Hey thanks so much for responding. To give better clarity into what I'm actually doing, I am digitizing films I own and editing them to be able to watch them with my children. Sometimes removing a scene here and some language there makes all the difference. So I am bringing the remux'ed versions of 4k blurays with the audio converted from DTS to PCM 7.1 for premiere to read it. With the extra 2 channels I suppose I could merge those into the left and and right surround channels tht already exist. My question though is normally in premiere for example if you exporting via quicktime and not using the voukoder plugin you can tell the export what order the tracks correspond to what channels like in the screenshot I attached, but you cannot do this once you select voukoder. So what channel mapping order is voukoder using? How do I know what I have as the center channel in my premiere timeline isn't going to the left channel for example in my final export?
