FCPX 10.1 Media tracking

A geeky post for video editors…

While working on my FCPXchange utility, I did some experiments to see how well Final Cut Pro kept track of files if you moved them around under its feet. I was quite impressed with the results:

Now, exploring a bit further, later, I realised that it can’t be using Spotlight, at least not exclusively, to track the file, because it could still find it even when I put it in a folder explicitly excluded from Spotlight indexing.

And then I realised that all my changes had been moves not copies. If I did anything which involved copying the media and then deleting the original, FCP could no longer track it, whereas, if it were using Spotlight metadata, presumably it could track that in the copy too.

Now, I don’t know much about the deeper workings of HFS+, but I’m guessing that it’s effectively tracking ‘inodes’ here, which means that the same bit of content can be found, whatever name it may have in folders. This, however, will only work with the original copy on the same disk. If you start shifting files around between disks or servers, you’ll thwart it!
