footage vr game blueprint

Hi, im new in unreal, im gonna to make a vr game, which have just footage clips and I would like to know if anyone can help me to create some kind of “button” or “action” to change from one screen to another. I wont use any 3d stuff, just clip footage from an Samsung gear 360. Is there any blueprints already that can help me with that? Maybe is a stupid question but im totally new with unreal.
