Having tried all know resolves we weren’t able to reduce the problem on the current Mac 10.5 / XSAN / FCP platform. Curiously the problem appears unique to only pro-res.mov files ingested to FCP from Panasonic AVCHD source, all other files behave perfectly. The problem continued outside of FCP while copy those same files across networked directories suggesting it’s most likely a file manager or metadata server related problem. We’ve temporarily worked around by pulling footage direct from RAID to FCP via eSATA. It’s extremely slow but does not show these problems. We are rebuilding the server farm to XSAN 2 and will try again.

It’s worrying that this problem just started with AVCHD -> Pro-res 4:2:2 files ingested from new Pana AG AF 100. Thanks Peter for sharing your experience, If anyone is aware of this problem we’d love to know. This problem is costing us considerably.

Thanks for your thoughts Steve, much appreciated.

Files are backed up on dual redundancy offsite RAID over permanently mounted fibre linked SAN, so they should be pretty safe and yes we always L&T from the source. (I assume the file structure off source is the same??) We have always and still are direct ingesting P2 and other data formats as pro-res 422 without an issue, but with this new PanAF AFCHD- dramas!!

So that takes us back to the problem.

Curiously while the offline issue is always there at FCP start-up, where in the file directory it manifests itself changes. After launching FCP and importing files the file directory is duplicating some files (not all) and creating new file names. It appears at face value that FCP, or the file management system on behalf of FCP is tampering with the file / naming structure??.

While we can only ingest AVCHD on v.10.6 the transposed PR422 files should have no compatibility issue with v10.5? In any case we’ve tried on both 10.5 and 10.6 (we run both for various reasons) in case there is a difference in embedded header info, but no resolution. Starting to think this may be an Xsan issue.

Is anyone else familiar with this problem?

Gareth, did you happen to find a resolution to the problem of AVCHD files going offline in FCP? Or are you still using your Clipwrap work around? I’m having the same problem.
