1. Re: System Becomes Unusable During Premiere Pro CC or AMECC export
cpachris_1969 Feb 8, 2014 2:19 PM (in response to cpachris_1969)I meant to add too that task manager (in the brief seconds that it will update) indicates that the CPU is not even taxed at 100%. It kind of has spikes and periods of inactivity during the exports. GPU load doesn't get above 30%, and yes...hardware acceleration is on.

JSS1138 Feb 8, 2014 2:54 PM (in response to cpachris_1969)Is it only that sequence that is giving you trouble, or all of them?

cpachris_1969 Feb 8, 2014 3:54 PM (in response to JSS1138)It was my first CC project. So I don't know for sure. I'll start another project and eliminate some of the complexity. See if that improves things.

4. Re: System Becomes Unusable During Premiere Pro CC or AMECC export
cpachris_1969 Feb 8, 2014 5:34 PM (in response to JSS1138)Ok. Backed and armed with more information. I created a new project, and added a little 10 second video clip that came from my DSLR. Similar to the video I was using in the previously mentioned project. I added it to a sequence, and started an export with nothing else. It only took about 25 seconds to complete. So then, I started adding different effects and other assets to the clip to build up its complexity to something like the one I was originally using. I exported the sequence after each change, using AME. I did test using Premiere directly for the export a couple of times...and the export times were always similar to AME.
1) Added a second video clip, and used crop effect to make it appear like split screen. Still took only 30 seconds, and had no freeze ups.
2) Replaced one of the video clips with a linked AE composition. Still took only 33 seconds, and had no freeze ups.
3) Added a color balance effect to the AE comp. Still took only 33 seconds, and had no freeze ups.
4) Added a title. Still took only 33 seconds, and had no freeze ups.
5) Added 4 high res jpeg stills to the sequence, extending the time by about 8 seconds. I now started to experience the hangups while the export was running, and the export took 1 minute 30 seconds this time.
6) Added cross disolve transition between each of the stills. Now the export took more than 7 minutes.
7) I then deleted the cross dissolve transitions I had added in the last step...and the export took more than 10 minutes. Huh? Took longer by removing the transitions.
8) I removed the jpeg stills altogether from the sequence. Export still took 10 minutes.
9) I removed the jpeg stills from the project. Export still took 10 minutes.
From the moment I added the high resolution stills to the project, the export times became unreasonable, and I also lose control of the screen/mouse updating while the export was running. But what doesn't make sense is that it didn't improve even after I had removed the jpeg's from the sequence and even the project. Does this make sense to anyone? I think the initial fast exports prove I don't have anything really wrong with my setup. But I can't explain the extreme slow down and loss of updating screen/mouse. Does this trigger any ideas from anyone?

5. Re: System Becomes Unusable During Premiere Pro CC or AMECC export
cpachris_1969 Feb 8, 2014 7:45 PM (in response to JSS1138)More testing....I think it might have something to do with graphic card acceleration and VRAM. If I flip the switch on my original project so that it is software only instead of gpu accelerated, it finishes the project in about 2 minutes. Instead of the 2+ hours it took with gpu acceleration on. I ran a monitoring log on my GPU usage during one of the gpu accerlerated runs, and it's using up every bit of my 2GB of VRAM. I'm wondering if AME CC is not handling the situation well when the VRAM is fully used up.
And I'm also not sure what actually counts against the limit. Some of the jpeg stills I was using were 5,184 X 3,456. So they would take a full 1 GB to display. But since I was using cross dissolve transitions between the jpegs, does AME have to load up both of the jpegs at the same time to create the cross dissolve? And if so...it would surely be using up all of the 2GB of VRAM. Does this sound right?
I want to solve what is going on here...even though the software only export times are excellent.

Mark Mapes Feb 8, 2014 9:15 PM (in response to cpachris_1969)Are your GTX690 cards OpenCL or CUDA? If they're OpenCL, then you could be hitting the issues discussed in this thread: http://forums.adobe.com/message/5985267#5985267. (I would have pointed you that way earlier, but a little research led me to think that they're CUDA cards.)

cpachris_1969 Feb 8, 2014 10:21 PM (in response to Mark Mapes)The card supports both OpenCL and OpenGL with it's drivers, but are definitely CUDA cards.

JSS1138 Feb 9, 2014 2:50 PM (in response to cpachris_1969)In that case, OpenCL is not available, so I'm not sure if Mark's link applies here.
I'd say you're looking at a normal slowdown, having a more complex sequence, but the speedup when turning off GPU acceleration kind of throws that idea out the window.
Unfortunately, I don't have any others to replace it with, other than leaving GPU acceleration turned off.

11. Re: System Becomes Unusable During Premiere Pro CC or AMECC export
cpachris_1969 Feb 9, 2014 5:43 PM (in response to JSS1138)It's definitely not a normal slowdown. Not even really a slowdown....more like it simply stops updating the screen except every 10-30 seconds. And with the additional testing I've done, it doesn't even have to be something complex to trigger it...because I can make it do with ONLY the high resolution jpegs if I add them by themselves to a sequence. So I think it defniitely has to do with the video cards and their memory. I don't think there is a problem at all with normal operation of the GL accelerated exports, because as long as I don't have an asset that has taken up all the VRAM, then even that works fine.
Can, or has, anyone else added large jpegs to a sequence to see it's impact on exporting?
Anyone else with a GTX690 using GPU acceleration?
Anyone else with 2x GTX690's, or any other nVidia card with 2GB of VRAM, using GPU accerleration on exports?
The "slowdown" I'm experiencing, with hindsight, does seem to be as if the video cards are not updating the screen but every 10-30 seconds. The CPU is not being utilized very heavy at all during these times. But I have to wait the 10-30 seconds to see where my mouse has moved or what has updated on the screen. As soon as the export is finished....everything is back to normal. Or...if I just choose 'software only' on export, everything works fine and fast, and I experience no slow downs during export.
Can anyone point me toward a list of effects that are handled by the GPU during either previews, exports, or both?
My cards are in the officially supported list for Mercury Playback Engine....but I've also already tried deleting the .txt files listing the supported cards....and this didn't change anything.

JSS1138 Feb 10, 2014 8:47 AM (in response to cpachris_1969)Scaling is accelerated, and is the most likely culprit with such high-res images.
