Then I probably wasn’t clear enough, because I want to get real and virtual footage in seperate takes:
I want to have someone play the game in VR. I want to simultaneously record the person with a real camera and record a replay. After the game is finished, I stop recording with the real camera, disable the HMD (so the game is now showing normally on the Monitor) and start playing the replay. Then I record the game on my monitor with the replay going on with OBS, Fraps, plays.tv, Shadowplay, whatever.
I hope I am being clear enough now. 
English isn’t my first language.
