Hello, can someone explain the difference between the three shutter types in the Movi app? Right now, I have to switch the Aux 2 lever down to start recording on my Sony A7SII and to stop recording I have to switch it back to the middle and then back down to the bottom position. Is it possible to set it up so that I can start recording by moving the switch to the bottom position and then stop recording by moving the switch back to the middle? Any help would be greatly appreciated, thanks...
