Thanks for the reply, I assume you mean that even if I use a 3OA input it simply encodes it to the 8+2 correct?
When selecting the Matroska preset you can't choose a .tbe as input, as of FB v3.3.3, there are only spatial workstation 8 channel, 1st, 2nd and 3rd order ambix as valid audio inputs.
Unless I have to mux the .tbe with the video afterwards...?
