Yes, you are right. I thought it croped from top same as from bottom, but I did some primitive test, and it croped video propertly in MHC-BE. I made picture (videos) There are black bars on top and bottom with height of 80px each other bars are see clearly. Sorry, i am not very clever so the picture is wrong as it could only be. But it is only demonstration. So I think no problem.
Each bar is cca 80 pixel height. There are 9 bars. resolution is 1280x720. The videos are long enought. There is source picture too. Sorry, for such primitive test, I hope it helps to see croping in EVR custom preset is properly in MPC-BE even pin info say something different.
Here is series of videos with selfexplaining croping sizes.
