ARRIRAW Debayer settings

[R.S. William]

Hi Everyone,

I am working in a VFX/CG heavy project and all the live action VFX pulls are from ARRIRAW files.

A colorist informed me that if After Effects debayer might be a problem. That is to say, if:

1) All the VFX pulls are debayered by after effects

2) all the standard (non VFX) shots are debayered by the colorist in Resolve

Therefore, possibly:

3) All the VFX shots will fundementally not match with the non-VFX shots due to the debayer difference.

Is the above scenario a reality?

After effects debayer settings (via interpret footage menu) is somewhat basic compared to that of other color applications, and I haven't found much information on this on the web, so I wanted to check here.

It's my intuition that Adobe's deployment on arriraw technology is done using tech provided by Arri, so the baseline result shouldn't vary much across platforms.

Any help would be greatly appreciated.

Respect,

Rem

I can't offer an authorative answer on that since I rarely ever have worked with any Raw formats, but my thinking is that the actual debayering would not produce different results with identical settings. After all, it's just instructions on the physical sampling pattern and color clipping vs. the reconstructed pixels. If there are any differences it's more likely the secondary interpolation/ antialiasing algorithms and color management and those could in theory be matched. It's not the preferred in Resolve, but it does have a bicubic filter. Anyway, I guess it's a case of setting aside an hour of your time and figuring things out.

Thanks for your thoughtful response. @Mylenium  I pretty much agree with you. Tho some of the colorist folks I spoke with had me spooked about this issue. 

Indeed, I'm doing tests now and so far they appear identical in detail and color. Color management using ACES via opencolorIO plugin.
