I'm trying to make a 4K video. The clips that I have are 3840x2160. When I try to change the video properties, I use the 4K 30 fps template. When I try to apply these settings, Movie Studio 13 changes it back to 1920x1080 at 30 fps. Any suggestions?
See Steve G's post here and MSP 13 Overview, Format Support.
Does the OP have the basic Movie Studio 13 (which may be different) or the Platinum version?
