Now, if an HD image could be recorded on camera using Redcolor 3 and RedlogFilm, well........
I am not looking for anyone here to "give me the answer I want". I am simply interested in provoking a good disscussion about things everyone seems to understand completely yet constantly offers up different definitions by way of zero explanation.
4:4:4 is a ratio and fundemantly refers to 1:1:1 or equal RGB sampling. And as you say the Epic nor its R3D file contains 4:4:4 color information at 4K. Unfortunately, the RGB image from the Epic is only decoded at its native resolution (4K). From there it can be resized to 2K/HD but it is not re-debayered for a proper HD 4:4:4 output by using adjacent RGBG pixels to calculate finer color rendition.
It would be great to have this option though...
"not re-debayered for a proper HD 4:4:4 output by using adjacent RGBG pixels to calculate finer color rendition" - I'm sorry, but with statements like that you really don't know what you're talking about.
Well, you've told us "but it is not", so to say such a thing you must know "what it is"? And what is "re-debayered "?
To answer your question, typically a full-demosaic is performed followed by a downsampling process. We provide for a number of selectable downsampling filters, all of which use adjacent pixels.
