What kind of footage did you use? I tried it yesterday with a large 70 minutes project, that rendered ~3h20 (just do delete the result) and made me aware of this problem. Today I rendered a small XAVC-S UHDp30 project with no filters and got the result shown on tp with the hedgehog. Then I just took one of those clips and rendered with my ‘old’ favorite (see on top).

It is absolutely reproduceable here and disappeared after replacing the folder.

The one, that you already used from the RX10 M4 should be quite similar to mine.

Here one more frame with this problem

The very strange thing and this makes it very unlikely that the input decoder (compound dll) is causing this problem is that during rendering the preview window shows the correct video.

Now I‘m not sure, that replacing this FileIO folder is a real workaround. I started rendering my current large project and assumed the PC would be working a while. Now that I checked it, I saw an error message “An error occurred creating the media file xxxx. The reason for the error could not be determined”. Nevertheless a short MP4 file with about 1min46 was output. Which is surprising for me, because the MP4 finalization normally starts when encoding is done and on my lager project this takes some minutes.

I’ll give it another try staring directly after rebooting.

Thank you. On my system the problem is only visible in the output file. Preview and render preview are OK.  So what could be the differences?

...So what could be the differences?

You have i7-6700K with Intel HD 530 graphics, and Cornico has i7700 with Intel HD 630 graphics, right? That's one difference.

I thought he would also have the i7-6700k. But I'm using a quite old Intel driver, because my system had standby problems with the newer. So I will test to install the actual from the 7th November on my testsystem.

Hmm, can't reproduce the issue on my ASUS X550V laptop here.

Render to Intel HEVC, using 1080-25p template settings.

Q: How do you able to set the Profile into Main@L5@High ?, I found mine is Main@L4@High, and in customization, I only have 'Main'...

According to this list you are right.

In the meantime I got the latest HD530 driver ( Version: 15.60.0.4849  Date: 11/7/2017 )from here

https://downloadcenter.intel.com/download/27266/Graphics-Intel-Graphics-Driver-for-Windows-15-60-?product=88345

and installed it on my test-system SSD (same system).

The render results are the same, but with this driver my monitor gets waked up about every 25s when the system is in standby mode with the monitor to be switched off.

This might be the reason, you can not reproduce the problem. As far as I can see, there is no user selection for the Profile. It seems to be set automatically by the encoder  according to the requirement.

Update: Finally found how to encode in L5 - render in 4K resolution.

*After this recording, I test put back the HEVC-rendered media to the VP15b261, and so far I see - no issue.

Let me try with the Runner's stock footage above.

To make reproduction more easy, I have uploaded you one of my original RX10 M2 UHDp30 clip that I shortened to ~10s to render. And the result HEVC file.

My Computer is not fast enough to playback the 4K HEVC footage.

Here's my render test of the Runner's Sample footage. Try play it on your system.

It looks OK. Did you encode using Intel HD530 QSV with the latest driver ?

Asus X550V uses Intel HD 630

This might make the difference. Cornico with his i7-7700k can also not reproduce the problem.

Hi

Working okay here with an Intel i7 7700K to the Intel HEVC at 4K. This is using driver version 15.47.02.4815 dated 10/10/2017 on Intels website. The latest version dated 11/7/2017 which is version 15.60.0.4849 which now supports UHD is definitely broken, as on my dual monitor setup I get terrible banding on images like it's using a much lower colour depth just on one monitor, drag an image over to the second monitor and it displays fine, no problem on any of the older drivers.

Note: 10 bit rendering using Intel HEVC still broken!

Regards

Phil

Thanks, would be nice to read some thing from an i7-6700k user with latest Intel driver.

@Peter_P

I have rendered your videoclip to exact default setting as your template (having gpu set to intel in the general video preference). I do not see any artefacts, video plays and looks fine. My 8700K has an Intel UHD 630 with the latest intel driver. Render time was 1 minute and 54 seconds.

@bitman

That indicates, that QSV is not active on your i7-8700k system. The rendertime to HEVC UHDp30 should not be more than F=1.4, as it is on my i7-6700k.

I assume, you can select the 10bit HEVC render option and rendering will take about the same time ???

That is what happens on my system, when I switch off the internal GPU.

Interesting that QSV would be not active, I will check further tonight, I am at work now.

Thanks, I was also looking at the i7-8700k to replace my system.
