What is the AVCHD format?
The AVCHD format is a high definition
digital video camera format used to record a
high definition (HD) signal, using efficient
data compression coding technology. The
MPEG-4 AVC/H.264 format is adopted to
compress video data, and the Dolby Digital
or Linear PCM system is used to compress
audio data.
The MPEG-4 AVC/H.264 format is capable
of compressing images at higher efficiency
than that of the conventional image
compressing format.
• Because the AVCHD format uses a data
compression system, images may be distorted in
scenes where the image, angle, or brightness
changes drastically. This is not a malfunction.
Recording and playback on your
camcorder
Based on the AVCHD format, your
camcorder records with the high definition
image quality (HD). In addition to high
definition image quality (HD), your
camcorder is capable of recording a
standard definition (SD) signal in the
conventional MPEG-2 format.
Video signal*: MPEG-4 AVC/H.264
1920 ×1080/60i, 1440 × 1080/60i
Audio signal: Dolby Digital 2ch
Recording media: memory card
* Data recorded in AVCHD format other than the
above mentioned cannot be played back on your
camcorder.
• 1080i specification
A high definition specification which utilizes
1,080 effective scanning lines and the interlace
system.
•
A memory card formatted by a computer
(Windows OS/Mac OS) does not have
guaranteed compatibility with your camcorder.
• Data read/write speed may vary depending on
the combination of the memory card and
memory card compliant product you use.
• Damaged or lost image data will not be
compensated for, and may occur in the
following cases:
– If you eject the memory card, turn the power
off on your camcorder, or remove the battery
pack for replacement while your camcorder is
reading or writing image files on the memory
card (while the access lamp is lit or flashing).
– If you use the memory card near magnets or
magnetic fields.
• It is recommended to make a back-up of
important data on the hard disk of a computer.
• Be careful not to apply excessive force when
writing on a memo area on memory card.
• Do not attach a label or the like on memory card
or a memory card adaptor.
• Do not touch, or allow metallic objects to come
into contact with the terminals.
• Do not bend, drop or apply strong force to the
memory card.
• Do not disassemble or modify the memory card.
• Do not let the memory card get wet.
• Be careful to keep memory card out of the reach
of small children. There is danger that a child
might swallow it.
• Do not insert anything other than the compliant
size of memory card into the memory card slot.
Doing so may cause a malfunction.
• Do not use or keep the memory card in the
following locations:
– Places subject to extremely high temperature,
such as a car parked outside in the summer.
– Places under direct sunlight.
– Places with extremely high humidity or
subject to corrosive gases.
x On the memory card adaptor
• When inserting memory card into a memory
card adaptor, make sure the memory card is
inserted facing in the correct direction, then
insert it all the way in. Note that improper use
may cause a malfunction.
