i didnt know my comment about your aim hurt you haha my bad my aim is pretty terrible so i cant say too much, its one of the main reasons im not a huge shooter fan
If you have a green screen setup behind you, then you need to make sure your lighting (ring light, etc.) is consistent on the green screen. In editing, if you use premiere pro, you use the 'ultra key' effect and then you use the dropper to select you green screen from the video and then you can play around with 'matte generation'. I can make a video if you want.
brother your actually an inspiration. recording playthroughs regardless or not if you have many subs. I stopped cuz I don't get any. keep up the good work. if you ever wanna Colab on a Co-op story game I'm down if you are.
I source record both my camera and my game separately with obs. There are videos on RU-vid to show you then I do all my post with premiere pro. I would also invest in a usb or xlr mic!
