suggestions for recording video lessons?

[M. Fioretti]

Greetings,

I have to put together some non-interactive video lessons from my
Ubuntu 19.10 laptop. That, is do something with the laptop and
explaining it, with the audio always on, alternating live video of the
screen (maybe with me in a small picture-in-picture) and of myself
full screen.  And save the whole video for later uploading to a
server.

What is the best software right now to do this on Ubuntu? I do all
sorts of online teaching but did not have this specific need for a
while, and now need to get current asap.

Thank you in advance,
			Marco
