Care to share the name of the engineers you spoke to? IhHave a couple of questions for them...
Also, you clearly stated to them that you are on a Mac with no expansion chassis - right?
thx,

Subject: [Avid-L2] Some information from the Blackmagic Event in Burbank
I made it to the Blackmagic event in Burbank and got to speak with the
two local Davinci techs from Blackmagic. There seems to have been some
misinformation from our Resolve consultant regarding the proper video
card to use. According to Blackmagic we should have installed the
GTX-680 that was suggested to me by many others. The Blackmagic
engineer told me that is their preferred card of choice today. They
also told me that when we tested the two Quadro 4000 cards we were
either running outdated software or the system was mis-configured not to utilize both cards. The last two software builds allow two graphics
cards to work with Resolve without one being solely dedicated to the QUI interface. When they added the second card either they forgot to update
the software or they were unaware of the new capabilities. Also it was a surprise to me that regardless of what we've been told Resolve actually runs better using the Red R3D raw files than with Avid DNX 220 media. Apparently the Avid media is more
cpu intensive on Resolve, in a symphony the Nitris DX handles the DNX
decoding so it plays well but in Resolve it is very taxing on the CPU.
It would definitely be worth looking into swapping our Quadro 4000
card for a GTX-680, a quick google search shows that the 4000 card is
two to three times more expensive than the GTX-680 and I don't
understand why we were told that was not the right card for Resolve.
As far as our workflow issues with round tripping the Davinci techs want
to take a look at our aaf and see what they can find out. I believe I
got to the bottom of many of the issues but the skipping frames seems to be something that will require more research on Blackmagic's end. As far as I can tell there is still an issue with mixed drop and non drop source time code. The Blackmagic engineers said that 9.1.15 the latest build had some improvements there but as I was testing with 9.1.15 it seems there are still issues. Not being able to have mixed source codes really makes round tripping not very viable for most of my shows.
I was glad to get to talk with the engineers and they seem willing to pass on the questions to the design folks so hopefully more will be revealed.
