    They brought out the camera and, on May 1, they're bringing out the
    editing solution :)

    Sony Creative Software Launches Free Update for Vegas 7 Professional NLE
    — Complete with Support for Sony's New AVCHD High-Definition Camcorders
    Vegas Software and AVCHD Camcorders Deliver Efficient End-to-End
    Workflow Solution for Producing Quality High-Definition Content on the
    Desktop

    (MADISON, Wisc., - April 25, 2007) Sony Creative Software, a leading
    provider of professional video and audio editing applications, today
    announced the May 1, 2007 availability of a Vegas® software update,
    version 7.0e.

    Free for all registered Vegas 7 users, this significant update further
    promotes Sony Creative Software’s support for HD tapeless workflows by
    allowing users to edit files recorded on Sony’s AVCHD™ high-definition
    camcorders, including three new models announced separately today: the
    HDR-SR5, HDR-CX7 and HDR-SR7. These cameras continue to position Sony as
    the leader in high-definition (HD) camcorders by offering consumers the
    ability to record in full 1080 HD video and Dolby Digital 5.1 surround
    sound on tapeless formats such as flash media cards and hard disk drives.

    “With the surge in popularity for generating and editing high-definition
    content, Sony Creative Software continues to provide enhancements to our
    applications to meet the needs of our customer base by providing new
    technology solutions for editing HD faster and more efficiently than
    ever before,” said Dave Chaimson, vice president of marketing, Sony
    Creative Software. “The new Vegas 7.0e update arms users with the
    specific creation and production tools for Sony’s AVCHD cameras and
    provides new levels of support for those working with these optical and
    file-based models.”

    Vegas 7.0e allows users of Sony AVCHD video cameras to create
    high-definition or standard-definition content using files recorded to
    their AVCHD camera’s hard disk, flash memory, or DVD. Skipping the
    real-time capturing stage common for tape-based projects eliminates a
    time-consuming step prior to editing. In addition to the models listed
    above, the Vegas 7.0e update also currently supports Sony’s other AVCHD
    camera models such as HDR-UX1, HDR-UX5, HDR-UX7 and HDR-SR1.

    “Nonlinear editing software like Sony Creative Software’s Vegas has
    helped transform the process of crafting a moving story,” said Linda
    Vuolo, director of camcorders at Sony Electronics. “Now, with Sony
    extending this same ease of use and flexibility to both its latest
    update of Vegas and three new AVCHD camcorders, customers have access to
    a suite of Sony products aligned to deliver quality content from video
    capture to editing in HD that is unlike any other.”

    In July of 2007, Sony will also issue an update to its consumer editing
    software, Vegas Movie Studio Platinum Edition 8, with support for the
    AVCHD format, which will allow users to edit files in the new AVCHD
    camcorder recording format based on the MPEG-4 AVC/H.264 codec for video
    compression and Dolby® Digital

    Sony's AVCHD machines arbitrarily limit data bandwidth to between 12 and 17
    mbps (as contrasted with HDV, which is 25 mpbs -- the same as standard DV).
    This results in significant motion artifacts.

    What we need is a truly good consumer HD machine.

    Sorry for the serial posting, but I just looked at the links. Good grief --
    3 hours of HD on an 8 gb card? Standard definition DV-25, i.e. miniDV,
    requires over 41 gigabytes for 3 hours of video. It may be HD in that the
    output is 1080 (the article doesn't say whether i or p), but it's going to
    look awful if it consumes 1/5 the bandwidth of standard definition video.

  5. In LP mode it puts 3 hours on 8Gbyte.
    64000 mbit / (60*60*3) < 6mbps. So pure crap.

    Not really.. what everyone is failing to realize is that were talking
    about a superior mpeg-4 variant compression.

    DV is well.. DV, and HDV is a variant of a very old Mpeg-2.

    So, if everyone is trying to do "the math" in order to make a judgment,
    don't bother until you see for yourself.

    I on the other hand own a AVCHD camera and the quality ROCKS!! AVCHD
    produces stunning HD on my HD TV.

    Bill,
    For whatever it's worth, the technical comparisons I have seen of AVC versus
    MPEG2 show about a 1.6X to 2.0X compression advantage for the AVC encoders
    when compared to mpeg2. The ratio depends on scene content, frame rate,
    resolution, etc., but this is about the type of improvement currently being
    achieved at 1920 by 1080. Thus, to be capturing and recording truly
    equivalent data rates when the AVC approach is factored in, you would still
    need to store about 6 to 8 gigabytes per hour using AVCHD to achieve
    comparable quality to HDV. The AVCHD cameras only capture and store about 4
    GB/hr at their highest quality setting, which is half to two thirds of HDV
    even when making the correction for AVC's compression advantage.

    I have no doubt that AVCHD looks very superior to standard def video, but
    the reviews of AVCHD on the web, in magazines, and in my own personal
    limited comparisons reveal visible and significant shortcomings when
    directly compared to HDV, and with good reason. They are capturing less
    information and detail. Compounding this to some extent is that the AVCHD
    codecs are comparatively new and immature versus the HDV codecs which have
    been improved for years now. As time goes on the differences in performance
    may narrow, but for the time being the two technologies are by no means
    equivalent.

    Mpeg4 is not 500% more efficient than mpeg2. Moreover, Sony has arbitrarily
    limited the bandwidth on their AVCHD machines below the AVCHD spec maximum
    for one specific reason: so that they do not compete with Sony's prosumer
    offerings. Sony has made a marketing decision that consumers will be
    satisfied with lower video quality, and have designed their machines to that
    standard.
    See above. The "stunning" quality that you receive is still below that of
    HDV.

    Well it had to happen some day, PT hit on the real issue/
    problem with Sony's AVCHD. The problem is not with
    the AVC/H.264 format itself but the purely artificial limitations
    Sony put on their implementation of it for their cameras. That
    PT is pointing this out by singing the praises for MPEG2, is
    just gravy from my point of view.

    LoL;

    Ken, as you well know, I've never criticized either the mpeg2 or mpeg4
    codecs PER SE. I have criticized there use and implementation as a
    standard definition capture vehicle. You need to stop thinking of
    temporal compression as a religion and recognize that it is simply a
    tool.

    HDV (mpeg2) is a reasonable compromise (at the moment) for prosumer
    high definition capture, and it is supported by a reasonable range of
    editing options. AVCHD has the potential for higher-quality video,
    but it is arbitrarily and unnecessarily crippled by Sony for no other
    reason than to protect its much-more-highly-priced prosumer line of HD
    cameras, including its HDV offerings. It is also almost completely
    unsupported by reasonable editing packages at this time.

    For the reasons above and the many other restrictive practices that Sony
    have instigated I have, along with many other people boycotted Sony
    products. I have had three high end Sony Video cameras over the last 10
    years but when I move to HD it will not be a Sony regardless of how good it
    may appear. Currently leaning towards Canon!

    Please site the article or prof that Sony is limiting bandwidth of AVCHD.

  13. That is an easy guess. The current recording media can easily handle higher
    bitrates. it is not unknown of camera manufacturers, to protect the
    higher-end market products. Sony for instance has learned what the
    introduction of mini-DV did ;-)

    cheers

    Look up the specs of Sony's camcorders (Sorry, I don't have time to
    google it for you). Sony's AVCHD machines all have bandwidths of
    between 12 and 17 mpbs. The AVCHD spec, like the HDV spec, goes up to
    25 mpbs. Sony's HDV machines all operate at 25 mpbs bandwidths.

  15. And a harddisk does 300-800 Mbit/s easily.
