Hi,
I've got a firmware update today and now I can't render anymore !
Error message : "An error occurred while creating the media file xxxxx.mp4 - A component failed to initialize."

I've tried to download again Vegas 23 (356) from my account and install again, same issue.

What can I do ? I've an important and urgent render to make.

After opening Vegas Pro 23, I see that there is indeed an update to build 356.

Two things:

which render template are you using; and
from your Signature, your NVIDIA GPU driver is around 16 months old - try updating to the latest NVIDA Studio driver (though NEVC problems caused by 591.44 - apparently with any VP23 version).

For VP 23 it won't work with older NVIDIA drivers (probably due to an SDK update) but should work with one that's 570.XX or newer. See if that helps.

Alternatively do non-NV Encoding render formats work? MagixAVC with Mainconcept, QSV, or ProRes?

If you need to go back to an older version they are all here. https://www.vegascreativesoftware.info/us/forum/faq-where-can-i-download-vegas-pro-and-other-vegas-software--104782/

@Dexcon 591 works fine in VP23. It's the older versions of VEGAS (22 and older) where 591 causes a problem.

I've tried to uninstall and reinstall build 356, same issue.
Installed build 278, works fine.
How to send informations to Vegas Support to identify what is wrong with 356 on my computer ?

I don't want to update Nvidia, new software updates are sometimes worst as old, proof here with 356.

Sometimes you MUST update the driver if the software you use requires features that were added in a newer version of the driver. 591 works fine in VEGAS Pro 23. If you have older versions of VEGAS too, you might update to version 581 instead which will still work with 23 as well.

I think it's just an old driver issue, my laptop also couldn't render using NVENC with a 560.XX driver and now can render with 581.57.

Should I use Nvicia App to update driver ?

That's how I did it. Alternately, you can download it from their website.

Updated NVidia to 591.44 and Vegas 23 to buid 356 and it works 😁
Rendering is now much faster 50>80fps

I had previously the NVidia Gamer driver, I've installed the Studio driver

Thanks@all
