Question

And so the essence of the matter is this. I stumbled on a youtube channel on the subject of linux. I really want to know through what program the author makes vids, I already asked him a question, the problem is that the last entry in the group was a very long time ago in January, from this I concluded that perhaps he might not answer at all. So I ask how can you achieve this level of quality recording screencasta? It will be interesting for me to read your answers about the software for writing under linux, maybe examples of commands for the terminal, and of course, if linux experts tell me for sure how the author does it, I will be very grateful to you!
