DPX vs ProRes444 for Log C Arri Alexa Mini LF Footage
on Jun 16, 2020 at 12:41:35 pm

Hello,

I'm in the process of color grading and doing VFX on a short film shot on the Alexa Mini LF.

My colorist told me to shoot Prores4444 saying that raw would be overkill so we followed his guideline and ended up with MXF files.

Two questions:

Is there a need to send dpx files to the VFX artist if the original shooting codec was ProRes4444? I normally use DPX but the colorist is telling me that it's an unnecessary upgrade.

Secondly, if I export the files in Adobe Premiere as ProRes4444 after receiving the color corrected footage, would it degrade in quality at all? (A friend told me to support the color quality, I should use after effects and export with 32bpc.) To be honest I have no idea what he means since I'm not doing any compositing work.

Thanks!
