What type of firewire cable

Discussion in 'Video Cameras' started by Nick Le Lievre, Dec 3, 2006.

  1. Would go from a Canon MV900 camcorder into a Lite-On LVW5006 DVD Recorder ?
    Is it 6 pin to 4 pin? and is it the same as the one for the computer?

    Thanks

    Would go from a Canon MV900 camcorder into a Lite-On LVW5006 DVD Recorder
    From the limited amount I've been able to find, it would be 4pin to 4pin,
    based on the recorder's specification showing the front-panel IEEE1394 to be
    a "mini port". The camera will certainly be 4pin. You need to look at your
    camera and your recorder and decide for youself. If the DVD recorder's
    firewire port is the bigger one, then it's 6pin. If it looks just the same
    as the one on the camera, then it's 4pin.

    Just downloaded the manual, and yes - it's 4pin to 4pin.

  5. The picture of the Lite-On appears to show a 4-pin. The camera will
    certainly be a 4-pin.

    I assume you don't yet own the equipment? Else you'd just look :)

  6. I have the Lite-On at home but I`m not there this weekend so I can't look...
    the MV900 is in the post.

  7. Please would someone point me to a FAQ?

    I have both copied DV to VHS and edited video on my PC using Pinnacle
    and now Premiere Elements and saved back to tape and made DVDs. All
    this is fairly straightforward.

    What happens when you connect a DV camcorder to a stand alone DVD
    recorder? What does the DVD recorder do to the data to make a DVD.
    Does it take ages? and what quality is it? Somewhere there must be an
    description of the process, codecs etc.

    Thanks folks

    If anything, the second paragraph is even more straightforward than the
    first. DV transfer* is a strictly real-time process, like the VHS tapes. The
    DVD recorder in question can control the camera when connected via firewire,
    so you can cue the tape to the point you want before you start recording.
    The recorder will have the necessary decoder built-in to convert this DV
    data to a picture. The built-in encoder will convert that picture to MPEG.
    The same will happen with the audio, which will be converted from DV to AC3,
    MPA or PCM.

    The only thing that really changes is the data rate. This has a direct
    relationship with the amount of time you can get on a single disc. Dropping
    the data rate means that it takes less bytes for a given duration, meaning
    you get more duration on the disc. It's possible even to quarter (roughly)
    the size of the picture to 352x288 just so you can get the data rate down
    even further. For 6 hours to fit on a single-layer DVD, the video needs to
    be encoded at the sort of quality you get on a VCD.



    * A firewire transfer, unlike an analogue capture (which is still an
    available option with this camera and recorder) is just a data stream being
    transmitted. It is the recorder that converts this stream to picture,
    whereas if you use the composite or S-video (the outputs you'd use to go
    direct from camera to TV) the camera does the conversion from DV data a
    picture, this is sent down the analogue wire, and the recorder encodes the
    ready-made picture.

    Hmm, isn't DV audio uncompressed PCM data [1] to begin with?

    (Of course, if you use the 4-channel 12-bit 32 kHz option instead of the
    2-channel 16-bit 48 kHz mode, the DVD recorder needs to downmix the four
    channels and umpsample the data to 48 kHz.)
