Both encoder nodes are set to CUDA, as you can see in the following exported scene. Tried it both ways (CUDA / YUV 420).

temp scene v0.1.zip

When working with h.264/h.265 input in FFmpeg command line, I found I had to use h264_cuvid/hevc_cuvid instead of hwupload_cuda to avoid a similar auto_scale_0 error.

On the other hand, when working with uncompressed AVI input, I'd have to use hwupload_cuda and be very careful to feed it a supported pixel format (YUY2 in that particular case). See my command-line options in post #4 above for working examples.

Not sure what format the Vegas -> VoukoderPro link uses. If h.264, then h264_cuvid might work instead of hwupload_cuda?

In any case, something seems unhappy about the YUVA pixel format.

Hmm, can't get it to work. Rendering fails immediately with message: "Unable to start VoukoderPro: FFmpeg error."

Awesome news, thank you! I'm out of town on business ATM, but will try this out when I get back.

Make sure your Render As list isn't set to display Favorites Only.

The 'Scale' filter that is currently available does seem to use the GPU, but it's shuffling data back and forth to the CPU, very inefficient. Running 1 dual-output render in VoPro 0.7 is currently slower than running 2 simultaneous renders with Voukoder 13.

'ZScale' is even worse, as it doesn't seem to use the GPU at all.

On the other hand, the speed advantage of 'scale_cuda' should be substantial when it becomes available.

For reference, here are some FFmpeg command lines I've used for scale_cuda with AVI/h.264/h.265 file sources:

FFmpeg.zip

Properly fed, all 3 variants will max out the GPU encoder with minimal CPU usage.

An even more powerful feature of FFmpeg is the ability to use multiple graphics cards. Hopefully both GPU filtering (e.g., scale_cuda) and the ability to assign a job to a particular GPU will be added in the future.

NVENC VBR bitrate now confirmed working in v0.7.1.7, both with h.264 and h.265. Thanks.

Clearing the error can also be achieved by deleting the broken h.264 encoder node in Scene Designer and creating a replacement node.

Deleted scene.json. Realized this action had just wiped all my saved scenes. Downloaded and imported the file from my previous post. Will rebuild the other lost scenes from memory at a future time.

Scene Designer behavior unchanged, even in a fresh layout with a new encoder node. Render behavior also unchanged.

Update: This info is from the most recent VoPro log file.

Now it won't render at all (v0.7.1.6). When trying to render, immediately throws an error window that says "Unable to start VoukoderPro: Undefined error!"

Also, in Scene Designer, double-clicking on the top NVENC h.264 node (the VBR one, see preset below) will now cause Designer to crash. If you delete the node and create a new one, it will initially allow you to set the parameters, but if you try to access the node properties for a second time, it will crash Designer.

One other (unrelated) minor issue is that in the installer options, the Vegas Pro 20 plugin is deselected by default.

• 96kbps AAC confirmed working.
• Duplicate filename behavior confirmed working.
• I can't reproduce the different-folder bug now, even doing what I did before (Vegas destination was default Documents folder on C: drive, VoukoderPro destination was set to D:\temp). Not sure what the difference is now. Free win, I guess?

NVENC bitrate

• The 2 attached files are encoded using supposedly identical settings, one using Voukouder v13.0.2, and one using VoukoderPro v0.7.1.5. Both videos are 1080p and have a target bitrate of 2.5 Mbps. Screenshots of the settings used are included.
• Water videos.zip
• I'm not aware of any user-defined minimum bitrate setting for NVENC VBR in either Voukoder or VoPro. There are only target (average), max, and buffer bitrates. As mentioned, the max rate is being observed, but the actual output bitrate is much lower than the commanded target rate.

Audio confirmed working with VoukoderPro v0.7.1.4 and Vegas Pro 20.0 build 411.

A few issues noticed while experimenting with Vegas Pro 20.0 and VoukoderPro v0.7.1.4:

• NVENC VBR target video bitrate is not being observed, although the max bitrate seems to be working. This affects both HEVC and h.264. Didn't try AV1. Tried to set a target video bitrate of anywhere from 2500-512000 kbps etc., but actual output is 200-400 kbps. If 2-pass is enabled, things get even worse (< 200 kbps).
• AAC encoding setting of 96 kb/s CBR gives 128 kb/s. Other bitrate settings seem correct. This could possibly be an issue with the MediaInfo app.
• If Vegas' output file name and VoukoderPro's output file name are not in the same folder/drive, the render hangs.
• If you are creating multiple output files without specifying a unique name for each file, VoukoderPro will write both streams to the same file, resulting in a corrupt file.

Maybe you need to uninstall the VoukoderPro completely first.

Correct, v0.7.1.3 was still installed. Uninstalled both versions, reinstalled v0.7.1.4.

v0.7.1.4 is confirmed working here, alongside Voukoder connector v1.6.0.

Thanks!

Still broken here. But there's a workaround now.

So there is a conflict with both plugins installed?

Seems that way. Vegas Pro 20.0 won't load VoukoderPro if the Voukoder connector (v1.6.0) is installed. Haven't tried other connector versions. See my previous post for log file.

No it does not. Here's fileio_x64.log with both Voukoder and VoukoderPro installed:

fileio_x64.log.txt

In any case, uninstalling the Voukoder connector fixes things, and reinstalling it breaks everything again.

The string "VoukoderPro" does not appear in the log file.

vegas_script_x64.log.txt

EDIT: FIGURED IT OUT! Uninstalling the Voukoder connector v1.6.0 fixes the problem. Looks like you can have either Voukoder or VoukoderPro installed in Vegas Pro 20, but not both.

No.

voukoderproplug.dll appears in Vegas' Component list. Cleared cache and preferences using Ctrl+Shift. No change.

File size of voukoderproplug.dll is 175 KB, is this the expected size and version (0.1.0.0)?

Is there a way to log what's (not) going on?

Yes, voukoderproplug.dll is listed in Components (see screenshot).

Uninstalled and reinstalled Vegas. Flushed the plugin cache with Ctrl+Shift, deleted all preference data.

Still nothing showing in Render As menus.

No joy. No files left in the root folders this time though.

The file size on my voukoderproplug.dll is only 174 KB, while yours is 624 KB.

Regarding the installer: Can you test if this fixes the issue?

• VoukoderPro is still not available in the Vegas 20 render list. Tried uninstalling, reinstalling, rebooting, etc. Tried with the default installation settings, and also tried the options to install everything.
• VoukoderPro.aex no longer appears in the root folder.
• VoukoderPro.prm still appears in the root folder of a bulk storage drive (drive I:) which has no role in my operating system. There are multiple bulk drives available in the system, but it prefers Drive I:. If I remove drive I: from the system, VoukoderPro.prm instead appears in the root folder of my boot drive C:.
