Finally some good footage from the HX9V


I was plagued with jello effect from the Sony HX9V. I think I finally got it under control:

Wow that looks great, especially for a HX9V. Did you shoot 60P?

What did you use for vibration isolation?

I've been wanting to get the Sony HX9V and was told it's an awesome camera but maybe not so good for aerial photography on a hexacopter.

I bought a Samsung H300 camcorder and it was horrible, I think I might try the the Sony.

these are the ones I ordered. Should be here next week.
http://www.vibrationmounts.com/Store...=Products7.htm
$10 a piece

I only ordered 4 as that is what Askman's modified plates use....

they seem to work well, ill post results when i get them.



although I do not have a HX9v I will throw my gopro on it as well as nex-5n


the zeal tape gel is amazing and has completely isolated my CCD FPV camera from any vibrations, super simple to use and amazing stuff!

They do work very well. Don't smash them together too much though.

Those gel bushing will work great for both the GoPro and the NEX 5N.

Zeal tape is wonderful stuff. I use a lot of that from my single main rotor helicopter days.

Nice to see some jello-free filming!

I got myself a HX9V but got disappointed as it showed heavy jello and vibrations. My old Canon IXUS 70 doesnít show any sign of vibrations with the same setup.
I have spent pretty long time to balance my props and I canít get them any better than they are.

So I have tried to isolate the vibrations from the camera mount. This is my latest attempt with adhesive foam and rubber grommets. It has got better, but there are still way too much vibrations. Now I donít know what else to try.
- Any ideas?

Maybe the camera tray should be suspended with more than two attachment points?

you need really soft silicon gel grommet like ones seismic used. soft silicon foam may work, but most foam rubber is too springy to be a good isolator.

zeal gyro tape.... i think you will be amazed..... there will literally be 0 vibrations getting to your camera.


I flew my Y-6 with APCs that had some really hard prop strikes and had chunks missing and my little lights CCD FPV camera had 0 vibrations. I was simple amazed!

You have a couple of issues with your current setup.

1) The foam may be isolating vibration but it really depends on the size of your hole where the bolt goes through. If the hole is not large enough the bolt may be touching and transmitter the vibration.

2) With only two attachment points plus isolation you get a lot of fore/aft movement. The HX9V has an in-camera image stabilization. If there is a lot of movement the image stabilization will not be able to cope and you wind up having jello effect.

My suggestion is to make some sort of grommets by stacking foam rings with different diameters.

Secondly try using softer materials like yoga pad.

Thirdly you need to spread out the vibration isolation attachment points as far as possible to reduce unwanted movement.

Thanks for your suggestions!

I tried, a different approach, last night to sandwich the motor arms with foam to isolate the arms from the frame. This worked pretty good as it sounds a bit quieter and I can't feel any vibrations on the frame. But - there was almost no improvement on the camera!
Also, this prevents the folding mechanism of the arms so I will remove this.

It is frustrating because compared to my other camera this one seems very sensitive!

The hole in the plywood should be large enough so the nut will not touch the wood, but the gap is very small and could be larger.

I will try to create three attachment points for the camera to reduce any possible fore/aft movement and maybe try to create a larger "membrane" of foam, like a x-large grommet to soften the mount.
