Cinelarra is for video producers who need more than OpenShot, and who want a native Linux professional-quality video editor that supports high-resolution audio and video, and advanced features such as hue and saturation, overlays, denoising, compression, normalization, time stretching, realtime effects, nested sequences, color balance, image flipping, text-to-movie, batch render and batch capture, compositing, and much more. Cinelarra has nice integration between audio and video, and makes it easy to control synchronization. Blender and Cinelarra work well together; create your splendid animations in Blender and then integrate them into a movie in Cinelarra.

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.
I have a small favor to ask. More people are reading the nixCraft. Many of you block advertising which is your right, and advertising revenues are not sufficient to cover my operating costs. So you can see why I need to ask for your help. The nixCraft takes a lot of my time and hard work to produce. If everyone who reads nixCraft, who likes it, helps fund it, my future would be more secure. You can donate as little as $1 to support nixCraft:
Content Samurai promises that you can “Create Stunning Videos Fast” with their app. You can use Content Samurai 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 Content Samurai a shot.
