    Hello everyone -

    I was under the impression that digital camcorders hitting the market
    nowadays are able to interface with a desktop PC via USB 2.0. I paid a visit
    to best buy, where it was explained to me that the USB 2.0 connection is
    strictly for uploading still images taken with the camcorder. The video
    interfaces via Firewire only. He proceeded to explain the nature of the USB
    connection vs firewire, and he concluded by telling me that because of how USB
    2.0 works, video will never transfer thru it. I ask because I have USB 2.0
    but not firewire. Seeking clarification on this matter. thanks alot!

    For this moment this is indeed the situation.
    A firewire card is not very expensive. So that shouldn't be a problem.

    With some camcorders you can capture low res video.

    Via USB.

    Yes, you're right. But who wants such a low res video?

    The latest Hitachi DVD-RAM cam appears as a removable mass storage device,
    with a drive letter. Drag and drop copying of files - up to 7x real time.
    While there's no protocol for device management, this kind of "capture"
    certainly has some aspects to commend it. Taken together with a DDR400
    FSB400 HT PC to edit the MPEG-2 GOPs, and software to suit - there's a case
    that this path offers the highest prospect for productivity yet.

    Shame the resolution is upper - 400s - maybe Hitachi will get serious and
    do a 3CCD DVD-RAMcorder? Or are they waiting for MPEG-4 and/or
    Blu-ray/Blue-laser.

    : DVD would allow a computer DVDROM drive to play the disks, no need

    : supported in that, including deck control (important for batch
    : captures).
    :
    : DVD would be like USB disk drive equivalents, from a software
    : interface standpoint. I could see running them via firewire. But
    : firewire is effectively a network drive protocol while USB is a
    : peripheral device (host controlled) protocol. So either can work, but
    : firewire isn't likely to be supplanted by USB for DV tape or
    : comparable future technology.

  7. Writing directly to MPEG2 is a fairly serious compromise for high
    end production. DVD writing at DV data rates, to make good use of the
    extra cost of a good 3CCD camera, would get very short recording
    times.

    Like Sony's MicroMV, the technology seems aimed at consumer home
    movie making. MPEG2 with limited edits is fine for that. Likewise,
    if the target recording medium is DVD, that is quite nice too. Also,
    some DVD players can play DVD-RAM, though I haven't checked whether
    they support this camcorder format -- but it seems like a logical
    option. No editing to play on TV is even easier than fast USB
    transfer.

    DVD-RAM/R camcorders - the latest Hitachi uses USB2.0 to transfer data from
    Just to add some more details about other camcorders. I personally own
    a Panasonic VDR-M30 with DVD-R and DVD-RAM MPEG2 realtime recording
    capabilities with USB, but I am sorry to say that it is USB1.1 and
    _NOT_ USB 2.0 as somebody said.

    And yes, you can use the DVD-RAM as an external rewritable hard drive
    - once you install panasonic drivers, but it's still at USB1 speed :(

    But here comes the problem: I left my driver CDs at home, thinking
    that I could download the drivers from Panasonic's site, but surprise
    surprise... THERE ARE NO DRIVERS ON THE WEBSITE!

    I also tried to write an email to them, but 3 days have passed and
    nothing happened. I was pretty disappointed. I do not want to carry
    around all the drivers CD of my gadgets... And, furthermore, knowing
    that the product was still very new, I was expecting a new driver
    release as soon as possible but... Well, if somebody has or knows
    where to get those drivers, please drop me a line or answer here :)

    Thanks
