  • Desktop Option: It is an experimental option which you can use to record desktop screen with any preset size. But first you need to access ‘Chrome flags’ page on your Chrome browser and have to enable Screen capture support in getUser Media() option. You can access and enable this option using the address visible in screenshot below. If you think, it will make some unexpected changes to your browser, then I won’t recommend it to you. But during testing, it worked completely fine for me.

After enabling this option, you need to use Relaunch now button that will be available at the bottom of that page. Now, this screen video recorder will be able to record your desktop screen. Simply click its extension icon, set Desktop option, adjust screen size, frame rate, etc. and click on Start Recording button.
