Solo Filmmaker - Is ProRes RAW a Good Safety Valve?

I am often a crew of one. Every once in a while I get back to the office and find that the white balance was off or something is blown out (I live in Florida and there are times where it is difficult to see the screen). Would it be worth the extra work to shoot ProRes RAW and be able to fix WB and ISO in post? I shoot with a Sony FX3 and I am thinking about getting a Ninja V.

I've shot and edited lots of ProRes RAW on the FX6 and A7SIII (similar to FX3). IMO it's not generally worth it. It does not help dynamic range, as that is determined mostly by the sensor. It can help adjusting WB in post, but we got by without that for decades. Using a good codec such as Sony's 10-bit 4:2:2 XAVC-I or externally recording ProRes 422 will allow significant WB adjustment in post, provided the WB as shot was vaguely in the ballpark.

Even with ProRes RAW you still have to adjust WB in post, it just makes it easier. But even then there can be issues, such as mixed lighting. E.g, you shoot an interior scene with ProRes RAW but the venue has fluorescent ceiling lights which vary from 3500K to 5600K. ProRes RAW lets you perfectly dial in any *single* WB color temp,  but with mixed lighting some will require secondary correction.

Another example is if the lighting is uniform but you don't have a measured WB reading, nor any neutral white or grey object in the scene. Using ProRes RAW you can adjust WB in post, but to what value? You could do it "by eye" or crop down to a patch of skin and use the vector scope, but that's no different than using non-RAW video. 

Some other downsides to ProRes RAW (on Sony): you lose in-camera noise reduction so the resultant material is typically noisier. It responds well to Neat Video but that's an additional step in post. You lose lens profile corrections, focus breathing compensation, and Active Steadishot stabilization. You also lose Sony's gyro data for stabilization in post. 

You could nonetheless get a Ninja V which would (1) Give you a larger, brighter monitor, (2) Provide additional shooting aids such as waveform to get the exposure right (3) Let you record in ProRes 422 which is easier to use, and (4) Still have the option of shooting ProRes RAW.

Very helpful. Thank you.
