Motors are the main culprit. What model are they? The motors I got with my Scalu kit were only 0.4A units, as such you have to run them at high current for these motors to avoid skipping steps which generates a lot of motor resonance. I think this is your problem as I can see your b motor belt resonating in the video when the noise happens.

I swapped them for 1.68A units, left the stepper current the same and carried on with much less noise.

How many steps per mm are you using for X and y if it's less than 80 then your not on 1/16th microstepping. More microstepping equals less noise.

Look at the motor mounts, see my things I've made in my signature, I've remixed the motor mounts both the original ones and made some fully adjustable ones which position the motors away from the frame.

Steps per mm are in your marlin configuration.h or by sending m503. It will say M92 X80 Y80 Z80 E300 or something like that.
