OK we’ve just had exactly the same problem: We were working on a project with about 80% of it’s media offline. I brought in some of the media and went to reconnect them to the clips in the browser (as I have done without a problem several times recently) and the reconnect box instead of listing the offline files displayed just one line of text saying [” is missing] (square brackets not included), and FCP is unable to successfully identify the files by searching. I checked the item properties for a sample of these clips and found that the source field for them was also displaying [” is missing].
Somehow FCP seems to have forgotten the names of all the offline files, although the clip names are still intact. the online files seem to be OK. I wondered if this could hapen by telling it to FORGET FILES when loading up a project? But still, i should be able to reconnect them later on I assume and right now it won’t let me unless i do them one by one manually matching the filenames.
Luckily I had a backup on another machine, but this is worrying because it seems like illogical and unpredictble behaviour. Has anyone else got any idea what’s causing it.
