Preparing Audio in Media Encoder - so many files

[Galaxy_Sailor]

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.

For anyone still running into this issue in 2023, I did as well and I have the SOLUTION🙌🏻

just copy everything on your current timeline to a new sequence, and render from the NEW timeline, my media encoder is flying through my renders now.

I hope that helps, gang!

For anyone still experiencing this issue, I created a new post documenting my troubleshooting of this bug. It has returned for me, but maybe something here will help you: https://community.adobe.com/t5/adobe-media-encoder-bugs/quot-preparing-audio-quot-is-taking-too-long...

Hi there,

I encounter the same issue.
I've got a 96kHz sound, unfortunately, but my Sequence settings are correctly setted up to 96kHz, and I created special sequences for it, as it must be -> it solved the issue of endless "Preparing audio files" at the beginning of editing, even if I finally exported in 48hHz (wich is the limit of Premiere).

But the problem came up again, and I can't solve it now by any mean found on this forum.

For my short film, Media Encoder is rendering more than 600 audio files each time I launch an export, even if it concerns a few part of the editing...

My final sequence is made of subsequences, but the problem's still the same when I'm trying to export from one subsequence (with the number of audio files included in).

Even rendering audio from the Sequence tab before the export doesn't work for me.

And I can't "flatten" because I'm not working with Multi-cameras.

I suppose the problem's linked to an incompatibility between the 96kHz audio source files and the 48kHz output... ?

It's very frustrating and time-consuming, but the problem seems to be unfixed from 2014 at least, according to this forum.
