MC defaults to putting all files into MXF/1 until it reaches a certain number of files (I can’t remember right now) then flows over into a second folder MXF/2 etc. On some projects, I have started numbering my mediafiles at 10 leaving the first 9 for MC. So try the following (on a standalone system, not Unity):
Create a “10” folder in Avid Mediafiles/MXF folder
Copy MXF/DNxHD media to the folder
Launch MC, open MediaTool
Drag MXF files to bin
Check timecode at that point to ensure they are correct. This is what the system creating the media is inserting into the MXF file.
Open the ALE file and ensure that first frame of same clip is the same timecode. Perhaps there is an error in the ALE and not the MXF.
If correct, select clips in bin, go to import, set options on AL to “merge on known sources” (last option), then import ALE. All additional metadata in ALE that did not exist in MXF will now be attached to the files.
