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

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-claims-to-be-processing-hundreds-of-audio-clips/idi-p/14028654#M1069

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.

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!

This is still happening to me. Adobe/ Media Encoder, Please look into this.

Another way that worked for me was simply creating a new sequence and copying the timeline assets over to the new one and exporting from there.

I've tried a LOT of different things and this just worked for me nearly 2 years later. Thank you for this.

I had AME (Media Encoder) "Prepairing Audio" forever and also finally crashing before the export was done. AME started to go through more than 500 audio files and my current export had only 3 of them. Yes, this was part of a bigger project, with probably >500 audio files, but I only wanted to export a small part of the whole movie and AME started creating problems with it.

I found a solution that worked for me:

1.Copy only the part of the movie that You want to export (select all you want to export with mouse on the Timeline and click Ctrl+C).

2.Then, create a new empty sequence: (File->New->Sequence) and paste the part there (Ctrl+V)

3. Now, use the normal exporting commands in Premiere: File-> Export-> Media and do your export settings

4. Click "Queue" to export via AME

5. in AME: go to Edit-> Preferences -> General -> Video Rendering and change the "Renderer" to "Mercury Playback Engine Software Only".

6. Wait. It should now work flawlessly.

I assume this could possibly be partly an issue with the amount (lack) of memory in the computer and also with the so called "playback engine". All computers seem not to have full capabilities to do this kind of exports via their "hardware engine" so it is worth trying to select the "software engine" instead in the Preferences. Maybe that one uses less memory and for some reason also does not go through the hundreds of audio files when selected.

Sorry, instead of "Wait" I meant: Export.

If anyone is still having this issue - particularly when going from premiere pro to media encoder - then simply mute all tracks that you are not using in your render. If you have many audio layers then leave them unmuted and shift your other audio clips onto a lower layer(s) and then mute.

Media encoder will ignore the files on muted tracks.

I've tried some of the remedies listed here to address this problem, but it is really something Adobe needs to address. In my case, I have a single timeline with numerous short excerptsd that have been extracted from longer videos. No multicams or anything like that, just one video/one audio track. To export as a batch, I set the workbar to the boundaries of each video segment to be exported, and load them into AME one by one. Then, when I start the queue, it 'prepares audio' for every single audio clip in that timeline, despite the fact that only one clip is part of the actual render. If I need to export forty files, that means it goes through this process 1600 times, that is, it processes all 40 audio clips, for every single one being exported. There should be a preference to set audio ONLY to be 'prepared' for the exported work area on the timeline.

Fast forward to 2021 and this is still happening. I was doing a quick compile of 14 bits of archive footage (whole tapes) on a sequence, do some cropping and field de-interlacing and then export them individually to H.264. Just marked each segment and sent them to Media Encoder. Yes each one started to "prepare" 14 audio tracks. The sequence is almost 12 hours long so this was literally going to take days.

The solution is to make a subsequence (shift+u) of each segment, rename the new subsequence and send that to Media Encoder. Then Media Encoder only prepares the audio in the subsequence.

So if you just want to export a short section of a long edit for approval or something make a subsequence first.

Thank you. That did the trick for me as well.

Now can someone at Adobe please pass this on? Premiere should be smart enough to 'flatten' multicam clips on the fly when exporting.

SOLUTION! I've had this same issue. It happens to me when I have a very large project, and keep adding into it without deleting old files. Once I cleaned out my project I saw a significant reduction in how many audio files needed to be prepared regardless of what I was exporting. Hope this helps!

agentchillb, what do you mean by deleting old files? I am currently having this issue with a large premiere pro file that includes zoom audio files. Please please help me.
