FCP export of long mxf clips to FAT32
 

THis may be answered somewhere, but a search didn't turn it up. I was trying to export some not-that-long clips (2-3 min) today from FCP to an external FAT32 drive for a Premiere Pro client. He needs them as uncompressed 4:2:2 Quicktimes, which are far larger files than the native mxf. I've done this sort of export before (also to external FAT32) for my animator to composite to, and FCP generated a series of Quicktimes of 2GB apiece, to stay within file size limitations. Everything worked perfectly.

Today, however, on several clips, FCP would start to generate the first file (clip number, followed by -AV1), then would crap out part way through... sometimes after about 1GB, sometimes after only 50 MB. In every case, the error message was "file too large".

Anyone have any ideas about this?

On a related note, FCB wouldn't export any of these longer clips in Batch Export... it wouldn't even try creating the [clip name-AV1] file... it'd just error out of the process.

Since I'm mostly an Avid guy, I don't know if this is typical FCP behavior.
