Re: [Avid-L2] Help for audio files quarantined with CM_INVALID_TRIM error

I've identified the source of most (perhaps all) of these errors I've
been experiencing.

I can repeatably generate the problem (CM_INVALID_OFFSET error and
quarantining of audio files) by importing .wav files via AMA, and
consolidating them. Crucially, Avid will only quarantine the new audio
files if they are consolidated in a project for which 'film options'
have been selected during project creation.

(It's worth noting that this appears to be a bad workflow for other
reasons as well. When I AMA-import .wav files, the start timecode field
is always 00:00:00:00, whereas the files get a proper start timecode
assigned if they are imported the old-fashioned way.)

I've attached more detail below, in case anyone wants to try to
reproduce the problem.

Project type 1080p/23.976 WITH film options (35mm 4 perf):
-----------------------------------------------

- import .wav files via AMA, and consolidate them to an empty MXF/1 folder
-deselect 'skip media files already on the target drive'
-check all audio conversion boxes to 48kHz/16 Bit and PCM (MXF)
-choose "Keep masterclips linked to media on the original drive."

Files consolidate succesfully, but Avid generates the following error before creating the .mdb database in the MXF folder, and crashes to the desktop after choosing 'continue':

Assertion failed: iofRefNum != 0
/Snapshots/relengsnow6_1343949798/coresw/core/Projects/Mac/../../src/filesys/coreMacFileLocator.c,
Line: 1586

When I restart Avid, I get the CM_INVALID_ERROR / Quarantine dialogue before even selecting a project.

If I select 'Ignore all' at the Quarantine prompt my consolidated audio stays online (so the newly consolidated masterclips will play inside Avid). If I choose 'Quarantine All', all the newly consolidated audio is moved to the Quarantine folder.

If I 'Ignore' rather than quarantining, any future rebuild of the database in that folder will generate the same error.

Project type 1080p/23.976 WITHOUT film options:
-----------------------------------------------

Same as described above, up until the crash after consolidating.

However, on restart, the databases can be successfully rebuilt without triggering quarantine or CM_INVALID_TRIM errors. If I switch to a project WITH film options, I can still rebuild the database in this MXF folder without error -- indicating the problem gets baked in during the consolidation, not during the rebuild.
