I think some audio issues get mixed up here:

• Audio option not available in Voukoder
• Audio option is available but there are sound issues (or no sound at all) in the exported file

fayfen Can you try https://d.voukoder.org/voukoder-9.3.msi

Does this version fix the audio sync issues?

https://d.voukoder.org/voukoder-9.3.msi

The visibility of the audio- and video option in Voukoder depends on VEGAS settings (In case you want to export video or audio only).

So if the number of audio-tracks in the VEGAS settings is 0 that option will be hidden in Voukoder.

What are your audio settings in VEGAS? Can you make a screenshot?

Please post a voukoder logfile (with debug info) from such an export session and I'll take a look at it.

P.S.: You can download older versions on github: https://github.com/Vouk/voukoder/releases/

I installed the RayOff theme. You can switch to it in your account settings.

Please upgrade to Voukoder 9.2. It should fix the sound issues with After Effects.

Voukoder 9.2

1. Basically export speed is the reason. If you export a yuv420 (8 bit) it is significantly faster to use the 8 bit output mode in resolve. Otherwise each frames data has to be converted from yuv444 16 bit down to 8 bit first, and then sent to the encoder. If resolve delivers 8 bit already we can just pass it through to the encoder.

2. It is a bit tricky because it just shows the available containers that support the current selected audio and video container. But I'll see what I can do.

Can you tell me the steps on how to reproduce this issue?

It would have been helpful if you'd have reported this issue when you noticed it in the RC. It is fixed and will be available in 9.2.

I might do it, but there are no plans when to do it. Don't expect something soon.

Make sure you are using the latest connector for your application(s). For using NVENC (SDK 9.1) encoders driver version 436.15 or later is required.

Can you test this version?

https://github.com/Vouk/voukoder/releases/tag/9.1rc1

Thanks, I'll have a look at it next week.

Did you also install the main Voukoder software "Voukoder 8.0"?

https://www.voukoder.org/forum/thread/783

The issue is this entry in the AfterFX export dialog:

It basically tells Voukoder: "Yes, this export should have an audio track." But it never actually sends audio data. Voukoder then waits (forever) for the first audio data so that it knows when to send the container header. This got introduced with the "tmix" change. Not sure how to solve this ... I might have to kick out the "Change FPS" filter, which makes more or less also the "tmix" filter useless ...

If you set it to "Audio Output Off" it is working fine.

As there are some issues with this release I have removed it for now to find the reason for the instabilities.
