Comparing the stabiliser from VMS12 to the one in VMS10 I noticed that the rolling shutter correction works in VMS12 better than in VMS10; however, in VMS12 you get glitches in the footage, so the final result is worse than in VMS10.
I used VMS12 64 bit and applied it to HD footage of a Sony camcorder HDR-SR11E and of a Nikon Coolpix AW100 camera
