In terms of usability, Camtasia should be among the top choices due to how beginner-friendly it is. But, also due to its simplicity, not too many professional creators will find Camtasia Studio appealing. If you’re only starting to learn the basics of video editing, this app is perfect for that. It’s got a nice interface, intuitive controls, and useful tutorials. Those are everything you need for an easy beginning. 
Using Adobe Spark as a free video maker simply couldn’t be easier. After selecting the “Video” option from the main menu, you’ll be taken to a title screen — where you can give your video project a title. Enter some text, or skip this stage and head straight to the design interface. Don’t worry if you want to change the title later, as you can make unlimited changes to text. You then get the opportunity to choose a video template or start the design process from scratch.
This Camtasia Studio download uses your CPU for its rendering process, so that relies heavily on your graphics card. It doesn’t work as well as NVENC encoding. The older your video card is, the longer it will take. For devices with less than 6GB of RAM, using CS can slow down your other applications. The initial startup may take a while, depending on your computer’s capacity. Make sure you uncheck the reboot box when prompted by the app. It may complicate your drivers, but this is different for every user.
PC World noted that "Camtasia has evolved from being the go-to program for software demonstrators to a full-featured education/information video tool" from this 4 1/2 star review. An earlier 2005 review is still relevant, which states that, though "powerful," Camtasia can be "a little overwhelming at the start" to new users, though the learning curve is easily manageable.[5][6][7]
In Camtasia editor, multimedia objects of various formats can be imported into the clip library and arrange them in time order and stacked tracks using the timeline form of user controls. Overlays of various types may be added, including user-defined settings, such as when and how to display the cursor and pan-and-zoom effects such as the Ken Burns effect. Camtasia for Windows v8 and Camtasia for Mac v2 offer options to enhance sections of the recorded screen to draw attention via a cursor or drawn-in pointer to highlight section(s) of the screen or to better illustrate the actions of the presenter on the screen. Another feature is the ability to save media clips within the library tab, keeping a user from having to repeatedly import commonly-used media clips/files.
Though university I graduated from (and one my daughter currently attends) have limited academic licenses available, I chose to purchase an indvidual pro license that I could use for my personal and professional use in 2011. I am glad I did! At the time I purchased Camtasia Studio 7 (CS7), but at a time when Camtasia Studio 8 was being previewed and was a no cost upgrade. There have been some growing pains with Camtasia Studio 8 (CS8), but the current 8.2 release seems to have stabilized and all major features I seek now have more function and are as fast or faster to render as the old reliable CS7.
