Some searching through google, "alternativeto", YouTube, for video and audio editing or recording software, FREEWARE, showed BandiCam, Screencast-o-matic, Audacity, and I've been aware of Windows Movie Maker.
I would like to be able to make audio adjustments and audio changes to a few screencast videos. I do not really undestand Audacity; but tried learning it many years ago. I am absolutely not confident nor comfortable with learning Movie Maker; I am not sure how to handle Bandicam, having tried it briefly many many months ago. I am comfortable with and have used Screencast-o-matic, the free downloadable version, a few times, and it was fairly easy to learn and to use. I would just like to learn and use something a little bit more clever than Screen-cast-o-matic, and to edit or make changes to some video recordings. FREE/FREEWARE wanted.
