Have you ever wanted to create a gaming or reaction video, but couldn't control your facecam when editing, so your audience has to keep looking back and forth between the footage and your reaction? That's frustrating for everyone involved!
I had this problem, and it took me forever until I figured it out. Now, I'm going to show you not only how you can set up OBS to capture your Facecam and Display seperately, but I'll also give you some pointers on how you can edit your Facecam for greater effect in Premiere Pro!
