I can’t answer your question—your information/query is too general– it would be helpful if you include some additional information:
1- Your clip lengths (total amount of footage) that you are trying to import. Include bitrate (25/35,etc)
2- Your machine (4 proc/8 proc MacPro/G5, etc.) and processor speed/RAM, etc.
3- Your storage. (Single drive or SCSI/SATA raid)
4- OS/QT/M100 version.
5- A description of HOW LONG it is taking to import convert. (ie. a 4 minute clip loaded directly from the camera is taking 40 minutes to convert, etc.)
