    Some weirdness when linking media

    I just want to see if this is my system.

    On MC 2018.12.3, I'm having some interesting AMA linking issues. I've got an XAVC-S file (MP4) linked into a bin, but the file location is not the one it's supposed to be (I was having some issues, so I copied the file to a different directory and used that). The current directory ig G:\New Folder (this is supposed to be a temporary thing). The location of the original folder (and where the file also exists) is G:\Vacation 2016\XAVC-S\card1_7-8-2016 (Yes, I am editing vacation video for the family). It's the same file name (C0015.MP4).

    I renamed the file in New Folder to something else, and then did a relink of the master clip. It did not relink. I linked the original file in the vacation folder in a new bin, and then relinked the sequence using selected items in open bins. That did not relink.

    Here's the fun part. When I do a get info on the both of the master clips, they both point to G:\New Folder even though I most definitely linked to the file in the Vacation folder.

    I renamed the AMA Manangement folder and tried again, but with the same results. Then I deleted the master clip from the bin and linked to the one in the Vacation folder. And again, it selected the one in New Folder.

    I'd like to see if this is reproducible. A simple procedure:

    1. Take the same media file and copy it to 2 different directories on the same drive.
    2. Create 2 bins.
    3. Link to one of the files in the first bin.
    4. Link to the second file in the other bin.
    5. Do a get info on both master clips. Do they point to the same file?

    Re: Some weirdness when linking media

    I created 2 directories on a different drive  drive J and copied the same file to both directories,  After linking to the J drive with the Avid Generic plugin info still points to my O drive where I originally copied them to.  When I link with the paid nablet plug-in to the files on the J drive info points to the file location as J the correct drive.

    Re: Some weirdness when linking media

    OK, I figured it out on my system at least. Look in the Avid AMA Mangement Folder (should be C:\Users\Public Documents\Avid Media COmposer\AMA Management\AMA Metadata Folders\projectnameXXXXXX where xxxxxx is a string of hex digits. See if there is an AAF file in there of the same name as your linked file. Rename it to something else, and then try linking again.

    Re: Some weirdness when linking media

    My understanding is that when you first Linked the file Avid stored various info about the file, including a UMID from the file. This is stored in the AMA Management folder as you discovered. When you make a Windows copy of that file, the copy has the same UMID as the original. You can rename one of the files but it still has the same UMID. That renamed file will link again with the original name. You get other strange behaviour when you have copies as you found out. When you deleted the AMA Management AAF for the file things started working again. AMA Management can be disabled in Setting > Link.

    Re: Some weirdness when linking media

    The file ID is only the same within the same volume. This is for two copies of the file on 2 different volumes, hence two different file IDs.

    The issue here is why did this one file, out of many hundreds of linked files, end up with an AAF in the management folder when none of the others have. That's the part I'm trying to discover.

    I am seeing the UMID carried across volumes here. User scocklin's post looks like it shows the same thing.

    I have a file, NAS3File.mov (PRHQ), on a NAS mounted as N:. I copied the file to a different NAS mounted as X: and renamed it to NAS2File.mov.

    I <Alt> drag Linked the Original file from N, NAS3File.mov, to an empty bin. First screen grab is of Get Info, bin and console

    I then <Alt> drag Linked the Copy from X, NAS2File.mov, to a different empty bin. Second screen grab with both Get Info, both bins and console:

    Both bins have a Master Clip named NAS3File.mov and both Get Info's show the source is NAS2File.mov on the X: drive.

    That does sound strange. On the machine I just tested on (MC 2018.12.5) the management folder has AAF's for almost 300 Links going back to the clean install of MC 2018.2.

    Re: Some weirdness when linking media

    This is getting evern wierder. Quite a lot of my linked files have AAFs. Quite a lot don't. Operationally it doesn't seem to make any difference.

    The UMID is an avid thing (I'm pretty sure it's supposed to stand for Unique Media ID).

    I am seeing that too.

    Have you seen this help pop-up? That may explain it.

    I'm not sure it's just Avid but yes, Unique Media ID.

    Most of our Linking is QT mov's and wav files. A wav with bext data (Broadcast Wave) also has a unique ID and will also cause Linking problems if copies or renaming is involved. I don't know if other files carry the unique ID's that will copy across volumes.

    Re: Some weirdness when linking media

    File IDs do not copy across volumes. Apparently Avid's UMID does.

    BTW, I do have linked media management enabled. Somewhere along the way, something did something funny, I don't know where. I don't know when. I certainly don't know why. But at this point, as long is it all works, I don't think I care. I have to get back to editing.
