Which Program build?

18 Build 527

Which processor?

Ryzen 9 3900x

Which GPU?

RTX 2060 Super

Which exact driver versions for GPU('s)?

Version 461.92

Which codec is used for rendering?

I have tried a few. Some using the graphics card to render and others without.

-XAVC S Long

-MAGIX HEVC/AAC MP4

-MAGIX AVC/AAC MP4

HERE are screen shots of the settings/preferences and one of the crash-data I keep getting (it doesnt crash every time, sometimes it just freezes at 5% or 20%):

Thanks, untill now I cannot find anything not good or unusual.
Is it 4K or UHD you are render-to?
And are you able to show here screenshots of Options/Preferences/Video and Options/Preferences/File I/O ?

Yes I just added a DRIVE link to my original post at the bottom with screenshots. Thank you!

The video is 3840x2160

Next time you can upload screenshots here:

Anyone able to help? I ended up breaking up the rendering the 24min video into 4 parts. So 4 separate 6min renders and then taking those new renders and putting them into a new timeline and rendering all 4 files for the complete 24min video. Even doing that, while rendering each of the 4 separate videos, Vegas crashed multiple times and after re-rendering I get lucky and it works.

Have you already worked through this troubleshooting guide?

Chris-Fix:

Have you looked at the temperature(s) of your CPU while it is doing the rendering? I built a new computer with a fancy-schmancy powerful CPU, but found that renders on complex (lots of tracks, plugins, etc.) projects would hang in roughly 4 - 8 minutes. In my case, the CPU was getting hot, in the low 70's (degrees C). Although the CPU wasn't causing the PC itself to hang or crash, Vegas 18 Pro obviously didn't like it. I have an ASUS motherboard, so I used their Fan Xpert Windows utility to crank the CPU and case fans to max before I start the render - now the CPU stays in the low 50's and my renders finish. So what's the moral of the story? I found that video rendering is VERY stressing to a CPU, and can cause its temps to go high (quickly). Maybe the CPU throttles when it gets hot, and Vegas doesn't know how to handle it - I can't say; but try "extra cooling" and see if that helps.

I will check it out. My buddy has a different setup and I gave him all the files and he tried rendering it on his setup and the same thing happened. At a random % it just froze or it crashed right away. Thanks for the idea. Still waiting back from the Vegas customer service tech people to see what they have to say as well.

Are you using the NVENC or Mainconcept render with MagixAVC? I'd try both and see if you get through a render. I wouldn't render to X-AVCS, it's a bit uncommon for that purpose.

(Looks like you are doing this but for NVENC encoding try setting dynamic ram preview to 0MB. That helped me with render freezes.)

Other than that your Vegas settings look fine. There is enough space on the c:\drive for temporary files and the render? [Edit, see you have 300+GB free. That should be enough.]

Which settings did you use with the sIII? It has a variety of recording formats.

More workarounds: if you have to chop it up and render, try rendering to Apple ProRes and then put the renders into a project and combine them. Vegas works well with that format and it's good quality.

You can also have Vegas send frames to Voukoder to render. The x.264 modes are space-efficient and fairly quick to render. voukoder.org/

@Chris-Fix Try disabling HW decoding in the I/O tab.

I'm having exactly the same issue in Vegas Pro 19 on a laptop (LG Gram). I know, not even close to a content creator pc.

I have 48 minutes of 3840x2160 30fps video to render.

At first, I created the project with 4 hours of raw footage that I stretched down, added some texts and transparent colors. Impossible to render.

Then I rendered it in 9 parts, and it worked. Now I just want to put the 9 together in one: impossible!

I could get to 84% in 3840x2160 30fps (after almost 3.5 hours), but it completed in 3290x1850 30fps (3 hours of rendering).

Memory tops at 67% of usage, but the processor is at 100% no matter the resolution I choose to render, with very little help from the integrated GPU.

I thought my laptop was not powerful enough, but if the same problem happens on a beast like that of Chris-Fix, I'm starting to think there is something else going on.

I'm redering higher resolution (4200 x 2160 30fps) projects with effects (Continuum, Moca masks, etc) with no issues, though they are much shorter.
