Late in thanking you for you comments, but… thanks. After thinking about it I realized that a) hard drives are cheap and b) digital assistants are fairly cheap and c) footage can sometimes be priceless. So I opted to archive BPAV files. Since then I’ve realized another really really really important reason to do this: the process of ingesting this stuff is not infallible. We’ve discovered several instances in which importing files to FCP through log and transfer MISSED SOME FILES. Even with double checking to make sure that all the files were checked. So if we had not archived the raw files, we would have been hosed. This has happened to 3 of about 1500 clips.
Not sure what the problem is with import is… some EX3 files actually needed to be transferred from archive drive to a newly reformatted card, then re-import. We are using e-Film cards and readers. I know sometimes, if the camera is turned off and on, it switches cards of its own accord, so I suspect the problem might me that some clips that extend over 2 cards get “orphaned” if they are not imported at the same time. In any case, we now check to make sure that we have sequential file names after importing, then retrieve the archive and reimport anything that was missed.
So thanks for saving my ass on this one.
