I have a 2010 mac pro 2.66 w 12 cores 36 megs ram running 10.8.4 - I have 5.5 and CC installed and the video card is a nvida 570
When I render a :10 comp the render time is :40 sec and is the same in both cc and cs 5.5. When I render a 4:00 comp the 5.5 takes 4:00 but the CC takes 17 mins . I am rendering pro res in both cases and the multi thread settings are the same in both . Both are turned on , So why is CC so much slower ?? The CC version is not 12.1 , it's 12.0
Know lots has been posted on this subject but not seeing an answer
Oh wow now that is a well prepared comparison.
Hopefully someone here can help, also struggling with this one.
So I did extensive testing of the project to try to trouble shoot and I found some very interesting results.
The original project was created in 5.0 and opened in 5.5 and rendered, it contained video footage and graphics. When it was render in 5.5 it rendered in 4:27 . When I opened it in 12.1 and rendered it was 18:00 . I then started turning off layers and my render times shot up . basically layer 12 had two animated masks on colored solid. With this off it took 8:30
I then imported the project into 12.1 and saved it , reopened it and with layer 12 off it took 5:11. So importing and saving the project made a difference. Now I recreated the layer 12 in 12.1 from scratch and turned it on an my rendered time was 6:50 .
So there is something going on with projects being converted from earlier versions - Now to really test this theory I would need to recreate the project from scratch and compare to the 5.5 times.
I also found that with 32 gigs of ram my magic number was 11 reserved for other apps ...
Hope someone can jump in and add some light to this
