Do you have an example that I can download and try? I have the same video card and 344.11 driver on a W8.1, 4th gen i7 CPU

I just tried to test with a video I have and the HVAC was much slower -- almost 10 times as slow. I did not let either one complete and I just counted for the time.

I found this article interesting:

Here is a sample. Plays OK with my AMD FX-8350 (OC at 4.6 GHz) if I disable the hardware decoding for my 750 Ti. It uses about 53% CPU in task manager to play back.

I'm using PD13 build 2307 and nVidia drivers 344.65 .

If I turn hardware decoding on, PD craps out right around the time it shows the fireplace, and then shows blocky artifacts and stops.
When using GPU-Z set to update every 0.1sec, I can see the GPU load going to 20-50% briefly for the first couple of seconds, then back down to about 0. CPU usage doesn't go above 12%.

Note that you need to restart PowerDirector 13 when you change the hardware decoding setting.

The playback in your screen capture is not smooth actually, but that may be due to the screen capture tool, or the way you encoded the result. Which tool did you use for the screen capture ? I'd like to make a capture of the result here.

However, you have a GTX 550 Ti GPU . That card does not provide hardware decoding capability for H.265 (HEVC).
So, of course, you will not experience any problem with H.265 hardware decoding - there isn't any for PD to use .
If you go to the "sensors" screen in GPU-Z, you will see as evidence that there is very low GPU usage.
If you check task manager, you will see the CPU usage is very high, because there is no hardware acceleration, and the decoding is being done on your CPU.

I'm using a GTX 750 Ti, which does have H.265 hardware decoding capability . But there is a problem using it in PD13. That could be either an nVidia problem or a PD13 problem. I haven't tried to look for any other H.265 player, and I would need to find one that can take advantage of H.265 hardware decoding.

actually your set-up and mine are very similar, except I didn't OC my CPU.
screen capture program is called CamStudio 272 r 326.
yes, video was captured at 24FPS.

on the other hand you do have the Shadow Play which you can use for screen capture.
it's in the GeForce experience.

here's my earlier comp. set-up. yes I do have GTX 750Ti. someone gave it to me for 100 peanuts!
what I mean is I gave 100 peanuts for factory refurbished GTX 750Ti...
some lucky ones got it for 99 peanuts.

I do not have any hardware acceleration at all. it says but I don't think so.

I used trial version of div x converter to encode h.264 .mp4 files to h.265 .mkv and it was alright.
700MB file was shrunk to 90MB... noisy, too.

Your capture clearly shows in GPU-Z that you have a 550 Ti GPU, not a 750 Ti GPU .

Do you have multiple GPUs ?

Thanks, I will try that.

That explains it.

I don't install Geforce experience due to the unscheduled automatic driver updates which I don't want.

These threads are about hardware acceleration for encoding.
This one is about hardware decoding, ie. a playback issue.
They are separate problems.

I used trial version of div x converter to encode h.264 .mp4 files to h.265 .mkv and it was alrigh
700MB file was shrunk to 90MB... noisy, too.

I tried that, but I didn't have any luck with Divx software. The Divx player can't play the H.265 file I attached in this thread, even with the HEVC plug-in installed.

http://divx.force.com/apex/Show_DivxB2C_Article?id=kA1400000004NDg&language=en_US&url=How-do-I-enable-disable-hardware-acceleration-in-the-DivX-Converter

I tried that, but the Divx converter isn't showing this hardware acceleration option on my system.
I think it's probably because I'm using the 344.65 drivers which removed the CUDA encoder, NVCUVENC.
Divx converter is probably using this deprecated CUDA encoder. It must not have been updated yet to use NVENC on nVidia Kepler/Maxwell.

In any case, my issue is with playback here, not encoding.
The only GPUs that can do H.265 hardware encoding are Maxwell 2 - ie. the GTX 970/980 , which I don't have.
And that is only a hardware capability. I don't think the software stack supports it yet.
nVidia probably still needs to update the NVENC APIs to expose H.265, and then Cyberlink would need to use it in PowerDirector.

If I had to guess, this will work in PowerDirector 14 or 15, around the time the nVidia GTX 1000 or 1100 series will ship .

I'm glad that PepsiMan is providing helpful information.

I donwlaod the video and produced it to HEVC mp4 format both with hardware acceleration on and off. Surprisingly both took about 2:15 to encode and both used about 90% CPU.

They both played without hiccups but the software encode looked better. I expected that from past experience. The wood floor looked more uniform. With the hardware encode, there were shading patches.

I'm not sure I can add anything more. .

FYI, screen capture of the result done with Camstudio when playing back the H.265 file with hardware decoding enabled.

It's a 4K encode because my screen is 2560x1600 .

It also has CPU-Z, GPU-Z and task manager.

Without hardware decoding, all this fine.

The video I attached is already in HEVC format. You didn't need to re-encode it.
This thread is about an issue with playback of the HEVC, not about encoding. I have edited the thread subject to make that clear.

The issue won't show unless your GPU has H.265 decoding capability, like the GTX 750 Ti. You also need nVidia drivers that support it. I am using the latest nVidia drivers 344.65 .

Which video file? The last one at 4:27 this morning was the only one that show me the problem.

In that case, perhaps it would have been better placed in PowerDVD rather then the PowerDirector part of the forum.

I had already mentioned that I was using 344.11 so the later driver seems to be the issue. .

The first one, in the 3rd post on top of this thread.

I'm having a problem with PowerDirector, so I'm posting in the PowerDirector forum.
PowerDirector includes a media player, which claims to support H.265 .
That media player certainly should be able to playback the H.265 files that were encoded by PowerDirector itself.

I had already mentioned that I was using 344.11 so the later driver seems to be the issue.

Sorry, I had missed that. I will download and try 344.11 .
Are you also using the latest PowerDirector 13 build 2307 ?

Build 2123.

I missed that last update - perhaps it is a good thing! .

I don't have 13 anymore, but It plays with MPC having a 18% GPU utilization on a Fermi card. That with reduced GPU frequency (1/2)...

I just reverted to build 2123. The file plays fine.
However, the CPU usage is very high, and GPU usage is very low, even with hardware decoding enabled.
This leads me to believe that PD13 build 2307 added support for H.265 hardware decoding with Maxwell, but it is buggy.

FYI, I did not backlevel my nVidia drivers. I think the latest drivers are OK.

What's MPC ? Does it have a setting to enable/disable hardware acceleration ? If so, can you check if the GPU usage varies ?

My two 560 Ti Fermi cards are sitting on my desk right now. Don't really feel like plugging them back in this computer just to try.

They will likely end up in another computer of mine that currently has the very old 8600 GT / 9800 GT in them, which are no longer supported by nVidia. Hopefully I can find a buyer. I will do this hardware swap another day/night.

Nice. How old is yours ? Mine is a 13 year old male. He is extremely friendly, I have had him since he was a kitten.
Despite his weight he still jumps around the sinks and countertops pretty good. He just loves to drink directly from the faucets.
He is not afraid of water.

OT: My cat was abandoned, last summer it came in evenings at our door, hungry, and... we adopted him. It' probably 2 years old, a little skittish, but nice.
Has an embedded chip, but the previous owner didn't want to talk with us (on the phone) about it, it hanged up.
