VideoPad is a video creation software aimed at a prosumer audience.  It is fairly full-featured (comparable to iMovie) and has Windows, Mac, Android, and iOS versions.  The free version has limited features (e.g., tracks limited to 2 audio and 2 video tracks), but you can still make a pretty versatile project with the free version.  You can download the software here, and you can also access some tutorials about the software with this Getting Started Guide or this Youtube Channel.
