Well that GTX should work even better than a quadro. make sure you have the latest
driver installed plus the latest CUDA. I’d try the quadro anyway, that should definitely work.
as for the codecs, here’s a paste from a previous post i made when I fixed the pro res offline issue
in CC 2014.1
“1 update to the latest apple codecs 1.02 (I found 1.05 and updated…no change)
2. delete the dvcprohdoutput.component from the quicktime library.”
my particular issue was the dtshd-ma decoder so I just deleted it as it won’t work
anyway in mountain lion. look for other plugins that seem out of the ordinary.
/mac hard drive/library/application support/quicktime/plugins — i think, maybe google it.
also try clearing preferences, caches and possibly install latest Avid Codecs as I
think you were using the non-adobe avid codec files.
