Editing - The weird clip

Editing on the MAC's cause some problems, little details which we would have to either sort out or re- do
For example one of our clips loosing its boarder and zooming in

This clip when playing was zoomed in and cut off some off the bottom. Even when we put it back into the editing side, it said it was normal although it wasn't. This is an example of little things that would go wrong which would take time to sort out. We ended up having to re-upload this clip to the computer then put it back onto premiere pro for it to work which was okay!!
