  Assertion failed Error message when trying to play certain clips in a bin

  Posted by Jackie Tyler on March 25, 2016 at 12:39 pm

  I’m running a project on V8.1 on a 2015 MacBook Pro that was started on a PC. I’ve copied some of the media onto a portable drive and most of it plays and works fine but certain clips, when I double click on them to try and play them give me this message:

  Assertion failed: (pChoiceNode)!=0
  File:
  /Snapshots/relengmtnllon3_1406253623/coresw/ame/src/ColorManagement/ColorTransformationXmlFactory.cpp,
  Line: 142

  The weird thing is, is that I can play the clips within the bin in script view and pressing play on the thumbnail, it’s only when I try and view it in the composer window that it gives me this message.

  Any theories on what’s going on?

  Any help much appreciated!

  Hi Jackie

  You’ve probably forgotten this now but I have the same problem – did you ever manage to fix it?

  Thanks Anton

  Are the clips your having issues with AMA Linked or were they imported or transcoded to MXF OP Atom files.

  Either way quit Avid first and then navigate to your Avid MediaFiles/MXF folder. In there you will see at least one numbered folder and in each numbered folder there will be two files named msmFMID.pmr and msmMMOB.mdb. Delete these files and then start Avid up again, if there’s a lot of media it may take Avid a bit of time to rebuild those Databases.

  This may not help but I’ve suggested it because the Databases PC’s build are not completely compatible with the Mac Version of Avid and Vice Versa. I’ve fixed many issues by deleting these and letting Avid rebuild them in the past including playback issues like you are having.

  If they are AMA Linked then make sure you have the correct AMA Plugin Version installed on your system.

  Hope this helps.

  Hi Anton, did Brent’s advise work in your case? I am facing the same problem.

  Many thanks

  Dear Brent,

  I followed your advise and deleted the files you mentioned. However, the error message still appears. In my case, it is not linked to any particular bin, clip or sequence. It appears everywhere once I open the project in MC. I am using the 8.1.0 version with a Mac Book Pro OS X version 10.9.5.

  I would appreciate very much any advise to solve this.

  Many thanks!
