Re: [Avid-L2] Re: Using Resolve to add Lut to Camera Log C Render time of Red Rocket vs GTX-680?

 

I heard back from the DIT and he confirmed the Amira does not shoot to Arri Raw.  The best it does is ProRes 4444.  I was told that there was a license fee to record to dnx, something like $5,500.00, so most rental houses don't do that.  I was also told that this DIT felt that DNX isn't as robust as ProRes.  Now I don't think I agree with that statement, that sounds like a lot of rental house justification for not purchasing the dnx option. 

I also learned that the DIT is doing the same process as I am using Resolve to create DNX media as that is what the Post Supervisor requested be delivered.  So whatever quality hit is involved in going from ProResHQ 422 to DNX through Resolve has already been baked into the previous shows we've done without us knowing it.  I would be interested to know more about the theoretical issues here and how that is weighed against the practical of will I ever notice a difference.  I have always felt that all the years of editing 3/4 to one inch video has permanently created a drop out compensator in my brain so I don't always notice small issues that those QC folks might see.  Without my frontal lobe drop out compensator I would have gone even more crazy over the years.

I could if they had Ver. 7 Avid.  I realize I could do it in color correction but the LUT gets me closer to correct to start with.  Whatever quality hit it takes is completely undetectable in the end.  I'm talking HDCam to cable network.  Not 4K UltraHD ;-)  I'm cranking through and it may seem like a small thing but stretching things out from LogC takes more time that I don't have, but I do have a Resolve system cranking away in the machine room.  I'm not saying this is the cleanest way but it's nothing anyone will see at home.  I realize there are differing views on this. I am curious why the Camera Negative as they label it from the Arri Amira is ProResHQ 422 and not the typical Cam Raw I get from Alexa shoots.  Perhaps it was a production choice to save disk space etc...  In the past they have been shooting 4 and 5K which is overkill and rather taxing when it comes to hour long plus clips.  I'm waiting to hear back from the DIT as to what was the reason behind this.
