Movie Maker was simply an unbeatable program for simple video editing. When I was looking for its successor, the OpenShot Video Editor worked best for me, but it has a typically ugly user interface.
In Windows 10, there is an app called Photos, which is primarily used for viewing images, including those stored on OneDrive. The program Video Editor is incorporated into it a bit awkwardly.
However, it is great for quick video editing. You can add a title, insert videos, possibly cut them a bit, choose a pre-prepared song, and that’s it. Of course, you can also add some 3D effects - explosions, rain, etc., including the ability to anchor them to a certain point on the screen. Everything is beautifully simple and the program has a nice modern look.
The only thing that bothers me about it is the absence of a timeline for adding music. It’s simply the price of simplicity.
I add videos to my YouTube channel quite often, and lately they have been “edited” in this program.
