It is always the situation that you need to record the computer screen of a critical webinar or a live game. In the past, if you wanted to record the screen, you had to install a third-party tool or use the plug-in on your browser. I want to tell you that you don't need to spend a lot of time searching for a recording program or downloading or installing extensions as long as you have a browser and the Internet. You can easily record screen images through an online screen recorder on the RecordCast website. The point is that it is free.

I choose to test it with only the screen. Before recording the screen, choose whether to include sound. The source of the sound can mix and match the microphone with the sound on the system. You also have the choice to not record any sound by selecting "No audio" and clicking "Start Recording." Next is the choice of sharing the screen, which is to choose the screen you want to record. There are three choices for the whole screen in the picture below, the application window and the Chrome tab screen. You can choose the entire screen to try.

The video editor is built with a wide selection of simple fonts and dynamic text. You can preview the effects and apply the one you like to your words.
