Hey all this is a video related question 
On a windows PC does anyone know how to record this so a reaction video area would be at the bottom of the screen? I normally record my videos with my phone and Youtube tutorials seem to be more for reaction videos while watching something on your PC.
Incase anyone is wondering I don’t want to do a UnlistedLeaf style OMGG *dubstep* reaction I just think it will add some more value to more videos!
I think most people just use a cheap web cam to record themselves since your portion of the video will be so tiny. So use your phone for the video, a webcam connected to your PC for face cam, and there should be a few software options to sync it all up into one video.
Okay makes sense about the cheap web cam so it is so tiny, I will give it a go like that!
Cheers 
Picture-in-picture is very easy to do if you record with two different camera’s and overlay them in editing software . . . all you would really have to do is crop one of the videos and move it to your preferred corner.
