Video editing is a pretty big topic. I made a video a few years with LightWorks which was a real bear to operate. Microsoft Movie is no longer easily available on windows 10 so I searched WordPress and someone recommended SHOTCUT.
Shotcut enables you to assemble images and clips or parts of clips onto a timeline just like LightWorks and MS Movie but the user interface is much easier to mange. The timeline contains both audio and video tracks from videos in your playlist.
You can easily create transitions between shots and remove all of the audio from the clips you load and replace it with custom sound if you are so inclined. You can create and manage Titles and text overlays that follow parts of your movie.
I’m still learning to use SHOTCUT but if anyone wants to create a video from some smart phone footage I’ll give it a try. I use AUDACITY, as a digital audio workstation. It lets me create multi track audio and mix tracks down to stereo for publication or to use as a studio audio track with a video.
Both AUDACITY and SHOTCUT are open source and cost only time to download and install.
