well, for anyone interested..... I solved the video stutter mystery. My raw footage has no stutter, but my edited video had the stutter, and was horrid during panning. Turns out that my editing software (Pinnacle Studio 22) has an autodetect feature that supposedly automatically sets up the frame rate and resolution of your footage. After examination and some trial and error, I learned that my footage, shot at 24 frames/sec, was being processed at 25 frames per second. Once I discovered the dropdown menu, I got that corrected, the now the footage is very clean... even quick panning is clear. BTW, I have used Pinnacle Studio now for many years. I bought the latest version, Studio 22 Plus, for only $59. This app has full color correction, grading, great audio mixing capabilities, hyperlapse, video reversal, tons of transitons, titles, you name it....and is pretty intuitive to use, and runs well without crashes on a modest computer. Not Adobe Premier, but light years beyond Windows Movie Maker, or half baked free trial versions of otherwise expensive editing programs. Lots of You Tube tutorials, too.
