Proxy Data

Proxy data is made up of low-resolution video data
(H.264) and audio data (AAC-LC). This lightweight
proxy data can be used in the same way as the
original data, but it can be transferred more
quickly, for more efficient viewing and editing.
During clip recording, proxy data is recorded onto
the SD card inserted into the PROXY SD card slot.
PROXY SD card slot
By importing proxy data recorded on the SD
card into a computer, you can quickly check the
recorded content or perform rapid offline editing.
Proxy Recording using the Camcorder
ˎ Proxy recording will not start unless an SxS ˎ
memory card is inserted.
ˎ When the camcorder has been turned on for ˎ
about 45 seconds, the icon (media status
indicator for Proxy SD slot) turns on in the LCD
monitor and viewfinder screen to indicate that
proxy recording is enabled.
If you start shooting while the
flashing or is not lit, proxy files are not recorded.
ˎ Before removing an SD card from the ˎ
camcorder, always check that the ACCESS
indicator for the PROXY SD card slot is not lit,
then turn off the camcorder or turn off the proxy
recording/wireless LAN connection function.
To turn off the proxy recording/wireless LAN
connection function, make the following
settings in the setup menu.

ˎ Attempting to remove the SD card while either ˎ
the proxy recording or wireless LAN connection
function is enabled may display a warning
(E91-1C0) in some cases. If the warning appears
while recording, data is still recorded correctly
to the SxS memory cards, but proxy files are not
recorded. The warning message can be cleared
by turning the camcorder off and then on again.
