Raw or baked in, I guess it depends on the project.
Me . . . I want our dailies to have the closest look possible to finish and I love it when we have to produce dailies and proxy's from the RED vs. any baked in look.
The RED's with the Red Rocket and the newest cinex make a great workflow for us, using Cinex or Resolve to set a file, copy the look, paste it onto a bunch of files and let it rip.
But I love Resolve, especially with the Rocket card because it runs real time or faster.
I did this in Resolve, from dailies to proxy's to finish (minus the flash which was in the NLE) and the client didn't have to make a leap and ask what is it going to look like.
For file size, well, all files today are big, though nothing is larger than 442 pro ress as in 2k it's almost as big (may be larger) than a RED 4k raw file.
I think a lot of people fail to recognize that everyone works differently, everyone rolls their own in workflow and style.
Red catches a lot of heat . . . some they deserve, most the don't, but their business model allowed me to buy three real cinema cameras for less price than one Arri and btw I think Arri makes a very nice camera.
PS. Speaking of large file sizes I had a European ad agency request a long clip in uncompressed proress, the file was huge even in 2k, and we have fast load times in our London space and it still took 12 hours for it to go up probably about 4 to 5 hours to download, which was funny because the final video they edited was for mobile only.
