Huh? Uncompressed RAW gives you more, not less, control and image quality during post workflow.




Yes, but you are misunderstanding what I mean by “workflow.” Clients don’t want uncompressed RAW. They don’t want to deal with it. It is something different and requires different workflow. When the day’s shooting is done they need three (often more) copies of the footage, including one that they can view on their laptop or is quickly uploaded to a cloud service. They also need a copy of the footage available in a video format with a standard LUT applied for viewing in a Rec709 environment. The files need to load into an Avid, or Premiere, or whatever. And they do not want to wait a day or even a few hours to get the footage like this — they want it when they leave set. Frankly it better be uploading during the course of the day. 

I know that uncompressed RAW is technically the best, purest form to get the signal from the camera to post. I’m the guy who helped introduce the production world to the Phantom cameras, which were the first uncompressed RAW systems generally available to most people (not a lot of Dalsa shooters out there). Uncompressed RAW is the best quality — so what? It is a more burdensome workflow because it does not deliver an immediate result in the form most clients want and it requires more memory which means more time in transfers. I will again state that a good codec such as ProRes with a standardized Log curve applied (C-Log/Log-C/V-Log/etc. - choose your camera’s flavor) is more than enough for 99% of professional production needs and it is easier for clients to use because it is what they expect. Is it technically as good? No. Does that matter? No.
