I need to make H264 HD & SD stereo versions from my program master that has 12 Channel split track audio created in AVID. I want to just use the first to channels of the master which is the stereo mix. I know that choosing the Quicktime format allows you to choose the source channels 1-2, but the H264 format doesn't give that audio option. I've tested the export to H264 and it sounds like it's exporting just the stereo mix rather than a mixdown of all the tracks. Is there any way to confirm this? Or is there a way to edit the source tracks from the master file in AME? I know I could export a Stereo version of the master from avid, but I'm trying to avoid the extra step. I'm currently working with AME 2019. Any knowlege or advice would be greatly appreciated. Thanks!
