Absolutely, OBS and Geforce Experience's recording feature are good bets for screencasting. Similarly, there are some other options like AMD Relive, Windows 10's Game Bar, Mac's QuickTime (you need to download soundflower to grab the internal sound) and desktop screen recording software like RecMaster (what i'm using for some game and video presentation capture). Besides those standalone programs, there are many decent online services and plugins you can rely on for quick recording and instant sharing.
