Lower the audio sample rate of your Vegas project and try again. AAC has a limit of 96 kHz.

Can you enable low-level logging in your Voukoder options?

Tried your settings in Vegas 20 with the same version of Voukoder, and it works . . .

Always stops on frame #102? That's odd. Do you have "Render Loop Regions Only" set in Vegas render options?

Can you elaborate on what you mean by the render "freezing"? Do you have to force-close Vegas, or what?

No errors that i can find in the logs. Maybe somebody else can see something. The fact that it's rendering at all is puzzling.

The AAC codec in FFmpeg used to have a bug that would glitch on anything over 48 kHz sample rate, although i thought that was fixed years ago. Did you try 48 kHz?

Also, maybe try changing video and audio formats, see if you can pin the error down to some specific setting or format.

Does VoukoderPro give you the same problems?

Does it render without using Voukoder? Or using Voukoder but software rendering, like x264? Are your video drivers up to date?

Yes VoukoderPro works fine in Vegas 21. On the other hand, Voukoder 13 predates Vegas 21, so possibly there are some issues there?

When you install VoukoderPro, you have to manually select your NLE (Vegas 21, etc.) from the setup menu. This is not automatic. Seems to confuse a lot of people.

In the Vegas "Render As" menu, make sure you have "Show Favorites Only" de-selected.

If neither Voukoder nor VoukoderPro works on your rig, there's something screwy with your system settings. Lots of successful users with Vegas 21.

Your vRender times are 100x higher (slower) than mine.... and my system is not new. Some of your vRender times (the time Vegas takes to render the frame before it gets fed into Voukoder/VoPro) are over 1 second, which is bonkers. On a system like yours, I'd expect at least double-digit fps . . . not <1 fps.

[20:02:18] Frame #49: vRender: 798341 us, vProcess: 0 us, vEncoding: 3036 us, aRenderEncode: 906 us, Latency: 802295 us
[20:02:19] Frame #50: vRender: 1071685 us, vProcess: 0 us, vEncoding: 4496 us, aRenderEncode: 566 us, Latency: 1076763 us

Are you trying to run any other programs at the same time (e.g., mining?), or is Vegas running out of RAM? To be clear, you're saying that all projects malfunction, without exception? Have you tried creating a simple new project and rendering that?

I can offer a known good benchmarking project that works in all versions of VEGAS 16 and newer: https://forms.gle/d9zdQkFgkD5D2FLYA

If it doesn't work there's a problem with the installation or system.

Similar problem here, after updating both VEGAS and Voukoder to newest versions.... just rendered succesfully after changing project settings audio from 192000 (the original resolution of the WAV file I am using) to 48000... also 96000 would work.

48000KHZ sample rate is standard for video editing.

So Voukoder is attempting to render at 192000? What audio format are you rendering to? AAC? Not sure what the allowable maximum is.

Quote from Joe24

AAC has a limit of 96 kHz.

Mystery solved, mostly likely- unsupported values chosen for the render format.

Not sure if users can be warned when such settings are chosen?
