This is an excellent question, and it has a simple and short answer: I make and edit videos with it, so that I can sell them and earn money. My industry is the freelance world for music and video, thus, if there´s software that allows me to make and edit videos quickly, then this software will be one of the main tools for my business, and this is the reason why Movie Maker is a vital piece for my business that allows me to handle most of my video needs. 

Like iMovie, Movie Maker uses a simplified version of the standard video editor timeline, with clips represented by "long thumbnails." The first frame is shown at full contrast, while the following ones are faded, in a distinction between this look and iMovie's. The thumbnail tracks optionally show you the audio waveforms along the bottom, so you can see where the loud and quiet parts of your video lay. You get five size choices for the thumbs, which is probably enough, and a zoom control at the bottom lets you stretch out these clip representations. You can trim or split clips using the cursor insertion point combined with edit buttons. It's quite easy once you get used to the unique editing system used by the app: you click at a point in your clip, and can then drag the resulting insertion line around the timeline.
The only advantage of Windows Movie Maker over Filmora is that Windows Movie Maker is free. Though you need to pay for Filmora, the available features make it really worth the money. With all of these features, and many more, it is quite easy to see why Wondershare Filmora has taken over as the new No. 1 video editing software choice. Why don't give it a shot and download it now?

The next advantage is something I already touched on earlier. The size and bulk. These prosumer line cameras are typically much smaller and lighter than their pro-grade cousins. However, I am now completely spoiled by USM lenses (specifically their new nano-USM system), and they are unfortunately bulkier than the "kit lenses" that typically come with these cameras. But overall even with the bulkier lenses, it'll still be much easier to move around with the T7i than with a 5D or a 1D...
This video editor gives you tons of control and editing power, but you'll have to know how to use it. The program could use a manual to help novice users comb through all of the features. Without that, VSDC Free Video Editor will take a lot of experimenting or previous editing know-how to figure out. It's worth spending plenty of time with, though.

We combined a text opener with five clips linked by a cross-fade-type transition into a 2.5-minute video shot at 60 frames per second, and rendered the projects to the MPEG-4 format at 720p. We timed rendering at both 60 fps and 30 fps. We adjusted settings to take advantage of hardware acceleration for all tests whenever possible, setting them in either the preferences or the rendering controls for the best speeds. Apple’s iMovie, the lone Mac-only app, is not included in the timed comparisons.
