I currently use Camtasia extensively for work, and predominately record/edit on a Mac, however we're starting to pick up contractors that work on PC as well, and after playing around with Camtasia for PC, I noticed that the "Mask" effect that can be found in the Visual Effects bin on Camtasia for Mac isn't there for PC. This is an incredibly powerful tool for our workflow and it's surprising it's only included on the Mac version! Perhaps I'm missing it, or it's in a different place, but for the life of me I can't seem to find it!
It's incredibly frustrating and annoying to find that Camtasia has not added the "masking" feature found in its MAC version to their PC version. Camtasia, you are being incredibly tone-deaf and, might I say, arrogant to be completely ignoring this request from so many users out there. Just do a quick google on the net and you will find that people need and want this feature. Here's some unpaid advice: It will make you more money if you add this feature.
