Version 17, Rendered Video flickering every second, on beat

First video using Movie Studio 17. Final video flickers or flashes every second- in time with the video (like a metronome). I've used early versions of M.S. and never had this problem. Only thing I can think of is I cut and pasted PowerPoint slides into this video...not sure that would cause this. Thoughts?
