CUDA acceleration does process some things differently. You'll need to create your graphics with CUDA turned on so you can adjust appropriately. That means in PP, not AE.
Or, just turn CUDA acceleration off.
Jim, so you're suggesting that I create my graphics in PPro instead of AE? That's not going to work! I must be one of the few people out there that output AE files with an alpha channel and import them into PPro, for I can't imagine Adobe not addressing this if many people were using AE & PPro together in this fashion. I guess I'm stuck having to continue to use MPE in software mode only (alpha channels work perfectly in this mode, but I have to do a lot of rendering.). I used to blame Matrox for this problem. Sure glad I haven't upgraded to a Titan!
BTW, I get the same undesireable results in MPE Hardware Mode when using Dynamic Linked Comps to AE.
One last question: does the quality of the video card make any difference with this alpha channel problem I'm having with MPE? I'd buy a Titan card right now if that would solve my problem!
No. The processing is the same regardless of the card. The only difference the card makes is speed, and the Titan probably doesn't offer sufficient improvement to justify it's price. (At least not where CUDA acceleration is concerned.)
I'm curious if leaving GPU acceleration on and doing a "Sequence/Render Entire Work Area" would fix this. If it does, then this would likely be a faster render than the render required for software only.
Jim, good suggestion. I tried it and the rendered Timeline looked idetically bad to the unrendered Hardware MPE mode Timeline. Interestingly, the time to render didn't seem to change when MPE was in Software or Hardware mode.
There are a plethora of settings in the NVidia Control Panel. Does anyone know if one or some of these settings may be affecting the MPE Hardware mode performance, or lack thereof in my case, that I've been getting with AE alpha channel files?
They won't make a difference.
