Hilarious!

Lol that's geat! :-D.

By reading the title I thought this thread was about the Movi Gyro steadicam.

Wonderful clip. A steadying device that not only provides breakfast but, eventually, a dinner.

On a technical note, gotta say that I just HATE the "jellocam" effect of CMOS as shown on the motorcycle footage.

"I just HATE the "jellocam" effect of CMOS"

Does CMOS have to be inherently progressive in scanning? Can't the makers take a snapshot of a field or frame as appropriate, and then scan the snapshot? (Analogous to the sample-and-hold module that preceded old-style analogue-to-digital converters.)

I believe the BlackMagic 4K camera has a CMOS sensor with a global shutter. But reading the literature they don't actually say that. Only "global shutter".

Shutter roll is the main reason why I only buy cameras based CCD technology. I rather sacrifice low-light sensitivity to get high image quality during motion. In particular, I'm really glad my cameras (JVC gy-hm750 and gy-hm150) perform well at air shows where quick panning and fast shutter speeds are typical for the task. Also, having thee CCDs eliminates the need for de-Bayering, whose effects I really hate particularly when you need to create sharp luminance or chroma mattes.

Your solution is what happens in a CCD sensor.
There's one CCD per pixel to which the charge on the photodiodes is transferred all at once. Then each CCDs charge is read into an ADC sequentially.

In a CMOS sensor each photodiodes charge is read sequentially directly into the ADC. That takes time hence the rolling shutter effect.
The time taken can be reduced by having more than one ADC but then they all have to be calibrated exactly the same or you can get interesting problems such as one half of the frame not being exactly the same as the other.

One solution that works is to have a real shutter which is an option on Sony's F65. Sony claim their F55 is CMOS and has a global shutter. Someone did ask them "How does that work?" and the answer was "Very well :)" I suspect they've actually dramatically reduced the readout time by having say one ADC per column.

The very high speed cameras oddly enough use CMOS sensors, I have no clue how that works.

A quote from Wiki:

"Since a CMOS video sensor typically captures a row at time within approximately 1/60th or 1/50th of a second (depending on refresh rate) it may result in a "rolling shutter" effect, where the image is skewed (tilted to the left or right, depending on the direction of camera or subject movement). ... A frame-transfer CCD sensor does not have this problem, instead capturing the entire image at once into a frame store."

I guess that I am asking why makers don't implement a frame store with CMOS sensors as well.

Panasonic now uses MOS sensors in the Prosumer and Pro lines. It renders colors nearly as good as FFT and FIT CCD chips, uses less power, has better sensitivity to low light sixe-for-size, and is fairly clean with little noise. Another benefit of it is EXCELLENT Image stabilization. I think the CMOS and CCD have limited days.
