Vegas Pro 19 KernelBase.dll error while rendering

Catherine-Ravenscroft wrote on 9/13/2021, 9:28 AM

Hi all!

I've been using Vegas Pro 14 for years to create YouTube videos, I recently upgraded to Vegas Pro 19 and unfortunately I'm just simply unable to get through a single render. Every time I click render the process starts and gets to a random % (Between 20% and 80% done) before firing off the following error message:

All of my project media is either MP4 MOV or PNG files so there isn't anything funky going on there. I definitely have enough space in the destination folder so that's not the problem either. I have tried both GPU Acceleration off AND on. I have tried Dynamic ram preview at any number of values from 0% to 75%. I have tried using Legacy HEVC AND AVC decoding in the File/IO tab. I have tried increasing and decreasing rendering threads. I have went into windows features and enabled Microsoft.NET Framework 3.5.1 and ticked the two boxes in there, I have ran the NET repair tool and no luck. I have ran various CMD options such as sfc scan and no luck.

My PC Specs are:

AMD Athlon(tm) X4 845 Quad Core Processor 3.50 GHz

NVIDIA GeForce GTX 1050 Ti

8GB Ram

All possible PC drivers are up to date.

I have attached my render settings and project properties settings to help out and would be happy to provide any further information to diagnose the problem.


Any help on this issue would be greatly appreciated. I have spent the past 4 days trying to fix this issue and its driving me mad 😰

Thank you all for any help you can provide!

When you say "all possible PC drivers are up to date", that doesn't necessarily mean you are using the version of the driver VEGAS needs. Nvidia GPUs have game ready and studio drivers, you want the latest studio driver, which you can find by going into the help menu and using the driver update utility in VEGAS.

Hi Fr0sty, thanks for the response!

I can confirm that I have the latest studio driver already installed as opposed to the game ready driver.

Catherine-Ravenscroft wrote on 9/15/2021, 10:13 AM

Apologies for bumping this but I could really do with some help. I've done a clean install of the latest NVIDIA studio drivers and it's still doing the issue.


Is there anything else I can do? I paid £279 for this software and it's not able to do the one thing I paid for it to do, I'm losing my mind :(

In Windows Settings, Display Settings, Graphics Settings, ensure there is an entry for VEGAS Pro and that it is set to the NVIDIA GPU...

In Windows 10 type "Graphics Settings" into Cortana, then click enter.  Set the menu to "desktop app" then click browse, and use the browse window to select the VEGAS program exe.  This will set up an item for VEGAS you can click on.  Click on the VEGAS icon and choose Options. Then choose a profile for the NVIDIA device on the system and click Save.

Catherine-Ravenscroft wrote on 9/16/2021, 2:19 AM

@VEGAS_EricD I appreciate the suggestion, it's one that I haven't found online anywhere,

I set an entry for Vegas Pro in the graphics settings as so:

but I just ended up with the same error while trying to render :(


Catherine-Ravenscroft wrote on 9/18/2021, 10:30 AM

Apologies for the double bump, but I still haven't been able to complete a render. I've submitted a support ticket 5 days ago and haven't heard back and I'm out of ideas/options :( Does anybody have any ideas?

fr0sty wrote on 9/18/2021, 11:27 AM

See if this helps... Disable GPU acceleration in preferences>video tab.

Look in the file i/o tab of preferences. Do you see the legacy decoders checked? If not, check them. If so, uncheck them.

Render your project, but be sure not to select any of the (nvenc) presets. Try one of the non-nvenc magix avc presets.

Do you still have the issue after doing those 3 things?

Don't sweat the double bumps, I know how frustrating it can be to try to get something done and the app not work right. We'll get you sorted, hang in there.

@fr0sty Thanks for the response, I've tried all 3 of these steps before, but for good measure I tried out a new render on a non-NVENC preset and unfortunately I got the following error :/

fr0sty wrote on 9/18/2021, 3:38 PM

You're still on build 361... there have been problems reported with that build and the development team is currently working on an emergency patch to fix those. In the mean time, please roll back to build 341, which you can find here:

Catherine-Ravenscroft wrote on 9/18/2021, 4:13 PM

@fr0sty Just rolled back to 341 and was hit with the same error 4% into the render, that was with GPU acceleration on however. Going to try again without GPU acceleration on, I'll update with the results! fingers crossed!

fr0sty wrote on 9/18/2021, 4:29 PM

Both your CPU and RAM are below the minimum spec for VEGAS 19, so that's possibly a cause.

