Hi All,

Running FCPX 10.0.5

Trying to export 1hr,40min clip. Getting EXPORT FAILED error with description:

The operation could not be completed because an error occurred when encoding frame 5097 (error -108).

Processor Name: Quad-Core Intel Xeon

Processor Speed: 3 GHz

Number Of Processors: 2

Total Number Of Cores: 8

L2 Cache (per processor): 12 MB

Memory: 4 GB

4 Hard Drives: 320GB, 750GB, 750GB, 1TB saving onto the 1TB with 250GB storage remaining.

Any ideas for resolution??

Will try and split clip in half and export!
