I'm not sure if I can understand you. What are your exact questions?

Right! You need a license key for your copy of Voukoder Pro.

Please post the Voukoder Pro log file or a scene test result from the designer app.

This belongs to an old Voukoder (non-Pro) installation. Use the uninstaller to remove it.

Maybe I need to configure the installer that a reboot is necessary after the installation.

Uncheck this setting here:

Yep, works! Now save the scene to a name. And select that scene name in your NLE and do an export.

I don't have much experience with the Microsoft Foundation encoders, but it seems to work on your side, but the muxer can't write it. Maybe you can try a more standard encoder and muxer?

So, you now have ...

• Voukoder Pro
• FFmpeg (I can see the Scene Designer starts up and encoders are visible)
• You licensed the product (In title bar of the scene designer it says "Registered to <Your name>", not that it is unregistered)
• You deleted your scenes.json file and Voukoder Pro has created a new one after restart

That's good and sounds like it's supposed to be.

Now create a first simple scene in the Scene Designer by clicking Scene > Create > Simple and save it to the name Simple.

If you now perform a scene test... what happens? Please paste the output here.

Did you try to reboot your PC?

I'll work on fixing it. Please don't use any unicode chars until then.

There are several issues here:

• The log file is from the "old" Voukoder app, not from the pro version.
• You'd have to get a license. Voukoder Pro is now a commercial product.. Please go here to get one.
• The incorrect values may happen if you have tried a very old version of Voukoder Pro a long time ago. You can fix this by going to %localappdata%\VoukoderPro and delete the scenes.json file. Note: All you saved scenes will be deleted!

Licenses are offline validated. I have no control over single licenses.

Set your wanted file name in davinci.

In the scene designer keep it like this:

2025-01-29 15:53:37 (error)    [OutputNode.cpp:199] Unable to open output: Hunger at Home - Prores
2025-01-29 15:53:37 (error)    [Router.cpp:161] Open phase failed: -11

Did you configure a custom output file name in your output node?

Try using the default file name, don't override it. It must have a valid absolute file path, file name and file extension, 'Hunger at Home - Prores' is not valid.

It seems there are permissioning issues with your target directory.

Can you try to export it to you desktop only?

Please rename it to 2025-01-29_15-53-36.txt and try again.

Can you try one of the latest FFmpeg installers and see if this has been fixed there?

• FFmpeg.GPL.Installer.msi
• FFmpeg.LGPL.Installer.msi

Please also perform a scene test and check the log results in there.

Just select LIBSVTAV1:

I've added the log file extension.
