OBS Studio is pretty good for pasting together several sources
(including application windows) into one or several "scenes" and then
recording (or streaming, or injecting into a videoconference via
v4l2loopback device) a sequence of live sources embedded into switched
scenes.

Check out <https://youtu.be/Vn1f70IH-Es?t=755> for some stuff where I
pasted commentary over the slides of a presentation and then did a
mix-in commentary with a preexisting video, bringing in various (live)
application windows to illustrate what I am talking about.

While several such passages (and the transitions) were done with OBS
Studio, the final output was then stitched together using Shotcut.  Also
the live commentary was overlong and I had numerous excursions into
irrelevant matter: cutting stuff out from the original OBS Studio take
was also done in Shotcut.
