For some reason when I tried to record the Unity IDE Window using the Window Capture source it shows me a preview of the Unity window but then it says "Starting the output file failed". What could be wrong? I am using an HP laptop with Windows 10 Home version 1803 and I made sure that both OBS Studio and Unity are rendering to the Nvidia Graphics card since I have both a Nvidia Graphic card and an Intel Integrated Graphics card in my laptop. I also tried to capture the Unity window using the Game Capture source that didn't work either because it gave me the same error message. I just installed this program and have the default settings.
