Gh4 4k downscaled recording to Atomos Ninja Star?

The Blackmagic cameras are good mainly due to lack of compression. 10bit has very little to do with it. I think 10bit could be the most overrated attribute of video acquisition ever. I literally can grade 10bit GH4 4K and 8bit together on the same timeline the same way and pixel for pixel they're identical! And it doesn't sort out banding either. We are shooting with two gh4s.. one is a A cam that has a 4k recorder and the other is internal. The color is better and the footage looks better on the recorder but I never thought weather or not that has to do with 10 bit vs internal compression. I am thinking of getting a ninja star and running 1080p to it with downscaled 4k footage as the b cam. We only use pro res LT tho because of the file sizes get crazy with two cameras.
