Rendering problem in Vegas Pro 20 when using Color Grading

Dave-B wrote on 9/27/2022, 3:42 PM

I just upgraded to Vegas Pro 20 (version 20.0 build 139) from Vegas Pro 18 and I have encountered a problem not present in Pro 18. When using fairly aggressive settings in color grading I get a diagonal line of various colored pixels when rendering the timeline. While rendering, it is visible in the preview monitor and in the final rendered file. It is not visible while editing. The source material and final rendering format make no difference. Hardware or software encoders made no difference either. As you can see in the attached snapshot, this 8mm film needed some fairly aggressive color grading. Specifically, I was using the Auto Color Levels feature in this case. The Auto White Balance and other adjustments in color grading have less obvious errors, but they are still there. As previously stated, this did not present itself in Pro 18.

Are you using Intel Graphics? What is your driver version? It is a known issue and I can add your information to a support ticket I made a while back.

In the meantime, turning OFF "GPU Acceleration of Video Processing" in Preferences->Video should help.

Intel Grahpics (UHD 630) or software rendering have the same result. I'll try your solution tomorrow.

Right. That setting doesn't affect rendering directly. It affects the processing pipeline.

Please post your Intel 630 graphics driver version. I can't add to my bug report without it.

Also see if Vegas will update your graphics driver for you. It is in the Vegas Help menu. Mine won't because the driver is in Asus jail.

Graphics version 26.20.100.7925. No updates available.

Thank you.

Added to my bug report.

Here is my workaround.

That's a very old driver for the Intel UHD 630 (latest ones start with 31.). While Vegas can't find newer Intel drivers, Intel can. Try the Intel Driver and Support Assistant tool and see if it helps.

My computer apparently will only allow me to install drivers provided by HP (my computer brand). Something about being tied to the vendor. I’ve searched the Intel web site. I see no versions of the graphics driver much beyond what I have now, certainly nothing starting with 31. Do you have a link to the newer drivers?

Hi Dave, does HP not have any newer driver than that available? (though they are notorious for not updating drivers- remember that from my Envy laptop).

It is possible to install an Intel reference driver over it. I did that with my Dell.

Nothing new available from HP. I'll check out those Intel driver links when I get home from work. Thanks!

My brother recently found that out with an HP laptop he bought not all that long ago - and he's not happy and is now looking for another brand. He even had problem with Windows updates which went round in circles because of HP's control over what can and cannot be updated.

@Dave-B

There are 2 types of drivers. DCH (generic) and non DCH often used by OEM. You cannot simply update from one to the other. You need to uninstall the driver first and then you should be able to switch to the other one.

The latest intel driver from the manufacturer website (Acer) for my laptop is from 2017.

Yes.

He would most likely have to uninstall his OS, wipe his hard drive back to the stone ages, and install a new non-OEM operating system. At least that's what my Asus would require in order to update the graphics driver. NO, I cannot uninstall it and reinstall anything else.

There is some encouraging indication that the Intel 620/630 acceleration bug (official bug report) may be better in a future update.

Until then, turning OFF "GPU Acceleration of Video Processing" should get him through, as it has for me for the past two years...

When I switched to generic drivers 2 years ago I uninstalled the OEM driver, installed the DCH one, checked a box from Intel saying that it overwrites any OEM specific features and that was it.

To go back to OEM drivers you need DDU uninstaller to delete all traces of the DCH driver.

For my HP I had ended up with hacked AMD drivers to get one that would be recognized by Vegas. Very annoying.

Update: I managed to upgrade to the latest graphics driver version available from Intel (31.0.101.2111). That made no difference. The problem persists. Unchecking the "GPU Acceleration of Video Processing" option in Vegas Pro 20 did indeed solve the pixelation problem, but rendering times with certain CPU-intensive plugins is unbearable. Specifically, I have a short :15 clip of a Super 8mm film transfer I'm testing with. Aside from color grading, I use the Neat Video noise reduction plugin which is very CPU intensive. That's the bottleneck. With GPU acceleration enabled it takes 1:30 to render with the pixelation problem. With GPU acceleration disabled, it takes over 4 minutes to render with no pixelation problem. That's waaaaaaay too long. I hope a bug fix is available soon or I'll have to revert back to Vegas Pro 18 and ask for a refund for the "upgrade" to 20. 😖

I've copied your findings to my original bug report to the developers.

I'm disappointed that this bug was not fixed in the new build. *sigh*

Intel UH630 has frequently updated its driver.

I upgraded to 31.0.101.2111 shortly after my original post.

I ended up reinstalling my copy of Vegas Pro 18. The bug does not exist in that version. I guess I'll continue using 18 until the bug in 20 is fixed.
