    A Sequence that played back fine last night is now giving the EXCEPTION: Unable to Get Format Descriptor.

    It will not even load into the Source Monitor.

    This seems to be the latest in a string of problems with this Project.

    The original Clips were from the Sony FS7, so they needed to be AMA Linked and Transcoded.

    One day, the Clips went off-line.

    They were all brought back in and now this.

    I find this is usually a problem with the link.

    Try deleting the linked clip from your bin.

    Then simply just go build the link again from scratch.

    Quite often i find even without deleting the link, but going through the motions of linking the clip, it will show up on my timeline properly after avid sees what drive i’m looking at…without actually clicking on the file for a link…it just needs to reprocess that folder structure.

    PITA, but it seems to correct itself easily enough.
