It is not possible to delete clips on an AVCHD volume, even if read-and-write permissions on the volume are set to allow file deletion. This behavior is different from that of P2 volumes, where clip deletion is allowed when proper read-and-write permissions are set.The Log and Transfer window shows only an average duration for AVCHD clips, especially clips longer than 1 minute. After clips are ingested, the correct duration is displayed in the Final Cut Pro Browser.
