thank you so much for your response.
I’ve not made myself clear. The issue is that many of my .MXF files have gone missing out of their folders within the overarching contents folder.
so although the sequence of folders (and my own memory) point to the fact that the video clips were shot, many of the folders are empty.
See the uploaded picture. In the AA00330 folder (for example) there’s no MXF file.
i never deleted them, so at a loss as to what could have happened.
