Vehicle Mount Stabilization Problems

So I'm having a helluva time here-I would love to hear of something that works to lock down the elements in my V1U. I could use the Z5 in the box I've constructed, feeding HDMI out to the PIX220, but I'd like to reserve the Z5 since it is great for stereo sound, for handheld work, and the FS700 for those special moments, also handheld and tripod-based.

The Hero 3 will cover the rear view.

This older video of mine, made using Sony Handycams, is the level of stability I'm going for:

If nothing else, watch the END!

Problem is that the V1 seems SUPER susceptible to road bumps/vibration, even on smooth asphalt, and the glory shots on this trip are mostly on rough backroads.

I've tried isolating the camera from the box, isolating the box from the vehicle, having both strapped down hard, and every combination.

Using Steadishot in Hard mode helps, but not good enough.

Besides the VW trip, this is also a cool setup for grabbing rolling POV shots for stock - I have sold many of these shots taken last year with the same rig, although using the Z5.

Does anyone know how, without spending too much dough, to eliminate the internal vibration of the lens elements?

Thanks!

Oh, and the clock is ticking: Trip Launch is on Wednesday!

I just came back from a 4x4 trip in the desert. The vehicle had a handle bar in front of the passenger seat. it was a toyota, an 80's model.

I used bungee cords to strap the tripod to the handlebar. I put the 3 feet all the way to the floor. I mounted the camera inside the vehicle and rode in the passenger seat. the handlebar was situated where the glove compartment is, for the passenger to hold during a rough ride.

when driving, I pulled back on the tripod so it wasn't touching the handlebar, and the bungee cord absorbed the shock, and I ended up with great video. this was driving on beaches, in the desert, through mud, all sorts of bumpiness, only 1% was flat driving, in an old vehicle with no tread on the tires and dead shocks.

and I should clarify this was not on a paved surface, it was extreme off road driving

go pro should do well on a car, I never had trouble.

Great video! Like Dave said I also use a bungee sometimes to help smooth the bumps. I've talked with GoPro many times. They're secret is film in 720 HD 60fps and then slow it down to give impression of less "bumps". With he Black you can shoot even faster. Premier Pro CS6 does a real good job on Warp Stabilizer to also help smooth movement.

Thanks. For the most part, GoPro and interior shots have always worked pretty well. Our old VW's have an "Oh Crap!" handle as well, and I also have a tripod mounted behind the bench seat so I can reach back and operate it if need be for pretty cool two-shot forward-facing perspectives. However, the upper camera has been giving me grief. Maybe I should go back to the DV cams! But hey, I sold another one of those clips from that position today....

I guess I'll stick the Z5 up there instead of the V1 and have to rely on the H4n for audio (which is a pain, because this trip is fast-paced, and the Zoom boots SLOW....

If I could just put some of that duct seal stuff around the elements, I think it would work...hehe...
