I've had some fun using movavi, I'll admit, but it's a very subpar program without access to a lot of basic features like pitch shifting or distortion and a lot of your ability to edit is made tedious by unnecessary restrictions that don't make any sense, like not being able to change audio effects to more than one piece of video at a time. If you clip a video into segments, you cannot merge them back together. It just all around strikes me as a program made by amateurs.
There's quite a few glitches like if you click to save a video, but change your mind, you have to ctrl+alt+del the program to not save the video, like it's trying to force you to save it for some reason. It's also very laggy but I haven't used too many other video editors to compare it to. When the video lasts more than 3-4 minutes, applying a simple edit like changing the speed or volume of a piece of the video can cause lag for like 5-10 seconds.
Very importantly, movavi has a lot of troubles exporting files as movies so most of the time for larger videos I have to watch the edit in fullscreen and record a screencap, which seems super primitive to me but this is a really shoddily made program with a seemingly nonexistent team behind it, so I would bet my first born they'll never make it export properly.
I think its pretty obvious based by the few overwhelmingly positive reviews I can find about Movavi, that they probably weren't written by actual users of it, but by people trying to sell it. The review I'm replying to is likely fake because of how vague it is; this exact review could apply to any video editor ever and there's no indication that the person that wrote it even knows what they're talking about.
