I use MS 13 & Mercalli PRO every day.....for me with out either my video's would suffer greatly. Even with stabilized lenses or my Olympus EP5 with 5 axis IBIS, 25% of the stuff I shoot needs some stabilization or rolling shutter correction. IF you own a pervious version of Mercalli you owe to yourself to check out version 4, I only wish it was still a plugin and not a standalone. .........I am not affiliated with MS13 or Mercalli I just use them all the time:).
