Adobe Premiere has very complex functionality so I don't prefer to work with it. Magix is pretty cool software, but it's not professional software and it has a lot of drawbacks. However, I'm surprised that you don't like Movavi. It supports quite a lot of codecs and formats. It seems to me that the problem was in the old version of the software and new versions support more modern codecs. You can update Movavi here . Also, you can try to convert your video online and continue editing it in Movavi.
