Dual Core CPU/ HT CPU/ HDV 1080i

    Hi,

    I'm still a little confused.

    I have a 3.2 GHZ HT box which in device manager lists the CPU twice.

    I guess listing it twice doesn't make it a "dual processor"..right? But I
    guess all HT cpus are listed twice?

    I know Intel is coming out with a new Extreme edition P4 processor, dual
    core and Hypertreading, hope that will cut it for 1080i hdv editing.

    Hate to spend a fortune on a dual socket Board if this newer chip will do
    it.

    Your assumption is correct. I noted the two processors in the device manager
    on my first P4HT workstation and all since. It's normal. We don't have two
    chips - we've got one with multiple personaility disorder. ;)

    "Extreme Edition" HyperThreading, as I understand it, changes nothing but
    adding a larger on chip cache - 2MB versus 1MB standard.

    I can't comment on "dual cores" but here's an article:

  3. With HD and HDV editing the faster the processor the better the editing
    experience. Here's a link to the Canopus HDV Education site. Read this and
    you will see what is important to consider when editing HDV and HD video.

  4. We found that the graphic card is the biggest helper.
    In our test a single P4 2.4 ghz (with a x800) was faster then a dual 3.4ghz
    Xeon system, by allot.
    This is only true for next gen video app/engine.

    But GPU accelerated video tools should start to show up at NAB 2005 (next
    week)

    We plan to show a product where we do complex compositing of multiple
    layers,
    color correction on each layer, advanced 4:4:4:4 128bit vector keying (with
    pre/post color correction),
    alpha channel processing, garbage matte, softedge cropping , pan/zoom and
    defocusing , all at once in realtime with HD clips, using 50% of a 2.4ghz
    processor.

    But HDV mpeg2 is not seeking friendly. Transcoding help editing performance
    greatly.
    For our demo we use 1440x1080i uncompress 4:2:0 , ~250gig for 1 hour of
    footage.
    (Still HD are very cheap, that working lossless with minimal CPU overhead is
    worth it)

    I think the future is very bright for HDV,

    The future's bright.

    It's the "now" that isn't so rosey. <tongue firmly in cheek ;>

    p.s. if I had the money, you can bet my tune would change and I'd be right
    on that early-adopter bandwagon.

    I do not know what you meant by seeking friendly.

    I guess my main question is will using a x8oo graphics card with a 3.2 or
    3.4 GHZ processor allow me to edit HDV (1080i) in Premiere pro?
