Screen capture apps record what's happening on your screen, including the movement of your cursor, so you can deliver instructions, describe problems, or share knowledge. Writing out descriptions of such things takes significantly longer than just showing someone your screen, but you're usually not standing next to the person or people who need to see your screen. Video capture apps solve that problem.

Following up on the status

as to best screen recorder I recommend Joyoshare VidiKit, which allows you record your screen, specific web, audio, webcam and gameplay, with no lag and high quality, what's more, it uses easily, friendly for new beginners！

Camtasia and OBS are the best.
