I really did kind of know, but I was wondering if this was a
programmable feature.

This is just 640x480 video, but it's evidently recorded in a somewhat
compressed format; I think they quote 48 minutes of video for 1 GB.
Post-processing on a PC could/should get that down a fair amount.

In any case, the quality is good enough for the 11 year old to figure
out the importance of holding the camera steady, of having the subject
in your frame, and, when doing voice overs, to slow down a bit when
you talk. Still, just under $100 for a portable device that can do
this at all is pretty impressive in my book.

Without knowing the resolution, I'm not really sure if that's good or
bad. Obviously, getting this into a reasonably compressed form is
important, which is why it's so cool that FFmpeg and friends are
around these days.
