I get an error FILE ERROR: UNKNOWN FILE when I try to import a MP4 file into Final Cut Pro using Calibrated{Q} MP4-EX Import?
This could be one of two reasons:
1. The MP4 file you are trying to import is not a XDCAM EX and/or JVCProHD MP4 file. To see if this might be the case, open up the MP4 File in QuickTime Player 7.6. If QT Player 7.6 cannot open the MP4 file then that means that the MP4 file is not supported.
2. The TypeCode of the MP4 file may not be one that FCP recognizes. If you can open the MP4 file fine in QuickTime Player but not in FCP then this is probably the case.
Try setting the 'Auto-Change TypeCode' to 'MooV' in the Calibrated{Q} MP4-EX Options application.
-Open the CalibratedQMP4EXOptions.app in the /Applications/Calibrated/Applications/Options folder
-Set the 'Auto-Change TypeCode' to 'MooV' and then press 'Apply' and then 'Ok'
-Restart your computer.
-Open the MP4 file in QT Player and then import into FCP
