RedRocket scaling workflow
I’m dong a job shot on epic @ 5K and it seems to me that the grades are being applied upstream of the scaling. In other words, even though my timeline is 1080p, and I should be scaling down to 1080p via the RedRocket card, it seems that the grades are being applied to the 5K shots in other words the GPU must do the image processing at 5K which slows the system to a crawl.
Is that how resolve always handles R3D? Is there anyway to scale down to 1080p on input via the rocket hardware like you can in scratch?

I can get 9 nodes of blur in 1920×1080 timeline at 25fps on 5k epic using quarter debayer without a rocket. (4.5fps with 5k timeline)
Surely the rocket will work the same way or better?DaVinci Resolve 10.0.0, FCS3, FCPX

Rocket doesn’t do 5K in RT. You get about 18fps. The debayer quality determines the res. full res debayer will spit out a full res image then resolve scales down on input. Set it to half res premium debayer and you’ll be dealing with much more manageable 2.5K frames.

It seems that different software platforms access the rocket hardware differently. The rocket card has the ability to do a high quality hardware based downscale to lower resolution so that you can debayer at full/full and scale down via hardware to a resolution of your choice. This is different than doing a half res debayer. At least that’s how it works in scratch. It seems that resolve doesn’t have the capability to use the hardware scaling on the rocket is that correct? Also I interested that resolve allows you to decode at less than full / full debayer quality settings which I have not seen on other platforms… I was under the impression that output of the rocket was always full quality debayer… Mysterious.
