Okay, got it figured out after seeing something and then catching something
while watching another video...
It *is* something that happens apparently when it's dark outside. I guess this
camera or something in the Motion app lowers it when it gets dark and a lot
less light, especially these past few nights with heavy clouds and rain during
the evenings.
I was watching a video and it happened to be the next in line about a half
hour after another before it was still 'dark' outside, but this one there was
finally some light and voila...30 fps.
Thanks for the assistance, tosiara. It got me looking closer at the videos and
catching the not-actually a 'problem', heh.

It's a hard-coded 4 which is "regular". It would be nice to have that as a
config option.
