Re: Filming from an X-trail - problem with rough roads Tried filming from the C5. Unfortunately quite a few of the bumps in the road were transmitted to the cabin, jolting the video. Not sure if its any better than the X-trail. Will test the same roads when I get the X-Trail back on Friday. 235/75 15" wheels may be the answer after all. Cheaper anyway. Also my wife didn't like the C5 much.
Yes I'm pretty keen to make good quality cycling videos for the Tacx trainer. I have an outlet to sell them in Germany. I have one selling at the moment but another (up Mt Wellington) was rejected because it was just too bumpy. I also use them for my own training.
Re: Filming from an X-trail - problem with rough roads I have found a partial solution. Its a fee program which I used to use many years ago called Virtual Dub. It now has a free plugin called DeShaker. You load your video into Virtual Dub (unfortunately it wouldn't load AVCHD, so I used Sony Vegas to render it as a high quality AVI file first). You then load the DeShaker plugin and run it. After the first run you then run the second step. After this you have a video that is free from almost all shakes. The only ones it couldn't cope with are the short sharp jolts, though by manipulating the settings it still may be able to deal with these. The improvement in video stability is very impressive. Much better than the commercial programs.
Re: Filming from an X-trail - problem with rough roads After doing some more research I have found the solutions to my filming problems. The first is to film from the center of the forward roof rack. This places the camera over the center of the car where bumps will be minimized.
The second is to use a CCD video camera instead of a CMOS video camera. Tested my old Panasonic 3 CCD NV-GS400 against my Canon HG20. The Panasonic was much better at handling bumps. It seems that CMOS sensors, found on most cameras these days are particularly bad with bumps and vibrations. Do a seach of CCD vs CMOS with vibrations on You Tube and you will see some really good examples. I'll be getting a 3 CCD HD camera ASAP.
The third is to deflate the tyres. I use 14psi.
The fourth is to use Virtual Dub’s Deshaker. A free program which cam remove most bumps and shakes.
The fifth, if all else fails, buy a gyroscopic stabiliser. They are very expensive but professional photographers all use them these days. Look up Kenyon on the web to find more about them. $2000 USD for small one.
