Not that i checked

Not that i checked

The 5d doesn't resize the image from 22 mp to 1920*1080....It simply skips some pixels.

I havn't checked this but more or less all video cameras use the full sensor and then scales down the image. I'd be surprised if the same wasn't the case for 5D II.

It does skip some pixels to change to widescreen.

"lyrd" I don't think this is correct. In fact, I think a lot of video cameras work quite the opposite; that is, they upscale an put pixel count in where the imager is quite smaller (like half the pixel count) and then run this algorithm to make the image a 1920x1080. That is, in the case of the HVX200/A the imager is something in the 940/960x560/540 class and then uses algorithm to get to the final destination of 1920x1080 and if you do the math that is something like twice the horizontal and twice the vertical which is something like ~4x conversion. And most of them do this same mathematical magic.

There are a few (from my research maybe one or two) that do little magic; that is, they have a much larger imager like in the 1440/1280x1080/960 class (much larger than the former) and do either little math or no math to get to destination.

Someone correct me if I'm way off base here but when I spoke to Panasonic, Sony, and Canon, on the subject that is the conclusion they gave me from their tech departments . . AND . . none of that means anything positive if there isn't some kind of really HOT pre-noise filtering system to avoid "multiplying" the analog noise conversions which then get calc'd and (do the math) multiplied.

Follow?

The 5DII does not downscale the full sensor image, it simply skips pixels to get it's 1920x1080 image.

any idea how many pixels the camera skips?.. how many of them remain?

 

[Lee Wilson]

any idea how many pixels the camera skips?..

I have heard people say that it only records every third pixel, I am too lazy to do the maths myself - full sensor resolution divided by 1080p minus the 16:9 crop (or something like that).

how many of them remain?

On the sensor ? All the pixels remain !

In the final 1080p image ? 1920 x 1080 !

I just wanted to chime in and say that counting both pledges (where I have registered email addresses) and donations. We are now close to 2000USD which is a very impressive sum!

USD $4,000.00 now.

I have a suggestion: why not to enter in touch with skilled people in order to notice them about the offer? Eventually, let the hacker make the price as goal amount?

Both pledges now equal = $4427 !

Can the fellows who do the hacks on the canon powershots maybe help?

I have posted in their forums as well. They are most certainly welcome to help out or fix it completely

I like that Idea!
I'm about to update the original post. I will ask theme there to post it in the comments!

The images from this thing are amazing. This should really push some competition with the other guys.

 

[jamesmallonuk]

I hope the hacks get going as I am holding back until I have a camera that does manual audio. which makes me wonder why manual audio isn't the priority rather than aperature etc.

Isn't there a display mode on the camera that allows you to see the exposure as it is set for the picture you are about to take but you can't lock it for movie mode?

Wouldn't it just be easiest for some nice hacker to include a lock function on that camera in that mode? That doesn't seem like it would be that hard.

Just a thought.

Uhhh.. yeah I'm sure they are aware of that.. and as to difficulty. I'm sure it's hard.
