Just checked your video!
Sounds like it was quite wind that day! So a little bit of movement in PH is possible for that she of quad.
Do you have a log file of this flight? Looking at the log and the video is most useful.
The 'rapid movement' are either due to vibrations (you can see it from the log) or too high PIDs (compare with the shaking of my quad when on 3S; PIDs were to hight for 3S use)

Yes weather was windy, but this vertical movements was not from wind.
I broke SD card slot when installed N4 expander and I have no possibility to collect logs
Propellers was balanced with du dro balancer. They are not badly balanced, but vibrations exists. I can increase LPF factor in AQ for decrease noise from motors/props?

For the first - are your props and motors balanced ?

Props are balanced by hands with . Motors are factory balanced.

for more you must show logs

How to get logs without SD card?
