Definitely. :-))

General question.

Wouldn't 4:2:0 = 6 bit 4:2:2 = 8 bit 4:4:4 = 12 bit?

I understand the difference between 8 bit and 16 bit in PS or After Effects - Precision.

And if adding just 1 bit increases color accuracy, How hard could it be to bump it up a bit or two? SD cards are cheap? So are Hard drives?

@disneytoy

4:2:0, 4:2:2, 4:4:4, are matrix to encode color in a frame.

exemple : "for 2 Green pixels (wich also, is luminance) we only keep 1 pixel of red and 1 pixel of blue. So, the color reproduction is subsampled.

8bit ; 10 bit ; 12 bit are the depth of gradation of the color ( in fact grey level for each (R,G,B,) pixel )

With 8 bit (R or G or B )pixels are coded on 256 level.

With 10bit = 1024 levels etc.

So, the 8bit common artifacts are banding ( on bright skys or when a lightsource is in the frame ) because 256 levels aren't enought to render the subtle gradients.

You can't add or substrate color matrix and pixel depht, that's absolutely not the way it works.

Adding 1 bit does not improve color accuracy : you can't invent a information that does not exist, ( ie an information that didn't pass the matrix ) but it improve color rendition ( you can switch between more levels of grey ).

woow i´m impressed..you guys should build a team an release "the camera" I realize now that I am just a camera owner...this is rocket sience

@DealjagdLtd About high ISO samples...

Vitaliy mentioned it above already but just to be clear: The photo, audio and other questions and answers are up.

Go here and then scroll down below the green questions only. Ther ae the 4 categories: video, photo, audio and others.

IMPORTANT: I could not ask all the questins below. I talked a lot before and after the interview, I tried out a lot. A lot of the answers come also from there. I answer all the questions to the best of my knowledge. I hope they are all correct, but I can not guarantee.

When there is “No information”, I either could not aske the question or find it out, or there was just no information available, also from the Panasonic people. They did not get all technical information from Japan, and they were not technicans but either PR people or from the markteting. I hope the information is useful for you. Please also have a look at the video interview, as soon as it is finished. There may be things I have missed here.

Also, I LIKED THE GH3. It had a good feel and I was very impressed witht he low light and sharpness in the videos. No matter if 4:2:0 or not. It will be a very good camera. Perhaps not all what we have expected or hoped for, but there may be alterations in the final firmeware, firmware updates and there is Vitaliy :)

@narechk

I concur that it is interesting read, and normally eoshd links are not permitted here, but we'll leave one for some time. So, Voldemort could move faster to light side of the force.

So...according to Mr Yoshi Inoue the GH3 HDMI output is 4:2:0. That's disappointing.

@towi Banding is inherent to every videocamera that use 8bit signal processing, but that's right, different type of compression (DV - AVC - JPEG, etc) may reveal more or less this artefacts.

@Vitaliy_Kiselev If all the active people of this forum put their strenght and ideas together, you guys could easily build a New Camera from scratch. With all those fancy features "we all want" and simply destroy the market out there! Setting a new starting point! So all the companies have to offer more and more, but hey less pricy! It has to be done from everybody for the masses , basically like this forum does in a awesome way! Like doing a kickstarter project but in this website! (not there obviously!)

ah i forgot but do u work for panny?lol

@Vitaliy_Kiselev

Maybe it's not the best moment/place...

Why you do not open a GH3 body donation campaign? Pre-orders are already opened. Is it too early?

'EOSHD: Is it a Panasonic sensor? So it is not a Sony sensor?

Inoue: Ah no comment!'
