Going for Pinnacle Studio 22 is well worth considering if you've never edited video before and want to delve in for the first time. The pricing is below the average of those above and you can always bail out if you find within the first 30 days that it's just not for you.
But honestly, we'd be surprised if you need to. For in the region of $60/£60, you get more than 1,500 effects, titles, and templates, 6-track HD video editing, handy colouring tools, a dedicated stop motion feature, time remapping and much more. And most features are an absolute doddle to use. So it feels like a genuine step up from free options, without splashing stupid money.
Of course it doesn't have the full suite of features that some others in this list offer, that's not what Studio 22 is all about. And if you try and like the Pinnacle interface and tools, you can always upgrade to one of the company's more comprehensive packages.
