A Happy New Year to you and everyone else, PepsiMan.

SoNic67 aka Grumpy, I tend to agree with your comment. It seemed like a good idea at the time but now I'm not sure what value there is in it. There are so many other variables/components that play a part in performance.

Happy New year to you and everyone else.
Yep Tony, maybe the next iterations of PowerDirector would take advantage of that possibility.
Because it doesn't look like this one did...

PS: Haha, Grumpy. Sure, why not?

I disagree, the tests, while limited, show to me that a faster CPU is not as important as a GPU that has the appropriate codecs build in and can make use of them.

For those with an obsolete CPU like me, money spend on a GPU like the GTX960 brings a much bigger video editing improvement than a much larger amount spend on a faster CPU.

Very likely, in most videos, about 90% of the time is spend in rendering the video stream.

Thanks for doing it Tony

Yeah, but at some point there is a brickwall. There is no difference between my 6core-12threaded and a similar generation 4core-8threaded at similar or higher frequency.

Once the CPU is fast enough to be able to "feed" the GPU adequately, then you can see that hidden bottleneck in action.

I got good results with a pair of EVGA GTX 980Ti FTW (SLI). Only one card is used during encoding.

Mind you those cards are about 2000$ CDN, mainly used for gaming.

Hello!
Guys I am new to Cyberlink software and I have some questions!
I have 2x nvidia 780Ti and i7 5960X cpu onboard.

Do I have to enable SLI to make two cards rendering work?

Is it better to use CUDA or enable OpenCL?

thank you

welcome to the wrong thread...

PD does not support SLI. supports GPGPU...

you don't have a choice, you must use current drivers and enable HA.

assuming you have the PD14 so do not ever install GeForce Experience. it's a crash city!

Somehow, I have GeForce Experience running since the beginning, and no crash for me.

I think it works ok only when you disable the NVidia screen capture option (ShadowPlay)

Guys thank you for your precious aids and sorry for the topic miss.

according to Cyberlink FAQ enabling OpenCL HW acceleration forces the OpenCL against the CUDA.

Your 780Ti is a Kepler based card that supports NVENC and is utilized in PD14 vs the older CUDA based encoder, pre Kepler cards and older Nvidia drivers. PD14 will use NVENC for hardware accelerated encoding when selected on the "Produce" tab or in the "Burn in 2d" module vs CPU encoding. As an additional option, you have the choice in pref to utilize OpenCL and the GPU to accelerate playback and encode of Fx applied to timeline as you refer. These Fx that are OpenCL accelerated are shown with the green Nvidia logo in the left corner in the Fx room.

Thanks!

Quote: so GPGPU does not need SLI to be active to use 2 GPUs full potential

Full potential, as in both GPU's doing NVENC encoding, not possible to my knowledge with any current or previous version of PD. WIN10 opens several avenues there but if/when it would really be supported by PD for basic timeline encoding, I’m not in the know. Two GPU support has been discussed multiple times in the forums but here was a recent PD14 look with demonstrated load shown on both GPU’s http://forum.cyberlink.com/forum/posts/list/45509.page#235018

No. Regardless of connection/setting I doubt that PD (and any video editor) cannot efficiently make use of multiple video cards at this time. As it is now, it cannot even use 100% of ONE video card, see the thread about the GTX 960 results.

Even in Jeff's test, one card was loaded at 30%, the other at 26%, it's like the actual processing load "split" between the cards at lower levels, to total the same value.

Quote: Even in Jeff's test, one card was loaded at 30%, the other at 26%, it's like the actual processing load "split" between the cards at lower levels, to total the same value.

Won't argue that the cards aren't utilized effectively, however, I totally disagree with the load "split" same value comment. Sure the load splits as both cards handle the OpenCL Fx preparation, but the throughput of using the two cards is very obvious as summarized below in a case for demonstration with PD14 v2302:

GTX960 with HA encoding, OpenCL for Fx utilized: encode time=1.00, GPU1=60%
GTX960 & GTX970 with HA encoding, OpenCL for Fx utilized: encode time=0.48, GPU1=45%, GPU2=45%

Encoding output is a default profile of H.264 1920x1080/60p 28Mbps

Overall encode time ~50% faster when more GPU compute capability available for Fx. Different timeline test case than previous so slightly different GPU loading percents, ~45% vs previous ~30% but benefit substantial for those who like lots of Fx's, not I.

Jeff

I said "like".
Obviously it works better, but not scaling perfectly, adding the 970 to the 960's OpenCL you should get an extra 3494 GFlops on top of the 2308 that you had (I assume single precision is used for effects).
I am not using effects that heavy either, so I didn't experiment too much with this.

Oh, well... it's confusing and complicated

HI Everyone wow this is a long thread, I actually started my own question yesterday about what would be the ideal computer spec for PD14. http://forum.cyberlink.com/forum/posts/list/47064.page
I did come across this thread but as it says it was more about the GTX960.

My question is: Would anyone be happy to conclude all of this information for a best "All round" "best value" spec?

Many thanks for any responses.

i have NX1 so even my system it does a decent job on 4K HEVC H.265.

i don't have i7 desktop(just a laptop Dell XPS L702X with i7 2nd gen) so in order to process 4K HEVC,

i needed either GTX950 or GTX960 with Maxwell GM206 cards which Hardware decode and encode H.265.

if you look closely, i've snuck in there my GTX 950 and GTX 750Ti data. hence the zeros and very long time to render

H.265.



if you go with GTX970(GM204) or GTX980(GM204) then my pick will be i7 Skylake cpus.

Skylake does HW encode and decode 4.2.0 8bit HEVC H.265. GM204 only HW encodes...

any other i7s then GTX950 or GTX960. to cover the all the bases so to speak.

also you've noticed that PD14 does not use full 2GB VRAM only around 800MB...



memory for the PD14, better stick with 16GB even though it only uses around 8GB.

have it and not needed than needed and not having it?



so for my system, i am the bottleneck and my system has caught up with PD; however, if you have a

killer machine then the PD will be the bottleneck.



happy happy joy joy

Thanks PepsiMan. I appreciate the advice especially on the CPU that I should be getting.

I have just spec'ed up a PC with: a i7-6700 Skylake LGA 1151 3,4GHz 8MB so this, with a GTX 950, 16GB RAM, 250GB SSD , Win 10 64 home, should be a reasonable set-up?

looks like one that got away for me.

if you can get 500GB SSD, then do it. that 250GB gets filled up real quick in my experience.

and 1TB to 3TB external drives for your work and backup.

yup, i second the GGRussell's comment that you should get the fastest CPU without

breaking the bank, then the GPU. i7-6700K or HK or HQ at the end.



check out the Julien's setup in this post -> http://forum.cyberlink.com/forum/posts/list/46535.page

Julien has assembled to have both pcs do HEVC H.265.

for now buy the GTX960 or GTX950 for your system. why?

for me, i am waiting for an intel cpu that'll fully process HW 8/10bit 4.2.2 HEVC H.265 later this year!

i do not know the projected prices for new cpu, though.
