Is powerdirector using NVENC instead of the older NVCUVENC in their latest builds? NVCUVENC supports CUDA, but according to Nvidia, the newer maxwell based cards support NVENC and are almost twice as fast as CUDA. The latest NVIDIA drivers only support NVENC, also my gtx860m maxwell based I7-4910MQ, 16gb ram, 256 samsung evo 850 pro, gtx-860m GPU

Yes, PD13 supports nvenc.
For older Fermi based cards and newer drivers, is still possible to copy the nvcuvenc files (3 files) from older nvidia driver and have CUDA accelerated encoding.
nvnc on Kepler is lower quality than the nvenc on Maxwell (750) and that is also lower quality than the one or Maxwell 2 (970/980).
Not sure what is the actual picture quality used in CL implementation. Since nvenc was mostly designed for gaming purposes, there are limitations.
Also, with nvenc on gaming cards, you don't have interlaced encoding - nvidia reserved that for Quadro lineup.

Thanks for the fast reply.
I updated my video card to latest drivers which supports NVENC, but it is much slower then when I use the older drivers with the older support....

Strange? I thought it was twice as fast, but it is half as slow...
Am I doing something wrong? I7-4910MQ, 16gb ram, 256 samsung evo 850 pro, gtx-860m GPU

Don't know, I don't have a card with nvenc. I am still using the old CUDA-based encoder (combined with newer drivers).
You can use GPU-Z to monitor utilization. For CUDA is the "GPU Load" sensor, for nvenc I saw it reported as "Video Engine Load" sensor.

On gpu-z is see on both sensors workload with latest drivers. Is cuda also used in NVENC? I7-4910MQ, 16gb ram, 256 samsung evo 850 pro, gtx-860m GPU

I think that CUDA it is used to 'help' nvenc:

I have emailed power director with the question if pd13 uses NVENC, and they replayed to me that I have to install AMD software :/ :/ :/ where can I find/how do I know that it supports NVENC? I ask this because I don't see much difference in rendering speeds when using the latest NVENC Nvidia drivers I7-4910MQ, 16gb ram, 256 samsung evo 850 pro, gtx-860m GPU

BTW, GTX860M exists in two variants - Maxwell and Kepler. You can tell by the number of cores, Maxwell has 640 and older Kepler has 1152.

I have the maxwell variant.
DoNic67; how do you know that pd13 supports NVENC?

Like I said, I saw reports that it works. In your case it seems that it works too. You didn't say what was the GPU utilization levels - you can do the test with the option selected and not selected.

Since you have a laptop, the bottleneck it might be in your HDD speed. Your system has to wait for the HDD to read and write back the data -for example a 5900rpm HDD is totally unacceptable. One 7200rpm HDD is slow.

For example, I have a desktop with 1 SSD (for OS and programs), 3 HDD tied in RAID 5 (for work space) and 1 eSATA external HDD to back up the data.

Hi, I have a 256gb ssd (850 evo pro), 16gb internal memory, i7-4910mq processor and gtx860m maxwell gpu.
Is it better that I install a second ssd for writing my projects to?
(One ssd for os and separate film clips, other ssd for writing the new mkv video file). Does 2 ssd drives provide better (faster) rendering?

And what do you mean with gpu utilization levels? (Sorry for my English, I am Dutch).

Thanks so far for all your help!

Editing videos on a SSD will wear it up really fast. SSD's have a limited number of writes on their sectors. Premium SSD like yours have only 3000 writes guaranteed. That's why I edit on HDD - there the number is in millions.

GPU-Z has a "Sensors" page. See there the utilization %.

Gpu load aprox 30% (25-35)
GPu video engine load aprox 65%

CPU load around 60%

This is with latest (NVENC) drivers

And with the hardware setting de-activated?

PS: I hope you have applied the last PD13 patch - even the beta mentioned on this forum.

Hi there,

i use version: 13.0.2307.0
what are the benefits of the beta version and where can i find it?

I will do a test run and post GPU-Z logfiles in a moment I7-4910MQ, 16gb ram, 256 samsung evo 850 pro, gtx-860m GPU

Here are the results. with and without HW-acceleration.
Source are mt2s files, 1080p 60fps, rendering to mkv 1080p 60fps.
it is a 2.40min project with only 1 effect included.

when i render another project with a lot of effects (theme designer foto and video included), i see on GPU-Z that there is hardly any HW acceleration...

Here are the result with a the desingner clip where all the video/foto needs to be rendered:
(clip is only 1.35m from m2st to mkv 1080p 60fps)

Strange things:

HW on:
GPU Core only 653 (instead of 1000)
GPU load: 5-40 (variable)
Video engine load: 4-20 (variable)

HW of:

GPU core: only 653 i(nstead of 1000)
GPU load 0-40 (ups and downs)
GPU engine load: 0%)

I will do a rerun with the old Nvidia drivers installed (337.8

Well, only SOME effects are GPU-accelerated. And those will use GPU CUDA regardless of nvenc setting (that's a different hardware piece).

Quote: Well, only SOME effects are GPU-accelerated.

But in the second run (file with theme desigener)GPU Clock speed is only 653....
Why not 1000mhz like when rendering the other file without effects?
