That's fairly much what I was thinking. My only reservation is I understand that with the S series cameras the camera and the VA share some of the processing in the creation of the raw file. I wonder if part of that processing includes the lens profile corrections.
As far as I know there’s no way to accomodate a lens profile in BRAW.
Just like in every other raw cinema format. They don’t support lens profiles because the problem is that some of these things are dynamic.
Think about CA for example. It’s on contrast right? What happens in a shot if the shot starts with no CA, pans into a scene that has high contrast and produces CA and then pans off again?
It’s very very difficult to dynamically do CA correction as anyone who has tried doing it in the cDNG days will tell you.
Other lens geometry corrections can mayyyybe can be applied but again, you’re going to likely see weird things happening on vertical lines as you pan through something because the correction CHANGES based on what’s in the shot AND which part of the lens is being corrected.
There’s also no real mechanism for intra frame metadata. For example, tracking focus distance accurately OVER TIME within a clip. There are only external animation techniques that are guaranteed to work.
These kinds of areas are what we hope the BRAW developers are working on because it’s only one you track all this info action by frame rather than clip that you can maybe start to do these other processing techniques.
