Longest kill of the game camera (overwatch/cod like)

Hey guys, im new in ue4 and game making, but i was wondering about that, how can i make something like “play of the game”. It’s the time where every player on multiplayer server, usually at the end of game. Lets say i want to do final kill cam of the round like in CoD 6 (and others), where the final kill camera even followed throwing knife. So, what i am looking for is longest kill camera, which will be played to all online players on the same server, at the end of game with following “bullet projectile” trajectory and knowing longest kill. Can someone help me? I couldnt find any tutorial, and i am pretty new, so i dont think i can do it all by myself, i need a lot of help from you guys, but i dont think it is bad question.
