Right, so that why I have my doubts about using ProRes technology, which uses Y'CrCb internally, applied to raw data.
From Apple's whitepaper:
"Apple ProRes RAW is based on the same principles and underlying technology
as existing ProRes codecs, but is applied to a camera sensor’s pristine raw
image data rather than conventional image pixels. "
It seems they simply mangled raw data into Y'CbCr, use ProRes compression and unmangle it back to raw.
I see many potential issues with that.
Not all flavors of ProRes are YCrCb. The 4444 formats can use RGB. That quote mentioned nothing about YCbCr. Besides I'm talking about going from YCbCr to raw being impossible. If Apple is recording the raw values which they have to be doing but converting to RGB or YCbCr on the fly that is totally possible and exactly what every other raw format does. Apple just optimized it to do it faster.
