For starters, I'm running Premiere Pro 14.7.0 and Media Encoder 14.5, and I've attached my sequence settings, export settings, source file audio properties, and my audio effects applied to my audio tracks. I'm not sure if all of this is relevant, but I've included it just in case.
My issue is pretty much summarized by the post title. When I export my sequence in Adobe Media Encoder, my audio is about -6 db quieter than in my project sequence. But when I export (with the the same settings) directly through Adobe Premiere Pro instead, the audio is exported as is in the project sequnce.
This is the first time I've experienced this issue running Premiere Pro 14.7 and Media Encoder 14.5. I've been using these versions for the past month with no issue.
Do you have any idea what could be causing this? Is it just a bug? Am I doing something wrong?
I'd love some help as I would hate to sacrafice my editing capabilities in turn for exporting directly through Premiere Pro.
I can see a couple of problems right away, but still need better info from you to fully diagnose the trouble.
In the first instance, you are mapping stereo files to dual mono outputs - this is not good, you should have a stereo master output set up to begin with, which will give you a stereo interleaved output.
New Sequence Settings
You've also got a mono Multiband Compressor set up on Audio 1 - this should be treated with the same caution as a loaded shotgun as these are tools it is very, very easy to get completely wrong. Can I see the actual settings of this please?
Moving right along, why are you using Rectified Waveforms? This tells you next to nothing and should be changed to waveform display by clicking on the sequence hamburger and adjusting as below
Changing from Rectified Waveforms to regular
If you can post the Multiband settings that may help, but I would definitely start again, setting the main sequence to a stereo master and adding audio tracks as needed in order to output a proper stereo mix.
