So I wonder about using Resolve+BRAW to create an extended video b&w display lut that could be used as an aid for focusing; that also would make BRAW film mode recordings in full color; in other words usable for full color BRAW film mode recording by not baking the display lut into the recording itself.
1.) Light a 18% gray card and do a custom white balance with the P4K/P6K etc.
2.) Use the false color to expose it @ exactly 18% middle gray.
3.) Shoot a clip of this in BRAW, film mode.
4.) Bring this into Resolve. From the raw tab, desaturate the color and apply the Gen 5 extended video lut.
5.) Create 3D cube lut from the above.
With the viewing lut thusly created and uploaded into the camera, you should have a b&w extended video viewing lut that would make the LCD display black and white imagery with extended video contrast edges for the colored peaking to act upon.
Would this work?
For your info: here is a compilation of different setting to compare focus peaking. BW of either BRAW video or BRAW Ext. Video is significantly more helpful than colored ones.
I know the choice of color for the peaking matters, esp, in my testing. It is true either green or blue is better. However, with an overlay of B+W LUT, it does not matter what background you are shooting. All three colors will stand out more on B+W.
So, if BMD can add Video B+W or Ext. Video B+W LUT, it will be awsom!!
P4K BRAW Video, BRAW Ext. Video, and BRAW Film (Top, Middle and bottom)
Focus peaking level set at high
LUT, the same black and white LUT I used before
