Hey guys, I will be doing some filming indoors.  I was looking to know if any of you have used the shutter priority mode when recording video?  99.9% of my Inspire use has been for pictrues but I am getting more involved with the video.  I have ND filters and like to keep my shutter 2x my fps.  I will be flying indoors next week, there are lots of windows in the place so the light levels will change a lot from when I'm recording the inside of the building to when I'm moving past the window.  Would shutter priority be the best way to go or auto? How about outdoors, do you think shutter priority is useful if you can control over exposure with ND filters.

i believe , shutter priority would be better them auto. because auto has a little bit of  delay to "get used" to a new light environment, like window
