What software is a good replacement for Windows Movie Maker?

   Hi. There are also a large number of linux distros that are designed specifically for audio & video productions.

MAGIX - Vegas Pro 17

"Hitfilm Express"

The free version is very capable and can do most things you are likely to need.

They sell ad-on to enable extra features but I've never needed any.

The only problem I have had is with some oddball MP4 files that did not conform to the MP4 spec (an invalid audio format) - I ran them through handbrake to change that to fit the MP4 AAC standard and then hitfilm imported them OK.

Minecraft Movie Maker

I downloaded a free copy of VLC for playing any movie or video file. It can play anything.

Adobe Premiere Pro but it's about $240. I have to admit Windows Movie Maker was not bad for free.

Windows 10 has Windows Photos.  You can Edit with it.
