I'm using KdenLive for editing, and it's pretty good -- at least, its 
capabilities are well beyond mine.  And at $0, its price is infinitely 
better.

The muy-expensivo camera is my cell phone.  It was realizing that I had 
something ON HAND that would take adequate video that really pushed me 
over the edge.

As for simple recording and editing mistakes, the points that will be 
different next time are:

1: I'm working off of (essentially) a bunch of slides, and you can see me 
looking at them as I talk.  I certainly don't like the looks of it.

2: There's a number of places where swear words, tongue-twists, and nose-
scratching was edited out on-the-fly, causing jumps in the video.  Again, 
they detract from the video.

Instead of trying to do the whole video in one take (and failing), I'm 
going to study _one_ slide, _hide it_, turn the camera on, do _that one 
slide's worth_ while _looking at the camera_, turn the camera off, repeat 
until _that slide_ is good enough, turn to the next slide, and repeat 
until done.  Then I'll edit them together with suitable transitions.

This presentation had ten slides, so if I do 90 seconds and flub it, I 
can just stop the camera, take a few deep breaths, and try again.

3: The lighting could be improved.  Just a few lamps off screen would 
have made it better, but I was in "dammit, just get 'er done" mode -- 
which is why it got done.

Not really on the "immediate" list, but room for incremental improvements:

4: The filming spot could be better.  That's my very own desk and 
workbench, just cleaned up for filming.  I'll probably stay here for now, 
possibly with incremental improvements, but if I should happen to get a 
really strong response I'll make a better spot.

5: I'm doing this entirely on my own.  If I can get a camera-wrangler and 
general coach in here while I'm filming that would help.  Fortunately, I 
have under-employed family members.

6: Editing and closed-captioning, ditto.  Unfortunately my general 
attitude toward new things is "dive in and keep screwing up until you get 
it right", while my wife and kids' attitude is "no, won't try unless I'll 
get it perfect".  Maybe I can get one or more of them to take classes...
