Peek was created for special occasions when you want to record video from the screen, for example, to easily display the interface capabilities of your apps or display bugs when reporting a bug.
Peek only works with the X11 and is aimed at GNOME 3. Therefore, it should work well in Linux Mint.
To install the application requires the ffmpeg library.
Installation latest version into Linux Mint <=18.2:
sudo add-apt-repository ppa:peek-developers/stable sudo apt update sudo apt install peek
