How to make music videos like this…

Hi everyone. First post here.

I have had a search and couldn’t find too much on video to four to the floor electronic music where images and video change to the beat around 126bpm. What do you think the (amazing) McGloughlin Brothers are using when this kicks off at about 3 minutes https://vimeo.com/431672375 ?

Also when lots and lots of images are shown rapidly after each other. Are they just painstakingly using Premier or FCPX, eg: https://www.instagram.com/p/CFZguc9HUDy

Any guidance would be a big help. Thank you
