Good to know. I will be in contact with the IMF facility later today. They have told me they could take a ProRes file for IMF creation. What you are saying seems to make sense given what I'm hearing. I really appreciate that insight.

I could be wrong, but if I'm not mistaken Clipster is a Red Hat Linux Platform and AFAIK there is no DNxHR codec for linux yet, not even Avid Media Central (that also runs on RHEL) supports DNxHR.
There is no QT LE package for Linux and that's why they might be regecting you the DNxHR. Clipster hane decode and encode ProRes and DNxHD natively, but I doubt it could do DNxHR.
My two cents.

Just wait till I have to use QT Change to save the day on the final delivery file. Perhaps that will excite you as much as the potential of saving 4.5TB of wasted storage and a 45 hour unnecessary render does me.
Yawn

I have yet to contact them directly so I'm holding off judgement on this.
But seriously a 5 TB file that takes days to generate over a .mov with the same quality in the final product that is 600GB and exports in half realtime once I've rendered the sequence is unacceptable? On sheer data size alone that would be beneficial to the IMF facility as well. Perhaps I am being misinformed as to their requirements but to me it's a no brainer that it would be better for all parties involved to use a QT to make the IMF on this project.

It probably doesn't occur to them that you think their requirement of delivering DPX is onerous. It's their everyday experience and has been for years.

But it's me the middle guy that is having to jump through hoops for differing assets between QC and IMF creation. I'm not saying that's wrong but it is really inefficient and seems a waste of bandwidth.
Here in a nutshell is what doesn't make sense to me. I'm told that Clipster can in fact make an IMF from a QT file. I have a sequence that is DNxHRHQX video essence. I'm told that more than likely if the Clipster system has the Avid LE codecs installed it will be able to make an IMF from a QT DNxHRHQX. Now it that's not the case then certainly the ProResHQ version I have made should work. This is all contingent on the fact that I'm told that Clipster can in fact make an IMF from a QT .mov. If this is wrong someone please correct me.
Given the above I see no reason why I should be required to deliver a .dpx asset to be used for the creation of the final IMF. Given my footage was Panny AVC Intra 422 10 bit transcoding it to Avid DNxHRHQX shouldn't effect the image quality in any meaningful way right?
So if I have basically camera raw quality material in the Avid DNxHRHQX video essence exporting that to .dpx isn't going to add any quality. To me that means if Clipster can in fact make an IMF from a QT, be it ProRes or Avid DNxHR, then where is there a benefit to delivering as .dpx?
I'm not trying to be right here I'm trying to understand what logic there is in creating a lengthy export process to an unwieldy 5TB dpx file for what seems to be no gain in image quality. There in lies the rub I'm trying to figure out.

We are using a preferred vendor for QC and another preferred vendor for the IMF creation.

If John chose one of these facilities, it is their responsibility to ensure the IMF file they create passes NFLX final QC.
In order to achieve this, they need a pre-conversion QC to make sure all assets are in check and the programme is valid, both technically and subjectively.

This is exactly what I was thinking. What's the point of QC if it's done with a file that isn't the one delivered for air?

The QC should be on the delivery file.
At worst you'd QC an intermediate file but then you still have to QC the final file.
If the facility doesn't understand that then I'd find one that does.
