I would recommend this one:
It needs a bit time getting familiar with, but it’s worth it.
And its 100% free.
Overview
However, I’m not sure if it is that what you are looking for. Since this covers more the recording part of the whole thing.
Encoding can be done by “handbrake”
dnf install HandBrake
Very good fo encoding and 100% free.
For editing I used Lightworks a view years back.
There is an opportunity to use it for free.
But you will need to sign up for a user account at least, in order to download it. Don’t remember if there’s a lot of editing capabilities besides of cutting for the free version, website says no.
Edit: Yes, can do Text and Effects and whatnot when subscribing and paying a monthly or yearly fee: https://lwks.com/features/
Lightworks supports 720p Export Only in the free version, it says, nothing beyond 720p: Lightworks - Tech Specs - LWKS - Video Editing Software
But if you want to spend some money, it is a very good program.
Then there are:
