While it is simple, it lacks many of the more advanced features found in commercial video editing software, which shouldn't matter to the majority of users of this product. Another issue is that Microsoft has virtually dropped support for this, and is potentially looking to release a newer version at some point. Competitors on the market such as iMovie have continued to be supported with newer features such as 4K support.
Free video editing software often comes with legal and technical limitations, however. Some widely used codecs require licensing fees on the part of the software maker, meaning they can't offer free software that can handle these standard file formats. That said, the impressive open-source Shotcut does a lot of the same things that the paid applications in this roundup do, including things like chroma-keying and picture-in-picture. Shotcut is completely open-source and free, while another free option, Lightworks has paid options that remove a 720p output resolution limit. Note also that both Shotcut and Lightworks run on Linux as well as Windows and Mac.
This program checks in at about 26MB, which isn't gigantic, but is still relatively large. For that, you'll get a program that is a dead ringer for professional editing programs. It has the same sort of timeline editing style that lets you combine multiple cuts, add transitions, and render them into a complete project. As such, it isn't very easy to use unless you really know what you're doing. Few things are labeled or intuitive, and all of your tools are spread out across multiple menus. If you can find the features, there are plenty of ways to cut, reshape, and modify your video's picture and audio, though. You can even kick the quality up to 30 FPS and 1080p HD. VSDC Free Video Editor supports just about every video format you can think of, so you'll have no problem turning any video into a project.
The free HitFilm Express 9 has a quirky but appealing interface and plenty of powerful features, including a new layout panel and better export tools. An optional Starter Pack ($9.99) adds even more editing options. It's good for prosumers and enthusiasts with cross-platform editing and compositing abilities, tracking options, 2D and 3D effects, speed controls, audio tools and an arsenal of instructional videos.

First, I already kind of mentioned, but the grid view inside the viewfinder, they should give you options and the "thirds" grid should definitely be an option as the "rule of thirds" is a very good guide to follow in the absence of a clearer way to frame a photo. I hope in their future cameras they will have this. Or if somehow a firmware upgrade could add this, I'm not sure how hard-wired this grid is in the viewfinder if moving the lines would even be possible through software...
The T#i line is what they call a "pro-sumer" line, which is basically between a consumer line camera like a very basic DSLR and a professional DSLR camera, thus the term "pro-sumer." Typically what this meant is an DSLR with an APS-C sized sensor, decent resolution, and some hand-me-down professional features of pro-grade cameras from a few years ago. For this reason, sometimes it's not worth upgrading from one of these cameras to the next until at least a few generations have past (meaning if you have a T5i, it's not really a giant leap forward to upgrade to a T6i). However, the T7i is somewhat different. When I was doing research on what features it has and what it is missing compared to the pro-grade DSLRs that are considered "current" right now, I was surprised to find very little. The main differences really is that the pro-grade cameras have the LCD display on the top that would display all of your relevant camera settings, and then a few of them would also sport a full-frame sensor. Other than that, the differences are very minor. Something like maybe 1 or 2 frames less in burst mode or something like that. Nothing that would really jump out at you and make you regret not stepping up to the professional grade equivalent (Think it would be the 77D?). It actually has pretty much all of the big features of even their current pro-grade DSLRs, making the T7i probably one of the best prosumer DSLRs to buy.
