Re: Filming from an X-trail - problem with rough roads


The rain held off so I just tested the home made CineSaddle. Unfortunately the video was worse with it than without. Too much vibration every time a slight bump came along. Without the CineSaddle, when attached firmly to the car via the roofrack or suction cups the jolts come and go without the vibration as the mass of the car to dampen the vibration.

Back to the drawing board!

 Maybe those bigger tyres are the answer. Having an extra 5cm of air to soften the blows, in combination with 14psi pressure looks the best candidate so far.

Re:


In my truck I found out that having your tyre pressure high takes the bounce out of your wheels/tyres and the shocks dampen the vibration better as they arent fighting the bounce.

Taking 5 cm of profile off our T31 tyres didnt make a huge difference to the vibration in our ride, it just feels harder when hitting the bigger bumps so I would try before buying the tyres if there is no other reason to purchase them.

Re: Filming from an X-trail - problem with rough roads


Tried filming on the weekend, one camera on the bonnet and one on the roof. The one on the bonnet was very bad with lots of jolts. The one on the roof was much much better. I use suction cups to hold the cameras on.

I've read up on CineSaddles and it seems that I may have packed my homemade version too tightly with bean bag balls. I've taken some out and will try again. Only trouble is that mt X-trail is in the panel beaters for 2 1/2 weeks now, getting a total re-spray. Will have to try it on my wife's Getz. Will attach the camera to a brick to give it more mass

Re: Filming from an X-trail - problem with rough roads


Both of my cameras have optical image stabilizers and neither can cope with the very short time span of the jolts. I doubt whether any consumer camera's optical image stabiliser could cope. I think that the answer is to attach the camera firmly to the car. Any attempt to float the camera has resulted in vibration that is worse than the original jolts.

I think the answer is larger aspect tyres at low pressure. My tests have certainly showed that reducing tyre pressure makes a huge improvement. It makes sense that the more air cushioning, the softer the ride. I'm interested in 15" wheels and 235/75 tyres. Posts in the oversize tyres section indicate that these will fit without rubbing.

I'm also interested in adjustable air shock absorbers. Does anyone have any experience with these in terms of making a softer ride?

Re: Filming from an X-trail - problem with rough roads


Watching Top Gear the other day - in England, TV channels used old Citroens to mount thier cameras on for filming Horse Races by driving on the side track alongside the horses; nothing else was as smooth as the Citroen's Oleo-Pneumatic self leveling, 3 height selectable suspension.

Re:


They used to use the big F100 Ambulance vans.
They couldn't have used a more firm vehicle. So it had to be in the camera which used to be mounted on the roof.
I'm not a punter and that was a few years ago that I had noticed them driving around on the inside track.
Probably updated with new technology, like a F250 emoticon

Do you mean the suspension or the colour scheme? emoticon

Re: Filming from an X-trail - problem with rough roads


Will be looking at a Citroen C5 tomorrow with the view to swapping my wifes Getz with one. They have Hydractive 3 Pneumatic Suspension which might be the answer to filming on southern Tassies bumpy roads.
Spoke to Pedders suspension about air shocks for the X-trail and they said that nothing was available. Hence I'm looking at going down the Citreon path.

Geez Barry,
You must be keen about this filming thing if you are going to get a car for it.
