Mac's don't do 10bit processing/problems with FS700 12bit Raw & Resolve...

The director of a music video I have been shooting (who is handling all the horrendous AE work it needs) has had to completely re-encode (on his PC) all the 2K Raw footage I shot for it with my FS7OQ because Resolve (on my Mac) seems to have converted it to 8bit DPX files (despite me setting it for RGB 10 bit).

At least that's what he thinks explains why the DPXs I created look so terrible compared to the ones he created using AE. Does anyone else have any thoughts on this? I know that Macs don't seem to support anything other than 8bit displays but I had assumed they'd be able to handle 10, 12 & 16bit processing for still and video.

It would explain why I see more banding than I would expect from 12bit footage...
 
I would assume that this was actually the case (although I haven't used raw footage in Resolve, I have successfully worked with plenty of other 10bit footage in FCPX and AE on the Mac) this wouldn't be the first we had heard about it.

Which Mac / graphics card and version of Resolve are you using?
 
I use Mac After Effects all the time and AE works in 8, 16 or 32 bit color depth. When you export, it defaults to 8 bit unless you specify 16 (which you can make a preset for).

Pro Res 422 is 10bit and 4444 is 12bit, so you have to have it set to 16 bit (not the default 8 bit) color depth space which it then knocks down to 10bit or 12bit for final export. If he left it at 8 bit, AE does not automatically up-res it if it's set to Pro-Res.

AE is super slow for transcoding. He should use Resolve. However, I do all my final color correcting in After Effects and have never had a problem. There's a huge and very noticeable difference in banding when AE is set to 8 vs 16 bit.
 
After reading your post, I ran a test clip thru Resolve(my normal workflow). Never having delivered .dpx, I was curious as to your observation. After rendering out on both a PC and a Macbook Pro(nVidia video card), both dpx files report as 10-bit with MediaInfo. Don't think it makes a difference, but, in the Deliver tab, I unticked "Keep source resolution" and selected "Force debayer to highest resolution"
