Preparing Audio in Media Encoder - so many files

Hey folks. I just updated to the new 2019 Creative Cloud. I am encoding my first project since the update. When I export out of Premiere, everything appears the same and completely normal. When I am in Media Encoder, everything seems normal as well. When I hit Start Queue (green play button) It tells me that is has to prepare 3611 audio files. I don't even have 3000 assets in the project. I literally have no idea where to begin to triage with this project.

One thing I did was to start a new project, then imported the project I am working on into it. My thought would be that it would properly index the project files, eliminating any sort of issues. What it did was reassign many of my audio files. I have to go beck, use Replace Footage, and reassign most of the audio. Why, I don't know. When I went to export out of this new project with the old project opened in it, Media Encoder tells me the same thing - Preparing Audio (x of 3611). Then it just chugs away at preparing this magical 3611 audio files.

What went wrong and how do I fix it? I don't even know how to properly ask so as to search through the forums or FAQ.

Thanks for your help.

I FIGURED IT OUT! At least it worked for me. 

 

I was editing in Multi Cam and when I go to export I had the same issue with it taking FOREVER to 'Prepare the audio' 

 

What worked for me was switching the Multi Cam setting from 'Enable' to 'Flatten' 

 

BOOM problem solved. I hope this helps someone. It was extremely frustrating for me

How is your audio encoded in your source media?

They were Zoom files and for whatever reason media encoder took a long time to process each one. Solution was to combine all into a single WAV file in the sequence and ditch the Zoom files.

This is absolutely still happening. I have 2 audio tracks and it is preapring 167 of them. Takes about 20 minutes of wasted time.

Same here...  I have a series of shows made from a larger collection of media all in one project.  When I export a 12-minute show it "prepares" 18 audio clips and takes about an hour.  Show renders in less than 10 minutes.  I read somewhere that it can be caused by mixing audio sample rates (e.i. 44.1 sources with 48 output or vice versa), so Premiere is converting all source audio each time?  Has anyone experienced this?

Any luck on this situation?

Having the same issue. Literally exporting video reframed with one audio track of about 20 seconds to test it and it runs through several hundred preparing audio bars. Never been an issue before a few weeks ago but is seriously slowing things down now. Tried clearing things and even reinstalling and it's still happening. Once audio is done video takes a tiny fraction of the time, seems to be about the video processing speed I had before this issue so not sure what happened to the audio. Help?

Yep, having this issue too. It does go slowly through the first ~12, then super fast through 13-44, then slow again on the last one. On this render, I also can't select hardware encoding as an option, so maybe that's related?

I have the same problem as well. Every time I export anything in Media Encoder it takes forever "preparing audio" before it starts encoding the video. Here's a screenshot of Media Encoder during export of a video with only 4 audio tracks:

 

 

And of those 4 audio tracks, two of them are empty. If there's any way to fix this, please let me know. I'm on Premiere Pro version 14.2.0 (Build 47) running on Windows 10.

Having the exact same issue. Not only does it prepare hundreds of audios that are not even being used within my "in" and "out" points, but it does it for every single file in the queue. So it is probably preparing the same audios that it just did for the last file.
Very time-consuming.

I have a nearly identical problem.  I am exporting a video clip with 2 audio tracks and 2 video tracks and in Media Encoder it says (Preparing 46 Audio Tracks) and also starts chugging away.  I experimented trying to export a 1 second clip and it did the same thing and crashed before it even finished preparing the 46 tracks of audio (of the 2 actual tracks I have).  VERY FRUSTRATING . PLEASE HALP

Did anyone ever get an answer for this? I have the same thing happening in 2020.

I've not seen this before. How many audio tracks do you have in your sequence?

 

Have you tried creating a brand new project and importing your original project in it's entirety, then trying to export from there?
