2. AVCHD (Advanced Video Coding High Definition) is a file-
based format for the digital recording and playback of high-
definition video.
Developed jointly by Sony and Panasonic, the format was
introduced in 2006 primarily for use in high definition
consumer camcorders. Favorable comparisons of AVCHD
against HDV and XDCAM EX solidified perception of
AVCHD as a format acceptable for professional usage.
Panasonic released the first professional AVCHD camcorder
in autumn of 2008, followed by Sony in the first quarter of
2010.
3. AVCHD 1080i is available on most AVCHD camcorders. For
some models this is the only recording mode offered.
AVCHD-SD is used in the shoulder-mount Panasonic HDC-
MDH1, available on Southern-Asian markets, as well as on its
North American AG-AC7 cousin. Several new models from
JVC like the GZ-HM650, GZ-HM670 and GZ-HM690 can
record AVCHD-SD video too. AVCHD-SD is not compatible
with consumer DVD players, because it employs AVC video
encoding instead of MPEG-2 Part 2. AVCHD-SD can be
played on a Blu-ray Disc player.
4. MTS and M2TS are both file extensions for the high definition
digital video camera recorder format, AVCHD (Advanced
Video Codec High Definition). AVCHD was jointly
established by Sony Corporation and Panasonic Corporation in
2006 for use in their digital tapeless camcorders.
5. Though both MTS and M2TS are file extensions for the same
AVCHD and both support 720p and 1080i HD video formats,
there is a slight difference between the two. In the M2TS file,
the video file is saved in the high definition Blue-ray BDAV
format. Video data on the Blue-ray discs can be saved in one
of the three video codecs – MPEG2 Part 2, H.264/MPEG-4
AVC, or SMPTE VC-1; and the audio data in either Dolby
digital, DTS, or the uncompressed Linear PCM. The M2TS
file extension is written as 'xxxxx.m2ts' where the ‘xxxxx’ are
a five digit number corresponding to the audio-visual clip.

8. For mac user, they want to watch avchd file on mac,then how
to get AVCHD MTS files off HD Video cameras/camcorders
to Mac?
With AVC HD camcorders, you typically need to connect the
HD video camera to your Mac using a USB cable, firewire or
iLink(Sony). Once connected and powered on, the camcorder
should appear on the desktop as a new disk. The location of
the films on the camcorders disk will vary depending on
manufacturer. It is desirable that you copy the movies to your
Mac hard disk before converting or editing.
9. If you want to playback your video to computer, you will find
most AVCHD camcorders are with high definition
M2TS/MTS format. This format itself is good even perfect,
but for Mac users, they must pay some effort to make it works
well with their PC or Book. From QuickTime, iMovie, FCP,
iDVD to YouTube, AVCHD M2TS format is not a fully
compatible format. Even the latest iMovie'11 and FCPX. It can
do nothing when the M2TS can't be detected by them. You
should to convert avchd video on mac, there are many
softwares can help you do this, AVCHD converter mac is
one of the software.
