Cinelerra *had* the most promise and it’s probably good if you want to run a TV station. However, it’s not creative at all. Simple edits are easy. However, anything else can become a stunt. IMO, Kdenlive has seen the quickest growth. Lives is also doing well. In the next few years we may see those apps grow into the free alternative of Finalcut – but not Cinelerra. It does what it does, and there is no need to change.
Far from the “it just works” dream, this program just does not work. I have a relatively fast i7 laptop with plenty of RAM, but OpenShot slowed my entire system to a crawl as soon as I started to edit some video. Firefox became unresponsive and OpenShot crashed or at least appeared to do so since a crash report window opened but OpenShot did not close.
Pitivi has been around for a few years too. This video editor for Linux is a GNOME application and is designed to fit into the GNOME desktop. (I assume it will work just fine in KDE or XFCE too.) Installing it requires the use of Flatpak, but they give rather easy-to-use instructions on the Pitivi website, and I had no problems at all. Drag-and-drop seems to be well supported, and it first transcodes videos before they can be used, which takes a few minutes or seconds, depending on the size of each. But it appears the videos can still be used during this process.
That was the first video editing software package I bought for making home movies. It was easy to use, intuitive even, although some bits were a bit clunky. After making 20 or so coasters, it turned out to be near impossible to burn DVDs. Going online I discovered that burning DVDs was a common problem that upgrading wouldn’t help so I bought Vegas. Since my goal is primarily making home movies for distribution to a far flung computer illiterate family (and that isn’t even just the octegenarians) this is important.
Vidnami promises that you can “Create Stunning Videos Fast” with their app. You can use Vidnami video creation software to turn articles, blog posts and shorter pieces of content into videos in minutes, or so the creators claim. I’ve spent a lot of money having freelancers create videos for me, so I figured I would give Vidnami a shot.
