Adobe Premiere Pro CS5.5 CUDA encoding slow??

[Brainiac]

Hi all

I just acquired a Quadro 2000D video card to run PP CS5.5 with. According to videos on YouTube, posted by end users and some by Adobe, video encoding(?) should be faster with the MPE GPU acceleration enabled, as opposed to software mode. I, however, am NOT seeing any difference in encoding times. For example, if I drop 2 AVCHD clips on the timeline and run AME with MPE GPU acceleration and software only, the encode times are the same. My card is on the approved list, BTW.

Am I expecting too much??

Running I7-860 2.8 GHz, 8 Gigs ram.

Encoding isn't affected directly by CUDA. MPE uses software enhancements and CUDA to accelerate rendering of some transitions and effects, so in effect it reduces the bottleneck, and more CPU resources can be allocated to encoding. So if you have an FX heavy project with multiple layers, effects, transitions, you will see a bigger difference , sometimes 5-10x faster, or even more

So for a no edit/effects project, expect similar export/encoding speed, because nothing is accelerated

Note this is different than the 3rd party Elemental accelerator, which does use CUDA + quadro to encode for CS4, I think support has not been added for CS5

Thanks for the reply. It cleared things up for me quite a bit.

Is there a way to increase render threads in Premiere? And turn down Preview RAM?

In the Effects tab there are three buttons. The first one will expand and show only the Accelerated Effects. The second button displays 32-bit color effects and the last one displays YUV effects. If you put a project together with just the Accelerated effects you should see better render times using the GPU.

Here's some more information about what is accelerated by CUDA:
