel with mobile games, so I create own gameplays with screen recorder on my smartphone but I see that on YouTube are channels with games trailers. These YouTubers doesn't create these trailers. So may I add (besides my own gameplays) trailers from mobile games and maybe on another YT channel trailers from PC games or is this a case of copyright infringement on YouTube?

Thanks!

No, you should only add content you own, and there are even lists I have seen that some game companies prohibit you from gameplay, as they don't want you making money from their games. You should seek out these lists too, if you're going to keep at it, make sure you keep everything up above board, and do your homework.

The internet isn't a place you should really say "well they do it, so why can't I?" without some qualification lol

I’d personally stick with gameplay + reactions to stay safer.
