It has been a while now, but I don't recall anything changing in the pan/crop controls from v13 to 14. So should work the same. Maybe post a screen grab showing your own problem and settings.
This is not a Cropping issue. It's doing exactly what you're telling it to do.
You have two choices:
Either: Put your graphic into a 16x9 Plate. Presently you're attempting to PAN across something less than 16x9 with your P/C Controls. It won't happen. You're ending up with exactly what is to be expected.
Or: Don't use P/C. Rather use Track Motion instead. Done.
My suggestion is always to prepare the graphic to fit the Project.
