I've been using Media Encoder to render my Adobe Premiere sequences and up until yesterday, I never had a problem with it. Out of nowhere, it won't render more than 2 audio tracks. The audio plays fine in the timeline preview in Adobe Premiere, but when I render it, some of my audio is missing! I have no idea what could be causing something like this!
I'm rendering in h.264 at Youtube 1080p 29.97 settings. I've done this for all of my previous videos and haven't had a single problem having 3+ audio tracks until the last two videos I've done
Sometimes a project can be weird/corrupted and do strange things. Then you need to outsmart the computer. For example, try an audio-only export. Create a .wav file and import back into project, and if all tracks are properly represented in that mix, add .wav to timeline, mute all other audio tracks, and do your final AV export using that new audio.
