rescramble

Recently I am interested to learn match the scramble (or the rescramble held by redbull if I am not wrong?), however I don't see any tutorials or methods online looks so weird. I wonder if anyone can share any videos or articles, or how to learn about it?

So I was recently introduced to rescramble by J perm's video on the topic, and I tried it on the 4x4 cube, only to have center parities. I was wondering if there is anyway to get around this problem, because I can't figure out how to.
