What is a desktop video capture software with high quality compact recording format?

Question

Video capture

Need a free desktop video capture program for personal use.
The essence of the problem:
Very rarely I use some programs. (Quartus, Keil, MPLab, CCS, etc.)
Some very important settings are buried deep in implicit menus, submenus, subsubmenus, subclabs, subbuttons, subfiles.
You have to spend a lot of time looking for a solution to a problem.
I want to record a video so that I can remember everything in 5 minutes.
Need free, compact, fast, convenient.
It is often difficult to find solutions in Google among the garbage cans, and the Internet is not always smooth.

Answer 1

On Windows I use FastStone Capture. No extra questions or notifications.
