Do not erase a folder or file on the memory card with a computer. It may make it impossible to load on the unit. If data is recorded to the memory card with a computer, an error may occur such as an inability to recognize or record to the memory card with the unit. The memory card to use with the unit should always be formatted on the unit. |
Volume label of the memory card
When the file format is MOV or MP4
The value set in the [RECORDING] menu [CLIP NAME] is stored in the volume label in the CAM INDEX+NEXT CARD COUNT format when the memory card is formatted. Once it is stored, [NEXT CARD COUNT] will increase by one. The CARD COUNT that is stored is also used for the CARD number of the MOV format/MP4 format file name.
When recording to the memory card that CAM INDEX+CARD COUNT is not stored in the volume label, the value set in the [RECORDING] menu [CLIP NAME] is automatically stored in the volume label, and [NEXT CARD COUNT] will increase by one. |
When the file format is AVCHD
“CAM_SD” is stored in the volume label.
