It´s academic because ProRes is by design a visualy lossles codec, so from 422HQ to 444XQ you wont notice any perceptual loss on detail and color resolution.
444XQ has a lot of bandwith and will encode much more color information per pixel, thats great if you´re planning on upscaling a shot or you´re doing green/blue screen vfx shots.
Even for film productions and TV drama shows 422HQ is more than enough for capturing data. Of course RAW would be very nice, but 422HQ is a standard intermediate CODEC used by most networks for mastering.
I had agreed with everything you said and simply liked the comment and moved on.
Now I'm sitting here, months later, wondering if I should be taking the plunge to get the RAW license. In terms of color correction and really making my shots look beautiful in post, am I gonna REALLY see any difference between 4444 XQ and RAW? Besides half the file size?
My understanding is that ProRes RAW is compressed RAW (and we need to buy a license because RED owns a ridiculous patent on it). And that's why it's half the file size.
Or is it a situation where RAW is recording just the single set of 'raw' brightness data, and 4444 XQ is recording as three separate color values (Y Cb Cr)?
And where is there information about the bit depth of RAW vs 4444 XQ? |
