So after fiddling with it some more and putting more thought into a work around solution, I’ve settled on something that works so split screens have absolute precision
— use the left most video output border as the starting reference point. This will require video clip export
as a part of the process, and I no longer have to do x- and y- axis coordinate guesstimates. The video omits using the a custom setting option, but once you get the crop area to your desired specifications, then set it for faster work flow.
