Upres Arri UHD Prores to Cine 4K for DCP? (2 replies and 3 comments)

Hi all, I recently shot a short film on an Alexa Mini w/ Zeiss Superspeeds, using the UHD ProRes 4444 XQ in lieu of ARRIRAW, since our camera rental didn't have it. 

We framed for 1.85:1, and have a 16:9 'negative'. 

I would like to uprez it to cine 4K so I could create a 4K dcp, but have no idea how to do a marginal uprez, most youtube videos address HD or 2K to UHD. 

How can I get this to the 4096, so then I can crop to 3996x2160? 

Or would it be easier just to do the DI at 2K, as it would be easy to render the colored files at 1998x1080?

Thank you for your help.

What program are you finishing in?  It should be easy enough, just make sure the settings are such that the whole frame is scaled and resized to 4K instead of cropped.

Not sure, it's being edited in Premiere Pro, I'm not sure if our current editor is going to do the online editing or not. Possible transfer to Avid for that. I assume the color will be in Resolve, but I'm not 100% sure.

How do you scale the whole frame? Also what resolution should we up it to from 3840x2160 to have enough resolution for a 1.85:1 crop?

...The quality of an upscale strongly depends on the software you are using. Keep in mind, that with every upscale (even a small one) image detail will be lost. I would definitely go for the 2K downscale, because it will increase the image quality, and the dcp will look nicer.

To get to 2K, we should just render it out at 1998x1080 then? Or is there more to the downscale?

Edit in a software that you prefer, but send original shooting to Resolve and do color and upres in Resolve, it had better tools and more quality than premiere and Avid.
Resolve had many tools to upres, manage all pixels to upres without add oversharpening or other bad post work like editing software.
Both Premiere and Avid could send a edit decision list to resolve, an XML from premiere or a file from Avid to load in Resolve the original file, and manage the finishing with them.
