Hello all. I work freelance for FSN Detroit and I run their Steadicam Flyer. We got the rig about 8 months ago. I used it very extensively for 5 months straight on our CCHA All Access show. We have been using it a lot for Red Wings wraps and now starting to do Tigers shoots now that baseball is underway. On top of that they are having me do many other things with it.

My question is, lately I have been having some "vibration" issues depending how I am walking. The vibration is coming from, what I think is, the Camera vibrating up and down if I move a certain way. I use a JVC GY-HD250U HD Camera on the rig. I am not really sure where this issue is coming from. The Flyer plate is screwed in nice and tight on the bottom of the camera where the only hole is.....

Here is the camera. http://pro.jvc.com/p...p;feature_id=03

the only spot to screw the plate on is just right of the "on/off" switch, obviously under the camera. I try to center the plate up to that point.

Any ideas or suggestions?

Chad--

Two things are apparently working against you with this setup.

One, try shoes that have more absorbtion in the footbeds and soles. All vibration is coming from you.

Second, try and loosen your grip on the post and the arm/yoke. Because you have a smaller rig and lighter camera, your grip and touch must be adjusted for the lighter mass you are flying. The smaller camera and sled combination is exponentially harder to finesse than a large rig which naturally has more inertia to overcome tighter and more energetic grip.

This is the hard part; figure out just how little you can hang on and still execute the shots as required.

Good luck!

Best,

Brant

I have experienced a vibration problem with a flyer. In my case it was coming from play that had developed between the gimbal ring and the yoke. It was a rented rig so I didn't see the fix through but I believe the fix was to shim the bolts that hold the yoke to the gimbal ring. If you are having the same problem you'll be able to tell by holding the yoke and the gimbal and pushing and pulling horizontally/side to side against the yoke. The movement is small but it really translates into the shot.

Chad,
are you screwing the camera directly to the Flyer plate or are you using the Sony mount shown in the picture you attached?

Because if you are just using the screw up front it could be that the back of the camera is having a prblems staying put and with every step you get a slight bit of movement translating into vibration . . .

Of course all of our remedies are all speculation since we cannot actually see your set up or feel what you are feeling while flying your rig

Do you have any picts of your set up and maybe we can help you little more

All ther best

Yes I have been attaching the plate right to the camera, where there is only one screw hole. Here is a sample picture.

Not the greatest shots to show my setup up close but you should be able to get the basic idea. I have tried using a plate (tripod) attached to the camera then screwing on the dovetail but that seems to be making the rig too top heavy and really hard to fly.

Hey Chad,

The final picture in your list there is very telling (this one). The camera is teetering atop that small plate that is in between the camera and your dovetail. I'm not sure what that is. I've flown that camera a few times and I don't recall dealing with something like that. You should definitely try to mount your dovetail directly to the camera. The more surface area in contact with the camera, the more stable the mounting will be.

That is the part for mounting a tripod plate. I guess I was unaware that I should have that off.

Edit..

I am off to shot Detroit Red Wings Weekly Wraps. I will make a few adjustments and take that part off the bottom of the camera. I will let you all how it goes. Thanks for all the replies!!!

Chad

Definitely. I almost guarantee that's your problem. There's so much leverage on either side of that plate, it would vibrate no matter how much you tighten it down.

Hey Chad,
As Afton and I suspected that seems to be where your vibration is coming from, doesn't that camera come with the sony plate attachment so that the camera is fixed at the front and the back?

Let us know if that solves the problem

I will get in contact with Fox to see if we can get one ordered for that JVC because to my knowledge whoever opened the box when they first got it 9 months ago, missed placed it (AKA lost it). I can see how that would help tremendously.

Using the suggestions you all have given me, tonight went very well. I had to train myself to fly more and not grip it as much. With the shoots I do it is really really easy to do that. With that said, I made a conscience effort to do what I was trained and had practiced over and over :lol:, and took off that plate so their was direct contact with the camera.

Thanks again all for the suggestions. Now I just need to get that plate and I should be even more in the clear.

If you put the rig on, and shake it a little, can you see where the play is?
I had a similar issue with Sachtler's Artemis Pro. I tracked the movement down past the camera to the block which controls the fore/aft side/side adjustments which was begining to loosen up a tiny bit. On camera it looked as if the lense or camera was a little loose and only if I moved quickly.
The allen screws were accessed by removing the dovetail plate. I dont know how the flyer is built, but I would double check every screw and bolt that you can see and cannot see.

I have used the JVC with that same tripod mounting kit and have never had a problem. It is small and looks cheap, but seems pretty solid.

Well it looks like I might of found my issue. The dock where you slide the camera on to, where you control the fore and after and side to side is loose. I can hold on to each end, move it up and down and feel it being loose.

I looked at every single allen wrench hole that I could find and they were all tight. It seems to be the part of that docking unit that is exactly in the middle of the part. Anyone have this issue? I'm hoping this isn't something that would need to be shipped in.

edit..so yes it looks like that center part on the bottom of the docking bay but I can't find anyway to tighten it up.

In my opinion, this is where your vibration is coming from... one thing I should have said before: dont over tighten the bolts, make sure you have the correct amount of tourqe.

I dont know much about how the Flyer is built though-
anyone have an idea which screw might be loose??

Yeah unfortunetly I really have no clue where to tighten it up. All visable screw/allen wrench holes are tight.

Chad,
I had an issue with the stage on my archer. One of the screws inside the stage was loose. I live very close to Tiffen, so I just took it over there and they fixed it on the spot. I would call them to see how to resolve it. Maybe you can do it yourself.
