After Effects CS5 (MAC, german trial version) needs 5-10 minutes to start up, hangs on the message "MediaCore wird initialisiert". On another Mac (small macbook!) it works fine. I did a reinstall, no effect. No plugins are installed.

Thanks guys.  It looks like both of you are having a similar problem with a third party AVI codec.  Please remove or uninstall any third party AVI codecs such as DivX,  XVid, etc. from your system and try AE again.  

You can also temporarily disable these components by closing any QT related apps and then dragging components out of the Library/QuickTime folder on your boot drive.   If that works, try adding them back one by one until it fails again.  That is the problem codec.

Thanks for your help figuring this out.. and for the beer offer. Don't think  I'll be in Dresden any time soon, but if you could recommend a brand I'll give it a try here..  hoist a virtual toast as it were 

Just for the record, this would appear to be caused by the Perian codec for Mac, correct?  Which version was causing this problem?  Thanks.

Anyone else still have QT32 Server related problems on this thread?

This worked for me too Seth.  Thanks for solving the issue!  AE CS5 is running beautifully smooth now.  My 'AVI Importer' file was dated 2006.  Don't know which numeric version it was.

One of the best german brands (beer) in here is called "Radeberger". Sorry for offtopic and just for my interest: where are you and are you really able to buy german beer there?? Cheers 🙂

Oh, forgot: I had the latest perian installed (don't know the version yet, but it was the latest one).

This particular QT32 Server problem is only about third party QuickTime codecs. Are you still having a hang problem on AE startup that matches the three criteria listed in a previous post?   Are you on Mac or Windows?

You would have non-standard QuickTime codecs only if you either:

- installed them yourself  (like the Perian codec), or

- they were installed by side effect when you installed other video applications or hardware

Seth no this was not caused by the Perian component (for me anyway). It was an AVI Importer component.... I have also had problems with After Effects on other computers and these problems were caused by bad fonts on my system so I suggest to others to check that if they are having problems too...

I installed the CS5 demo of AE on an 8-core 3.2GHz Mac Pro running OSX 10.6.2 and couldn't believe the ridiculous startup time.

I just want to say that I'm glad I finally found this thread (after searching multiple variations on Google).

Following the advice above, I narrowed the culprit down to a QT component: AviImporter-r7 (Intel).component

I am not sure where this component originated, but perhaps that will be useful for someone else knowing the name?

Hello 8rik, hello everybody,

I'm working on a Imac 3.06 Ghz Interl Core 2 Duo / 4 Go 1067 Mhz RAM / OS 10.6.4

AE CS5 failed on demo and final version due to the Adobe qt32 server process.

On my computer, impossible to find the "AviImporter-r7 (Intel).component".

Where is it ?

What to do ?

Adobe support is not able to help me or fix the problem...

The Mac path is :

Library > Quicktime

I erased : AviImporter-r7 (Intel).component AND XviD_Codec-r58 (Intel).component

Both were 4 years old (2006 !)

IMPORTANT : just renaming the files is useless / erasing the files makes AE CS5 work in 5-10" instead of 2-6' !

"think i have the problem since win10."
I'm not surprised -- AE CS 5.5 was released 5 years before Win 10.  Things have changed.

I'm running AE CS5 on Windows 7 (64 bit). The program worked fine for months but is now hanging up on start up during the Initializing MediaCore sequence. It takes about 5 minutes to launch the program and when it finally does I get the following error message:

You have at least one output module template that refers to a missing output plug-in. Please check your Output Module Templates.


It seems to have lost the Quicktime codec and now will not recognize any files in the Quicktime format.

See this document:

http://kb2.adobe.com/cps/857/cpsid_85711.html

That document talks about aggressive firewall settings, but we've also seen that some other software (like FileMaker) can block the TCP communication that these components require.

If I'm right about what's causing the problem, the QuickTime failure is because After Effects is being prevented by some software on your computer from communicating with the Adobe QT32 Server process.

I am trying to run Adobe After Effects cs6 on windows x64 bit , but it still hangs at "Initializing MediaCore." This is a huge problem in my schedule and I need a quick solution.

I have tried so far:

- Removing all third-party plug-ins

- (I would have tried this but for some reason I do not have the "QT32 Server" file in my task manager.) Attempted to delete QT32 Server

- Closing program completely, restarting computer

- Giving the program almost 3 hours to load

None of these "solutions" had any effects as I was still hung out on the Initializing MediaCore Screen

Please help!

Also, whenever I click on the loading image for AE, it says the program is "Not Responding."

Could this at all help?

MacPro 3,1

OSX 10.6.8

AE CS6

QT 7.7

Same here, except on Mac. Restart after a complete freeze, then upon startup AE hangs on the "Mediacore" status message.

I've tried the following (one at a time):

  • Reparing permissions on the main drive.
  • Starting up AE as the only application running after a restart.
  • Trashing preferences.
  • Turning Mac firewall off completely.
  • Making excemptions for AE CS6, dynamiclinkmanager and Adobe QT32 Server in the Little Snitch rules, making an exemption for AE in the Mac firewall setting (was unable to find dynamiclinkmanager and Adobe QT32 Server applications to pinpoint to).
  • Removing all Quicktime components in the Library.

The only thing that gets it going is ending the Adobe QT32 Server task. Not a valid solution because evidently I will want to be able to render using Quicktime!

I have a faint memory of having had this problem with CS5 some 1,5 years ago. - Does anybody know what I did then?

Very frustrating. Especially on tight deadlines!

Fast help very much appreciated!
