Didn't hear about this issue anymore with the latest version.

For all future reports of this issue. This is a generic error message if something/anything is not correct. Most likely an incorrect encoder or an invalid parameter of it. There will be a better error reporting in the next version 3.0! Please send a Voukoder Pro Logfile or a perform a scene test and copy the log here.

I don't have access to the 2020 version of After Effects anymore, but with the 2025 version its working:

It depends on the implementation. ChatGPT explains it like this: […]

This has been added.

That's not how it works. Please run either the GPL or LGPL installer MSI file. It will copy the files to the right location and do also the required additional steps.

What FFmpeg libraries / package(s) did you install?

Please try rounding the value to 2S as I asked above. I don't know if FFmpeg rounds it down to the nearest integer value.

Ah, maybe the thousands of this value is correct. Can you try 2S (2 Samples) (as it is actually 1.98912S) for 48KHz?

Correct! But don't forget the uppercase S at the end.

It's the return of this issue. It's a VEGAS bug, not a Voukoder Pro bug. The audio is delayed by 0.0444 seconds (Vegas Pro: Audio Shift in rendered video [URL:https://www.voukoder.org/forum/thread/552-vegas-pro-audio-shift-in-rendered-video/]). Voukoder Classic added a hidden filter with this specification: (Quelltext, 12 Zeilen) This is not present in Voukoder Pro anymore because the filter chain has been entirely reworked, but you can add a filter after the audio input node: This is…

Currently this is not possible. But it's on my list to finish this for the 2026 release.

Some older versions had issues with the "profile" option. I had to update my FFmpeg to fix that issue.

Are you using the latest version of FFmpeg?

It should be all in lower case.

FFmpeg is working fine. Otherwise the designer app wouldn't work properly. Please copy & paste the log file here: %LOCALAPPDATA%\VoukoderPro\

Important: I'll stop distributing the old version of "Voukoder" and its Connectors by the 2025-04-30. If you want to keep the installers, start making backups of it now. The version will (most likely) continue to work.

It is most likely your nvenc config of: (Quelltext, 1 Zeile) contains one or more params or values that are not supported by the 3070 TI. NVIDIA and the FFmpeg developers sometimes add parameters and values that are only supported by the latest version of their GPUs. Unfortunately it is not possible to show you only options that are supported by your system.
