I've been talking about recommending Snagit from the folks over at Techsmith for many years. I use it daily, and it's an essential app in my toolbox that I use for my work at Stardock and any other projects I might be working on. They are also from Michigan, and I've had the pleasure of interacting with them for a while as well, so I was happy to see they released a new version of Snagit for both PC and Mac today.
Among the variety of new features, it has an updated user interface, better capture experience, video trimming, and more.
They offer a free trial to check out the new version, and if you are a previous owner you can upgrade for half the cost.
