Can used Zorin 15?
Shouldn't be a problem.
I already have the live wallpaper. Then put it in the wallpaper folder. when I try to use it it doesn't appear in the settings. What extensions are used? mp4 or another?
It will not appear in settings. You have to point it to the file you made in autostart. When you login it will run.
Ok.
Is there any other way?
You could try Komorebi - BUT, it's buggy and resource hungry and havn't been updated since 2019.
I have tried Komorebi and not had much luck with it. I think your method is much cleaner and easier.
I made a wallpaper that covers both monitors that have spinning fans on it. My only complaint is that they do not seem to cool my computer...
I feel bad for him if he sneezes.
I guess he has no nose 
Any good engine to get live wallpaper on Zorin OS.
