For example with Camtasia, you can click 1 button and have your desktop + audio + optional webcam all being recorded to your video project, and then you can hop in and edit it with a bunch of great tools and presets. This includes complex animations and tooltips with doing nothing more than dragging around a few sliders.
Basically you can get up and going with an excellent work flow as 1 single person who isn't a video editing god.
Where does Shotcut stand compared to that?
At this point price isn't an issue for people in a position to create videos. It's all about how fast it is to go from an empty folder to a high production quality video.
Camtasia is one of the only reasons why I run Windows so if your project can solve all of those problems, that would be an incredible feat since Camtasia seems to have no intent on supporting anything but Mac / Windows.
Also if it helps gauge the comparison I have tried kdenlive about 6 months ago and compared to Camtasia I would rate kdenlive a 0.001 and Camtasia a 9.5 on the sole task of "quickly create a nice looking screencast".
