  3. Adjust levels in OBS until shouting/clapping into the mic just clips the top of the red.

  4. Add compression using default settings.

Recording Greenscreens

Canon EOS, Manual movie mode:

shutter speed 1/50 second (I have no idea whether this works because it’s 50FPS or what)

F8.0, film speed 640

White balance: set the Keylights to 5500K and the camera white balance to the same.
