Slight stutter after rendering but only if H.A. turned off

I am using the PD15 Trial (through the Director Suite download). I've been testing the product encoding using the SAME frame rates trying to reduce the number of variable to a minimum for the best output. Perhaps if I purchased the product I could install driver updates but I cannot so trying to figure this out the best I can. So with the Trial, some output formats/fps/size settings have Hardware Acceleration checked while others do not. Using the same format I found that when it is enabled there is no stutter at all. At the slower rendering there is always a bit of stutter. Before, during, and after I have verified my frame rates and they are always the same whether I use 23, 24, or 30 fps. I've tried Custom as well and the stutter is still present BUT only with non-Hardware Acceleration enabled.

So does anyone think this is a hardware issue? I've gone through most, if not all, the threads on PD15 on H.A. and I couldn't find another with this issue. BTW: I am using a brand new AMD Threadripper 1950X Nvidia 1080ti 32GB RAM system running extremely well with XMP 2.0 enabled for peak performance with temperatures across the board well below the max on all cpu cores so hardware should not be the issue.

{jealous} How does PD15 utilize all those cores/threads? Saving up my $$ for Threadripper. Editing should be really smooth. Intel i7 4770k, 16GB, GTX1060 3GB, Two 240GB SSD, 4TB HD, Sony HDR-TD20V 3D camcorder, Sony SLT-A65VK for still images, Windows 10 Pro, 64bit

Buy it...BUY IT NOW!!! You will get rendering performance like you have never seen before! The deeper the timeline...the further utilization of cpu cores and gpu cudas! So GO FOR IT!

Thanks, sounds like a dream machine. As to the suttering, I seem to recall some users have posted that using HA caused some issues. I have GTX1060 , but haven't seen any issues. However, I don't push the software like other users. Intel i7 4770k, 16GB, GTX1060 3GB, Two 240GB SSD, 4TB HD, Sony HDR-TD20V 3D camcorder, Sony SLT-A65VK for still images, Windows 10 Pro, 64bit

hmm, that XMP could be an issue. Overclocking RAM or your CPU has the potential to corrupt data in memory. A perfect situation for that to occur would be when rendering videos, especially if it's software rendering only. I would turn off XMP and see if that makes a difference.

As for PowerDirector settings, I know the encoder has some limitations with the trial version. For instance, I think the full version allows for "high profile" h.264, whereas the trial only has "baseline" and "main" profile. Whether that would make a difference, I don't know.

I appreciate the reply and comments. I've tried both ways with XMP off for the bulk of my rendering. Made no difference. Yesterday I spent time and tried every setting in the Settings as to cpu acceleration with graphic acceleration as well using the original PD15 build and the very latest 2820 build (installing this latest build was a bit of a challenge to install as the Trial version doesn't allow newer builds...only paid copies of the program). No difference. Same with different formats too. No difference. I had well over 20 produced files when I was complete. Just crazy. It is clear something is causing it and I might just have to continue to use H.A. on everything I do from this point forward. The difference shaves off a few percent time-wise so with H.A. multiplied by eventual very long renderings would be worthwhile. But I would have thought the studder come from the faster rendering not the slower one. So much for logic here. It is tossed out the window! David L

I think you are on to something here! I used what you said and tinkered a bit. And it has to do with something CyberLink posted that if you don't have GPU capable of H.A. then H.A. is not supported in the Trial. So the stutter goes away when you use non-H.A. with MPEG 2 output...but not some others. Microsoft's format seems okay too! I did not document which ones but its rather interesting. In this day and age GPU's should be powerful enough to render a lengthy or 'fat' timeline so who cares if Cyberlink turned it off. It can still be tested. I suppose without getting into technicalities YMMV!

Thanks! I will continue testing. David L
