Rubber coin... brought to you by... Nikon... who should NOT have insulted us with video THIS bad.

[babnbub]

hey Mike

this video was not produced through a Nikon, but a Sony video camera. lots of professional video cameras have rolling shutter these days, but yeah I wouldn't buy the D90 hoping to get good video, but thats not why you would buy that type of camera anyway!

Thanks for the reply. I have a Sony HVRV1U (HDV on miniDV tape, not AVCHD on card) at work which is CMOS based and it doesn't seem to show rolling shutter effect. I'll be interested to see how this generation of prosumer cams (esp the Canon HF S10) shape up in 2009. At least now I know I can test it in-store with a 20 cent coin :-)

Martin, this effect was done on Sony HVR Z7p with CMOS sensors, same thing recorded to tape. you will be able to replicate this effect on your camera also. this effect has been produced by using very fast shutter speed anad rolling shutter, I believe any camera with rolling shutter will be able to produce this effect. what are you wanting to record with your camera?, send me a private message if you want

Is this effect evident on playback in the camera, or perhaps if the camera was directly connected to a screen, or do you have to import the files into editing software in order to see it. I'm asking this so I can check cameras in the shop for this effect. The new Canon's look good, but I'm concerned about their CMOSs.

Cheers. Martin.

Martin, the effect is seen through the viewfinder and on the camera's screen, lots of people are saying bad things about the cmos sensors, but lots of pro's are using them. lots of vid's have been put on youtube of the D90 in video mode and how great the effect is on that camera but if you buy a good video camera the rolling shutter effect is not as extreme, give john bowring a call from lemac australia to talk about it, he is an expert in this stuff and is happy to discuss

DANG!

What's the music?

The problem with most camera's is not just the wobble effect of CMOS chips.I find that if manufacturers want us to buy HD cameras .Then 1/3 inch sensors with less than 2.2 million pixels doesen't cut it.Also massive compression or long GOP like HDV severly hinder the full potential.Every camera I test has either a poor performing chip(grainy picture or needs way to much light or just to contrasty)Then there are the cameras that record HD footage on to a mini dv cassette

which is just stupid.

Camera companies must have released this current shit generation of CMOS cameras to finance the next generation which hopefully process quickly enough to eliminate the rolling shutter.

I understand you tried to maximize the effect on purpose and it looks cool.

[cozmogeek]

Yeah it is unfortunate. I haven't been able to get any good video from my HV20 in my car. I'm using a suction cup mount that would be awesome if it wasn't for the rolling shutter. Do you think having some kind of padded foam surround so it isn't rigidly attached would make any difference?

[dinoalberini]

Exellent demonstration of rolling shutter issue, it' s not always a bad thing ;)

[formaset]

Besides rolling shutter there is one more issue about CMOS that looks like a jell-o effect when the CMOS is mounted to anything that vibrates. Check out my video "CMOS rolling shutter" It shows cams mounted to a motorcycle. Check it out.

A Sony? I'm shocked! Which one?

I wonder if the Canon HF10/100 has the same problem.
