I'm running Premiere CS6 on a 2009 2x2.26 GHz Quad Core Mac with 16GB RAM (ATI Radeon HD 4870).
Adding a single simple effect makes real time playback impossible (choppy, freezing), and makes endless rendering necessary. Can that be? Tech support says the moment I add an effect (in my case Fast Color Corrector on a 1080p MTS/AVCH or ProRes file) I need to render.
This is not the "real time work flow" Adobe is advertising? Am I missing something? I can't keep rendering every clip just after applying a simple color correction (even ancient FCP7 could handle some color correction real time)...
I am aware I'm not running on a CUDA card. BUT is my Mac, out of the box, really incapable of playing back single files with one simple effect? How much improvement would an Nvidia Quadro 4000 give?
I'm just switching from FCP. Or at least I'm thinking about it...
Thanks so much for your help.
Real time playback of clips depends on your hard drive and CPU. Only effects and such are handled by the graphics card.
So...if you have clips without effects that don't play real time now, then the graphics card won't help. If they play fine on their own and only stumble with effects, that is where the GPU can help (depending on the effects, not all are accelerated).
Thank you! Will it accelerate effects on any kind of format of clips? Someone told me that acceleration does not work with ProRes or other QT wrappers, as they "default back to the QT rendering", whatever that may mean? Any truth to that?
