At some venues, when we setup, we have unique camera mounting constraints. Sometimes we have to mount a camera upside down (hang it from the ceiling for example). No problem, in vMix we just rotate the video 180 degrees. The problem is, instant replays don't honor that 180 degree rotation. We have to send the camera feed to one of the outputs, then set the instant replay to capture from that output. Not very efficient. It would be nice if instant replays had a "Use Source Settings" for Position just like it does for color correction.
