I wonder the same. i think it definitely helps. My last heli was the Xaircraft v8 and it was good for a few hours before video really was just giving me a headache. Although using the Xaircraft controller, I am using so many different components now it is hard to say which ones make my video so smooth. but I think the av130 has a huge role in this. If not just keeping the camera steady I think the added mass does it good.
We are in a fortunate situation with most of our heli's where we have an abundance of power to deal with. Unlike that guy trying to make his lawnmower fly we are not harmed by adding wires and circuits as much as we tend to cry about on here.

This is interesting, I was about to post and ask. I think the pitch and roll definitely add to smoothness and if dialed in properly the video even looks like its slowed down. However, the vibration is a totally different thing, I have an Xa x650 v8 with averticalview mount. after playing around with GoPro I almost dialed it in and video is "Ok" not great but the pitch roll compensation was good but you can see some vibration when moving fast maneuvers or wind blowing on multi. This vibes translate to bad rolling shutter ( I am not sure if the term is right) wavy video on my HX9V same mount as with the GoPro. Vibration could be attributed to balanced props, low vibe motor etc.
@IrisAerial, do you have a photo of how you mounted the AV130 on the x650 I am considering to get one. I think on my quad the main contributor of the vibration is the propwash on the gimbal because of how it was designed.

On the issue of video stability, I'm curious as to how important it is to balance props on a multi-rotors. I've seen some threads here discussing techniques of balancing props but couldn't find a discussion regarding how big of an issue it is in general. I would have thought modern manufacturing techniques would basically turn out propeller clones that would be perfectly balanced but, obviously, that's not the case. I understand that every case and every copter is different, but I am very interested in trying to break down the various causes of vibration and how best to attack them. I have an AV130 and my assessment is that its role in reducing vibration is limited to the dampening effect of its components as opposed to servo response. As I read Jffry7's note, he seems to be saying the same thing - the pitch & roll compensation certainly help framing, but the primary vibration that afflicts video performance is at a frequency far too high for servo compensation (at least by the level of servos used in the AV130).

I dont have an x650. I have a custom made hex that is about 850mm motor to motor.

I could be wrong but servos are only meant to compensate what their named for i.e. tilt servo to compensate pitch movement of quad same with the roll. Vibration is a completely different issue, like you said only dampening and balanced motor/prop. However having said that there is a mix to this, when the quad is not stable and oscillates this induces a different type of vibration on the camera mount if its not stiff enough. In my case its when the propwash hits the camera mount it causes vibration making my video wavy. I have the same setup as Marcus G. but his video dont show any vibration even in raw video, maybe a little but post can take it out. The only difference in our setup is the camera mount (an the battery but irrelevant). Maybe the experts can give more light to newbies like me

My Theory was correct, mounting the camera in front with an wider pops will cause turbulence/vibration (propwash). I have been playing around camera mounts for my x650 v8 and not one was usable due to wavy video when taken from Sony HX9V. GoPro was somewhat better but still vibration can be seen. I have mounted the same cam mount so that it will be tuck underneath the center plate away from the propwash and heres what i got
There are still vibration but the video but this is the best I got from the HX9V. This is a raw video not perfect but still some progress. Now I just need to find a way to mount it so that no props will show.

The lower the camera, the less likely you are to see the props. Extend the landing gear a few inches & then you can lower the camera even further. Thats how my cam gimbal works.
