How do i make a certian video play if I shoot at a certian position on my map

Hi guys!. I’m pretty new to UE4 and i got 2 questions about the type of game I want to create but there are literally no help anywhere.

1:Is it possible to add a transparent videos to a plane, for in case different logos so when i shoot at a specific part of my map that certain video plays, for an example lets say there is a rock a tree and a house and if i shoot the house at a certain spot a video play in front of a house and if i shoot the rock another video play, and it should be instant

2:is it possible to bind a specific video to a key, for in case if i press R the video play of a guy that reloads but the key R disables when the character is out of ammo or full.

Please, any help would GLADLY be appreciated
