I just upgraded to the new version of Photostory 2018 and don't really see big major changes except that my uploaded HD videos are now jumpy and choppy. That is also true for the scrolling titles. My previous version was 2015 and had no choppy or jumpy videos or titles. I'm using the same DSLR and my computer is more than adequate with 12 GB memory and an Intel i7 processor with a Radeon video card. What can be done to correct this problem or am I forced to uninstall and revert back to the 2015 version. I'm using all the default settings in the program.
