Can you use something on Linux? Or must it be on Windows? I'm not super knowledgeable with video editors, but I have messed around with them from time to time.
On Windows, yeah, I miss Windows Movie Maker. Free software that comes bundled with the OS and is adequate is always a good thing. But since MS decided to axe it, I went with Adobe Premiere Elements. I don't want an expensive subscription for the full version of Premiere, since (at this time) I only use it once in a while. With Premeire Elements, you pay a flat fee upfront and then you own it for a Lifetime, although you only get updates for a year. I'm fine with that though, for the light amount of editing I do on a blue moon. It's watered down from the full version of Premiere, but to be honest I don't really know what I'm missing LOL. It has a couple of easy modes, but then it has a full non-linear mode.
It's usually $100 by itself, although there are sales occassionally (that's how I got mine). And if you're interested, you can get it bundled with Photoshop Elements for a discount, $150 I believe. Also, I think there might be student discounts on it. But as for Photoshop Elements, unfortunately I learned only after purchasing it that it's gimped way too much for me. But luckily the subscription for the full version of Photoshop is affordable, and I use it enough to justify having it.
As for free Windows stuff, I'd be interested to learn of anything current. The last time I used something free on Windows was Lightworks.
https://en.wikipedia.org/wiki/LightworksIt seems like it's powerful, but it will take a lot of time to learn how to use it. At least, that was my experience with it. Also, the free version is gimped in how you can export a project. IIRC, when I was using it you were only able to export to YouTube. I just read briefly on Wikipedia that you can export to HDD as well. Not sure if that's a new feature for the free version, but at least there's that. You still cannot create a DVD or BD, so you will need additional mastering software if that's what you need (Windows also use to have this!). DVD/BD mastering is also something Premiere Elements can do, which is another reason I went with it.
If you can use Linux though, definitely check out the repository on whatever distro you're using. A while back I needed something real quick when I had Mint on my laptop, and I found 2 or 3 that looked really promising. I installed a couple of them. I went with the one I that had a GUI I could most easily navigate without having to resort to a Youtube video to figure something out. I just needed to edit a few things real fast, but it looked like it would have worked at least as well as Premiere Elements has for me. Sorry, I don't recall the name of it. But just check the repository for non linear video editors. I bet there will be a few of them, just check them all out and go with whatever one you feel most comfortable with.
