If you’re looking for an alternative to Adobe Premier, HitFilm 3 Express is Free and has loads of features. You can download it at this site.
It works on both Windows and Mac.
Videomaker has a nice review if you want to get into the details of the Pro version.
HitFilm has tutorials at: https://hitfilm.com/video-tutorials#/
I also noticed that Lynda.com has six hours of tutorials, but of course you have to subscribe.
If you want the Pro version, it costs $299 which is just about the price you’d pay to for one year of Adobe Premier. Amazon has it for a slightly cheaper price.
