Colin Brougham Oct 13, 2010 2:13 PM (in response to SteveHoeg)Timelines rendered through AME are CUDA accelerated.
Usually they are, with occasionally rather ugly results (Battling Hardware MPE, Episode 2: Chunky Blurs), but sometimes, mysteriously, they appear not to be (Battling Hardware MPE, Episode 1: Cropping on Export). Working on a third episode of the MPE inconsistencies right now...
Ultimately, at this stage of the game, my feeling is it's better to avoid exports using hardware acceleration if you hope for any degree of quality and consistency in your exports.

rudo_fr Oct 14, 2010 2:25 AM (in response to rudo_fr)Ok thanks Jim, Steve and colin for your answers.
I have now better view of hardware GPU acceleration after your researchs.
Much of the time (differents video format) i noticed GPU are more used when you export directly from premiere and sometime hardware doesn't help rendering when it is used in render queue.
For the moment i have a hack GTX280 on workstation, but i would test gpu acceleration on GTX480M (clevo x7200) to see if it's better to work with nvidia hardware than matrox MXO2 for exemple.
Do you know if nvidia SLI work with cuda acceleration and premiere ?
Thanks again.
Rud.

jabloomf1230 Oct 14, 2010 11:33 AM (in response to rudo_fr)CUDA supports multiple nVidia cards and there is an option in the control panel for the driver to enable multiple cards (and even specify which cards to use for CUDA). SLI is not needed to do so. Unfortunately, the software has to be written to take advantage of this feature. Maybe Adobe will add this to a future update to the MPE.

rudo_fr Oct 15, 2010 3:48 AM (in response to rudo_fr)ok thanks,
we will see adobe and nvidia developement of this hardware acceleration in futur cs version.

8. Re: AME & CUDA ACCELERATION
David Zeno Oct 15, 2010 9:10 AM (in response to rudo_fr)I just did a test,
I have the GTX-470 video card.
I rendered 31 seconds of a video using the "export to media" function, and it took 44 seconds to render it.
I then rendered the same video using the "Queue" function, and that same footage took 1 minute 1 second to render.
Seems that using the "Export" feature renders faster than Adobe Media Encoder ( AME) does.
Not sure if this is true with all systems, but with my test, that was the result.
Dave.

Harm Millaard Oct 15, 2010 10:05 AM (in response to David Zeno)David,
The inconsistencies in the time it takes with Direct Export versus the AME Queue have been reported and are being investigated. These strange results only apply to AVI and MPEG2, not to H.264 encodes. In some cases it can take more than twice as long, in other cases only 25% of the time of direct export versus AME queue. Apart from some threading issues with the exporter modules that are also being investigated, I'm not aware of a solution yet.

10. Re: AME & CUDA ACCELERATION
Marcus Koch Jun 13, 2011 12:57 PM (in response to Harm Millaard)I just reported my case in the Encore forum. I'm eporting HD1080i50 material to MPEG-2 DVD. Direct export is 9(!) times faster than in queue. I only have a single layer of video with titles and short animated banner sequences that are on a second video layer. 95% is just plain one layer video.
