stabilize jumpy video

What's the best way on Windows to stabilize a jump MP4 phone video?
I have a bunch of short videos for upload to web sites.
But some are jumpy due to the content being outdoors while moving.
What do you use for Windows software to quickly stabilize jumpy videos?
It's not for professional videos so something fast & easy is best.
Googling, I found Gyroflow open sourcware but it's for cameras.

But most of the hits are shills which make believe they're helping you but
in the end they always seem to claim it's too complicated unless you do it
the way they want you to do it - which is never going to be freeware tools.
