Live Video "Editor"/Cutter for concert

[FunnyPocketBook]

Hello

My school asked me to arrange the electronics for an upcoming concert so one can walk around with a live camera, play movie sequences and project both pictures on the wall.
Basically, I am looking for a software that kinda works like a live cutting program in TV studios.
Lets say the live camera is Picture A, the movie sequences are Picture B, C, D etc.
Both should be projected on the wall (not simultaneously)

Example: First. Picture A is projected, then (at the touch of a button) a fade out to Picture B, then a dissolve to Picture C etc.

Is there a program that isn't too complicated/that is self-explaining (I've already got experience with Adobe Premiere etc.)?

vMix is great. I've used it and it's simple to learn. I'm considering buying it also. It's a pro program and it's $60. They give you 60 days to test it. Google it and check out the pro forums. Others programs (Wirecast, VidBlaster) use the CPU, vMix uses hardware acc. which users say makes for easier load on the computer. Open Broadcaster software is free and it probably will do what you want also but the interface is not as intuitive as vMix for me.

I have used ManyCam https://manycam.com/ to do what I think you are asking about, and it seems to work great.
