A question about mocap&facial mocap

I’m practically noob when it comes to animating, so please excuse me even though a question I’m gonna throw sounds really stupid or obvious or whatever to you.

As you know, there are some softwares that provide “Live” function within UE4 client.
(For instance, Faceware Live, Perception Neuron)
And it is my understanding one can record a sequence in UE4.
Then is it possible to use the Live feature to instantly animate a character, record it, and then use that sequence to make an animation asset or an animation blueprint to use in game development without having to deal with other softwares like Motionbuilder, Cinema4D, etc?
(Assuming, of course, rigging is all done)
