Here are some of the links to prior posts about it, so I don't have to repeat everything and for future reference if anyone searches based on the same issue:

In brief, I wasn't doing anything fancy with the JPGs, I was zooming in on some of them but they were high-resolution files and I couldn't for the life of me understand why the rendered images were so terrible. Lots of folks offered helpful suggestions for tweaking the settings, but nothing seemed to work and I frankly got so frustrated that I gave up on my project for a few months. But recently I went back and tried some more troubleshooting, and I also stumbled across this post which helped me find the missing link between all the information I had received about setting changes and actually resolving the issue:

I'll copy the relevant helpful bit from this post here:
"I downloaded the trial version and was immediately baffled by the fuzzy (out of focus) photos, while the video's were fine. I had set my preferences to MPEG2, 4:3, bitrate of 15000, Frame-based, resampling=Best . . . . I noticed that if I clicked on SHARE and tried to create a video file, only AVCHD would produce clear photos (but only at 16:9). For any other selection (NTSC DVD at 4:3), Videostudio ignored my preferences settings and always did Lower Field First, and bitrates of about 6000 variable. Then I noticed the option "Same as project settings" and when I selected this, it created a perfect slideshow (MPEG2 file) with no fuzzyness."
Bottom line is that no matter what "project settings" I set (from the File menu), when I went to render my project, some default settings kept overriding my setting choices because I was manually selecting render as MPG2 (or whatever) instead of selecting "SAME AS PROJECT SETTINGS" from the list of choices for what file to render as.
This may seem laughably obvious to everyone else, but I didn't realize that my project settings would be totally overrided by selecting anything other than "SAME AS PROJECT SETTINGS" when rendering the file! Doh!
Specifically, I went into my project settings and made sure that everything was set as described above (MPEG2, 4:3, bitrate of 15000, Frame-based, resampling=Best) and then selected SAME AS PROJECT SETTINGS when rendering the file, the blocky/fuzzy image problem was solved.
So if you are having fuzzy or blocky or poor quality JPG still images in when you render your video, FIRST make sure your project settings are tweaked correctly (disclaimer, I haven't figured out yet if the project settings described above are the absolute best, just that they are better than what was happening before) and SECOND make sure you select "SAME AS PROJECT SETTINGS" when you render your file.
Now I'm happily returning to my family video project!
