    ....looks good!


    M2TS is a filename extension used for the Blu-ray Disc Audio-Video
    (BDAV) MPEG-2 Transport Stream (M2TS) container file format. It is
    used for multiplexing audio,
    video and other streams. It is based on the MPEG-2 transport stream
    container. This container format is commonly used for high definition
    video on Blu-ray Disc
    and AVCHD.


    The BDAV container format is a modification of MPEG-2 transport stream
    (ITU-T H.222.0 | ISO/IEC 13818-1) specification for random-access
    media, such as Blu-ray Disc,
    DVD, hard drives or solid-state memory cards. The 188 byte packet size
    is increased by a 4 byte timestamp to 192 bytes. It is also informally
    called M2TS.

    The BDAV container format (.m2ts) is a standard used on Blu-ray Discs.
    Blu-ray Disc titles authored with menu support are in the BDMV
    (Blu-ray Disc Movie) format
    and contain audio, video, and other streams in BDAV container (.m2ts),
    which is based on the MPEG transport stream format. The BDAV container
    is also used in the
    BDAV (Blu-ray Disc Audio/Visual) disc format, the consumer-oriented
    alternative to the BDMV discs. BDAV disc format is used on BD-RE and
    BD-R discs for audio/video

    The BDAV container with filename extension .MTS or .m2ts is also used
    in AVCHD format, which is a high definition digital video camera
    recorder format. AVCHD is a
    simpler form of the Blu-ray Disc standard with just one video encoding
    algorithm and two audio encodings. Compared to Blu-ray Disc format,
    AVCHD can use various
    storage media, such as DVD media, memory cards or hard disk drives.
    The BDAV container contains videos recorded using AVCHD camcorders,
    such as Sony's HDR-SR(xx)
    series models. Panasonic, Canon and other brands of AVCHD camcorders
    also store recorded video in BDAV container format. There are some
    problems with AVCHD
    compatibility between brands.


    The BDAV container format used on Blu-ray Discs can contain one of the
    three mandatory supported video compression formats MPEG-2 Part 2,
    H.264/MPEG-4 AVC or SMPTE
    VC-1 and audio compression formats such as Dolby Digital, DTS or
    uncompressed Linear PCM. Optionally supported audio formats are Dolby
    Digital Plus, DTS-HD High
    Resolution Audio and Dolby TrueHD.

    The BDAV container format used on AVCHD equipment is more restricted
    and can contain only H.264/MPEG-4 AVC video compression and Dolby
    Digital (AC-3) audio
    compression or uncompressed LPCM audio.

    File and folder structure

    See also: Blu-ray Disc#Directory and file structure and AVCHD#Overview

    The names of M2TS files are in the form “zzzzz.m2ts”, where “zzzzz” is
    a 5-digit number corresponding to the audiovisual clip. This number is
    also used in the
    filename of an associated clip information file "zzzzz.clpi". (This
    number can be a date and time stamp of when the video clip was
    recorded.) Each stream has its
    own file.

    Files in AVCHD format use legacy "8.3" file naming convention, while
    Blu-ray Discs use long filenames. That's why the filename extension of
    video files is ".MTS"
    instead of Blu-ray Disc's ".m2ts". Also other files use different
    extensions: .CPI - .clpi, .MPL - .mpls, .BDM - .bdmv.

    The M2TS files on a Blu-ray Disc are placed in the subdirectory
    "STREAM" of "BDMV" (or "BDAV") directory, which is at the root level.
    (e.g. \BDMV\STREAM\00001.m2ts or
    \BDAV\STREAM\00001.m2ts) On some AVCHD equipment, the "BDMV" directory
    is located in the "AVCHD" directory, which is placed at the root level
    (e.g. \AVCHD\BDMV\STREAM\00001.MTS).

    Software support

    Almost all commercially produced Blu-ray Disc titles use copy
    protection method called Advanced Access Content System, which
    encrypts content of the disc
    (including M2TS files). Software that supports M2TS files usually
    works only with decrypted or unencrypted files. Blu-ray Disc software
    players can usually play back
    encrypted content from original disc. Video content created using
    AVCHD equipment is commonly unencrypted.

    Currently, M2TS files can be played using the Picture Motion Browser,
    which is an application video player provided with Sony AVCHD

    Some M2TS files can be played with ALLPlayer, MPlayer, VLC and other
    media players, depending on used compression formats in a M2TS file.
    Some players will need an
    appropriate codec, component or plugin installed.

    Current versions of Nero Vision, FormatFactory, Total video converter,
    MediaCoder, HandBrake and Picture Motion Browser are capable of
    converting M2TS files into
    MPEG-4 files, which can also be viewed using the aforementioned media

    Sony products Media Manager PRO for PSP, Media Manager PRO for
    Walkman, and Mobile Media Manager PRO are all capable of converting
    M2TS format to MP4 files.

    M2TS format from Sony is not necessarily the same as that of Panasonic
    or Canon camcorders. However, programs like Sony Vegas Pro and AVS
    Video Editor can open and
    edit both Sony M2TS files as well as Panasonic M2TS files. (Sony Vegas
    Pro v.9 is also capable of reading and editing M2TS files produced by
    Canon Vixia Camcorders.)
    The only other piece of software known currently to handle both types
    is Pinnacle Studio 12 Ultimate and Cyberlink Power Director v8.

    M2TS files can also be played on Sony PlayStation 3s, Sony Bravia TVs,
    Western Digital WDTVs, Xtreamer media player, Amkette FlashTV HD Media
    Player and Panasonic
    Viera TVs supporting playback of AVCHD.

    Apple's Final Cut Pro can read .MTS files (as stored in Sony HDR
    camcorders) by using the AVCHD plugin in the Log and Transfer window.

    Daminion Media Management Software allows to import and manage .MTS &
    M2TS files.
