    Hi guys. I recently purchased a Sony TVR-33 and I am really happy with it. :cool:
    Question is, as a newbie to these things what is the advantage of getting firewire over the standard supplied USB cable?

    Cheers.

    The supplied USB cable can only be used to download stills from memory card or tape or for useing the camcorder as a web cam. You cannot use it to download full quality video.
    Firewire gives a lossless copy of your video in its origional format (AVI) and the camcorder can also be controled by the PC during capture. It is the only way to get the video at full quality onto your PC.

    Don't forget that you'll also need a firewire card in your PC if you haven't already got one.

    I think that the main difference between Firewire and USB is that Firewire has a constant transfer rate, whereas USB fluctuates. This is why Firewire is better when transfering data such a video.

    This may seem a daft question, but how will I know if I have a Firewire card in my PC before going out and buying one? I've just got a Sony TRV14 and I am a complete novice. :rolleyes:

    Hi Anchovy,

    You need to see if you can find a firewire socket (some motherboards have them built in these days, some are seperate cards)...

    The sockets come in two types... there is a picture of both sockets and both cable types on this page:

    http://www.cofa.unsw.edu.au/units/resource/equipment_guide/av_connectors/connectors.shtml

    (The sockets are towards the bottom of the page labelled firewire)

    Also watch out for the larger 6pin sockets... I think they look a little similar to USB sockets to the casual observer... (but they have angled corners at one end... USB doesnt)

    The sockets have a few different labels so look for those as well:

    iLink (usually on sony kit I believe)...
    IEEE1394 (usally shortened to 1394)...
    DV...
    or Firewire! (rarely labelled this)...

    Hope that helps...

    Mark.

    Well not really I tink.

    USB 1.1 ~ 12mbps max

    FireWire = 400mpbs

    It just has more bandwidth so it can shift more data.

    FW is faster and is the numero uno in DV world.

    USB2 is faster than Firewire.
    USB2 is used on all the new DVDCAMs
    From Sony Hitachi and Panasonic and are
    backward compatable with the slower USB 1.1

    DVDCAM:smashin:

    Ah

    I did say USB1.1 btw and not USB2.
    I was refering to DV as in miniDV. Probably should have made this more clear. I don't think their is a miniDV cam that uses USB2.

    USB2 may have a bandwidth of 480mbps BUT it is STILL slower then FW for HD and other external transfers from the pc. I'm also assuming it is the same for the DVDCAMS. May have more bandwidth but it is still slower then a FW device.
