If you want a very simple screen recording app that gives you basic features without burdening you with bells and whistles, that would be Camstudio. This completely free tool allows you to easily record your computer screen with the advantage of webcam recording and, similar to ScreenRec, audio recording from not just a mic but your computer audio as well.
Camtasia studio is currently only available for the Microsoft Windows platform and can be processor intensive when working with recordings. The user is able to capture video of anything on their computer screen (microphone and webcam input as well), and then edit and produce high-quality clips in many different file formats with a smart, quick to learn, and feature-rich interface.
In order to change the filename for your recordings, you need to complete this step BEFORE you create the recording. Otherwise, you will need to rename your files in the folder and THEN import them into Camtasia studio for editing.
