C200: Is Cinema RAW Light Going To Be an Orphan Format?

[puredrifting]

I know, funny how the landscape is constantly shifting underneath our feet as we write posts, they are almost outdated right after we post them. Hard to keep up there are so many changes and announcements.

And now we know why: Black Magic launched their own RAW codec.
Interesting analysis over on CML: BM RAW codec is similar to ProRes RAW, both are DCT based, etc, etc, etc
Not sure I am allowed to link to it here.

In the theme of this thread: With more fragmentation in the RAW codec market and feet dragging support of ProRes RAW from Black Magic, I think Canon RAW Light will do just fine!

If so I didn’t find confirmation of DCT vs wavelet. There was speculation that it’s deBayered to RGB but without any color transforms. If that’s true it’s not raw, it’s semi-cooked or half-baked (software terms). To be fair, it’s more like medium well done since deBayering is massively more complex and expensive vs trivial color transforms (especially when they are linear). If it is cooked RGB and not raw, DCT makes sense (very similar to ProRes).

No, that is not the link. Look for 'BRAW codec - Analysis', by Daniel Rozsnyó

A slight tangent, but is anybody familiar with whether BRaw and CRaw are encoded with linear or logarithmic encoding?

Certainly far from an area of expertise for me, but my understanding is that the Arri pipeline goes as follows: 2x 14-bit A/D converters -> 16-bit linear processing -> 12-bit log encoding. The 12-bit log encoding is equivalent to 16-bit linear – so, for example, the Arri 12-bit files are equivalent to Sony 16-bit linear raw files.