Catherine-Ravenscroft wrote on 9/19/2021, 3:23 AM

@fr0sty The render failed again with GPU acceleration off, my friend has the same software running on an 8GB RAM, intel powered tablet laptop, and although it's slow it renders without crashing so I'm unsure as to why my PC doesn't want to play ball, I am planning to update my RAM soon but I dont see why it wouldn't work with my current specs, editing works perfectly fine on this RIG, it's just the render...

andyrpsmith wrote on 9/19/2021, 4:19 AM

Catherine have you tried different templates. If not try the Sony AVC/MVC and use one of the internet HD templates.

Also it it worth looking at some of the grovel files in the extra information directory (see your crash post for location) they open with word pad and may show any errors Vegas finds.


andyrpsmith wrote on 9/19/2021, 5:19 AM

My bet is that Fr0sty is right in that your 8GB of ram is totally insufficient. When I boot V19 it takes 7GB (of my 32) before you add anything to the time line. Could you fire up task manager and record the memory usage before you open V19 and then after and then a third reading after you add just one clip to the time line and play it. Mt bet is it is maxing out your ram. (do this with dynamic ram set to 0 and leave it at 0). Also record the ram usage from task manager when you add 1 or two clips to the timeline with a simple fade and try and render to see what amount of ram V19 is using at start of render.

andyrpsmith wrote on 9/19/2021, 5:25 AM

Look at mine with no clips and then just two clips with fade.

andyrpsmith wrote on 9/19/2021, 5:28 AM

Here is the RAM during render close to 10GB

andyrpsmith wrote on 9/19/2021, 5:32 AM

Just to note my CPU is below the specs at i5 3rd gen 4.08GHz but it works just fine and runs everything including AI.

vegas-pro-user wrote on 9/19/2021, 6:31 AM

a additional thought relating to hardware ...

with e.g. "HWMONITOR" you could check, if the CPU-temperature while rendering is eventually to high or so.

Catherine-Ravenscroft wrote on 9/19/2021, 7:24 AM

@andyrpsmith Hi! I appreciate your response! I've gone ahead and taken some screen grabs on what you've suggested:

Before Vegas is open:

While vegas is open:

With a clip in the timeline with a crossfade:

During a simple render of two short clips:

During a render of the project I'm actually trying to complete:

You can see that the ram is steady at 5GB usage in all the screenshots.

I am planning on buying more RAM at some point but I don't want to commit to that purchase until I've ascertained that the ram is 100% the problem, if for example I need a new CPU, I dont want to have already bought the ram, also I'm unsure as to why the ram issue would cause a crash? Especially since my friend has managed to complete a render of the same project I'm trying to render on an 8GB RAM intel laptop.

I've also checked the grovel files but have absolutely no ideas what I'd be even looking for aha 😅

RogerS wrote on 9/19/2021, 7:56 AM

I used the GTX 1050 (mobile) with 8GB of system ram for years so don't think either is the cause of crashes.

The CPU is from 2016 it seems, so not too ancient.

Can you get through the render of a sample benchmarking project here? Should work with VP 16+. See the form for instructions with screenshots:

Beyond that I'd do a reset of Vegas and clear the cache. Instructions

Catherine-Ravenscroft wrote on 9/19/2021, 9:55 AM

@RogerS I was able to get through a render the sample benchmarking project with GPU acceleration on. Here's the summary of the render.

The render went down to 1.1fps during the specified sections.

I used the following render settings:

However the sample project is only 41 seconds long, whereas my project is 34 minutes long. I can get through shorter renders without significant issues.

RogerS wrote on 9/19/2021, 10:11 AM

Good to know you can render something- if you couldn't even render this short promo video that would be a bad sign! Did you pick that frame size because it is what you normally use (720p)?

Any Fx you normally use that aren't present in this video?

Can you share mediainfo for the MOV and MP4 files? What camera or device created them?

Now the game is what's different that causes one render to work and one render to crash.


Catherine-Ravenscroft wrote on 9/19/2021, 10:47 AM

@RogerS I also use both 1080p and 720p depending on what I'm recording. I've tried again with 1080p and it took a bit longer but still was able to see the render of the sample project through.

So my project only uses a few different fx (VEGAS Flash and some fades in and out)

Media info for the MOV files, since they're all essentially the same thing I'm only going to include one here to save space but there are 12 of these MOV files.

The MP4 file was an OBS recording that was rendered with some PNGS over it using VEGAS, the MOV files were GIF files that were re-rendered as MOV files to make them easier for vegas to handle (The GIF Files would still crash when being rendered) doing so made the speed of the render 6/7x faster...

RogerS wrote on 9/19/2021, 10:54 AM

What plugin does Vegas use to read the mov files? Should say under properties.

What program did you use to make the gifs into movs?
