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.
Tech support and documentation: One of the big distinctions between paid and free software is the level of documentation and tech support; paid software has more-explicit and -detailed documentation and guides than the free versions. That said, many software packages post instructional videos of the most popular features to YouTube, and more-complex free packages may offer extensive documentation.
Adding and arranging: When you're ready to make a movie, your first step will be to choose what type of files to add. Options include Video, Audio, Image, Icon, and Lyric. You can add any and all of these to the same project and then move them around on the Timeline until you have them where you want them. And if you're new to this type of program, there's a convenient Movie Wizard to guide you through the process.
The second big draw is communication. The app creates a unified inbox for comments on Facebook and Instagram and messages from Messenger, so that you don’t have to bounce between different apps in order to respond to people. The app doesn’t seem to cover every possible messaging vector inside of Facebook’s services, but it sounds like a handy start. <<
