Yes, but there's no need to do that in Vegas anymore. I'm using Vegas Pro 22.250 and the audio transmitted through Vegas is correct. I assume that in Vegas 23, this correction is also unnecessary.

Yes, I know, but the question also applies to the new Voukoder, because it seems that Vegas is sending a lower quality image to Voukoder than to other encoders --> https://www.vegascreativesoftware.info/us/forum/what-format-does-vegas-send-data-to-the-encoder--149851/

I understand, old versions added 0.44ms as I read, but Pro doesn't add anything?

Quite old, probably from 2 years ago.

So, as I understand it, the encoder "tells" Vegas what format it needs? And what about rendering to AV1? I'm asking because I'm having trouble sending the full-range color range to the encoder. In the Vegas settings window, the Color Range field doesn't seem to work at all (in the case of Voukoder).

Does Pro also add some time?

What video format does Vegas send data to the encoder, specifically Voukoder? RGB, YUV? 8-32 bits? Rec709? Limited range or full?

[…] Try rendering the audio separately (to WAV) in Vegas, then combining it with the original using ffmpeg. The audio will then be as it should be.

Probably so. It might also help to note that I rendered just the audio to WAV in Vegas and replaced it in the rendered file with Voukoder, and now the audio matches perfectly.

I've noticed that since Vegas 22 (build 250), the program no longer offsets audio, so clips rendered with the old Voukoder now have an audio offset -- the audio track from Voukoder has almost two empty frames added at the beginning @ 50fps. I'm writing because the problem may also affect the new Voukoder.
