Scarlet & Epic 5K resolution only 1667 pix?

[Ken Martini]

Difference between 1080 X 1920 3 chip camera and Epic 5K 1 chip:
Divide 5K by 3 and you get a 1667 pix Epic camera.
The 3 chip delivers 1920 pix, a higher resolution.

Is my math wrong, or did Red make up new ways of measuring pixel count?
The truth will set you free, I think

The main compelling reasons it seems to be in this camera system is the frame size, PL mount, and cost. You would get less artifacts from 3 chips verses 1 chip.

Your math is wrong.

Your math is wrong.

Damn wrong to be precise...

Very wrong, you are measuring apples and oranges.

RED is RAW.

Look up debayering and converting to RGB and you'll find your answer.

[Josh Negrin]

Where did you get those numbers? Also note, the RED is a single chip camera. The RED's sensor alone is far more advanced than most pro three chip cameras on the market and all the prosumer three chip cameras.

Also, there are many other factors to consider when purchasing a camera; the sensor is a big one, recording format (filetype, bitrate, etc.), and workflow, to name a few more.

You have much to learn, young grasshopper. But that's why we have this forum and we're here to help.

Wow, everything you said was skewed.

As was said, look up Bayer pattern CMOS sensors versus 3 chip CCD's

The 3 chip 1920 camera will deliver a 1920 horizontal image.

The 5k Epic will deliver a roughly 5000 horizontal image, (with the MTF of roughly 4k)

On a per photosite count 3 1920 x 1080 chips have 6,220,800 photo sites to deliver an image that has accurate color and sharpness with 2,073,600 pixels. Ergo 33% effective.

The 4k Red one, a 1 chip CMOS with active recording area of 4096 x 2304 has 9,437,184 photo sites. This delivers an image with 9,437,184 pixels. Now since it is a bayer pattern it's accuracy lands somewhere around a 3.2k image which would have somewhere around 7,361,003 pixels, or 78% effective.

To start....

Doesn't bayer pattern affect also vertical resolution? If bayer pattern reduces resolution by ratio of 3.2*1024 / 4096 = 0.8 then 'effective' resolution would be (3.2*1024) * (2304*0.8) = 6039798 pixels, or 64%. Or am I missing something here?

Or am I missing something here?

Yes, the fact that resolving power (i.e the system level resolution) is usually measured in one direction at a time, normally horizontally...

[Daniel Browning]

The 3 chip delivers 1920 pix, a higher resolution... less artifacts

Yes. Also, the earth is flat, snake oil cures all ailments, tinfoil hats stop aliens, and I have a bridge to sell you.
