Annoying mid throttle vibrations

Hi everyone!! I finished my first 220mm quadcopter a few weeks ago and I just did my first 5-6 flights.
From the beginning i noticed that it has some strange vibrations at mid throttle. They increase when I fly with more weight (gopro). I thougt that they could be some wrong roll pid setting but after I tried to modify the pids almost nothing changed.

Here you can see what my quad does:
What can it be?

Ps: Don't care about my bad skills and robotic movements...it was only my 2nd acro flight! :)

Most yaw and mid throttle twitching is noise induced from voltage spikes. Flight controllers such as the Lux and Rev6 Naze which use the MPU 6500 gyro chip are especially sensitive, not sure what the Kiss uses. But I'd focus on noise reduction, start out with simple stuff such as are all the screws in your frame tight and are any of your props/motor shafts bent. You stated that your FC is soft-mounted but you could also do the same with the motors. BUT the biggest noise reduction can be had by simply soldering a 1000 uF 35V low ESR capacitor onto the main battery pads. This will also have a nice side-effect of cleaning up any crap in your video feed. I use these ones.

Sorry, i forgot to wright the specs.
I have a martian II frame with an omnibus F4 v2 fc (betaflight), emax 2205s, emax bullet 30A esc and a 1000uF capacitor on the pdb for video noise reduction.
I didn't try to soft mount the fc yet...I'll try this week
Thanks for your help!
 
If your going to soft mount get really good gyro tape not the cheap stuff , any tape they use for RC Helicopters will be best
