Need help, Error code: 27

[graphicsc36062008]

Hi

I am using HP Z840 workstation (Xeon E5-2680 v3 @ 2.5Ghz / Nvidia Quadro K6000 GPU / 32 G Ram / Win7 64bit ) and Premiere  11.0.2(47), AME.11.0.2.53

While trying to export a sequence as Quick Time format and H.264 as codec, am getting this error :

Many thanks in advance.

I believe QuickTime is not installed in your machine, and you tried to use a QuickTime H.264 preset that you previously created.  QuickTime is needed to encode with QuickTime H.264 codec.  However, Windows version of QuickTime is no longer officially supported by Apple and could pose some security concerns (see Apple Ends Support for QuickTime for Windows; New Vulnerabilities Announced  ). 

I recommend using MP4 H.264 format instead.  You can technically still install QuickTime and use H.264 codec.  But, please understand possible security risks that's associated with Windows QuickTime.   If using Mac is an option, you could use Mac as it is not affected by this security concern.

Thanks MMeguro

But Quick Time was already installed.

In Media Encoder and Premiere Pro, do you see H.264 listed under the "Video Codec" option in the QuickTime settings?

You may want to try uninstalling and re-installing QuickTime Player.

Yes. I have H264 under video codec option.

I already tried uninstalling and re installing Quick Time player. but didnt help

I checked the spec of your PC.  It seems your PC has more than 16 CPU cores. Unfortunately, Windows version of QuickTime from Apple doesn't support 16+ CPU Cores (including HyperThreading) for H.264 encode.  As Media Encoder relies on QuickTime for QT H.264 encoding, Apple needs to fix this problem on their side, which is unfortunately unlikely as Apple no longer supports Windows QuickTime.

One possible workaround is to reduce the number of CPU cores used in your PC.  You can disable HyperThreading or some CPU cores so that the CPU core used in OS doesn't exceed 16 cores.  You should be able to change CPU cores in BIOS settings.

Hope this helps.

Any way to get a DNxHD/HR render without turning off cores?

Seems silly to purchase horsepower you cannot use!

Hi @btyskowski

Are you talking about DNxHR/DNxHD MXF OP1a format?

QuickTime on Windows has an issue with H.264 codec on 16+ CPU cores, but DNxHR/DNxHD MXF OP1a shouldn't have an issue with high CPU cores.  Do you see a problem exporting to  DNxHR/DNxHD MXF OP1a format?  If so, could you create a new thread so that we can keep track of QuickTime issue and DNxHR/DNxHD MXF OP1a issue separately?  Then, please provide more detail of the issue you are seeing on the new thread.

Thanks,

Here is a screen grab of sequence setting that is giving me the error:

Thank you btyskowski.  I checked the new thread you created and now understand your issue (Error Code 27 ).  You meant exporting DNxHR/DNxHD source into Quicktime H.264.  Correct?  I thought you were tryin...I also posted my reply to the new thread.

Thanks,
