    or
    1 mov with 1024 x 768 PhotoJpeg Uncompressed

    2 mov with 1024 x 768 PhotoJpeg 75%

    4 DV movs from the original Cat Library.

    gian - please can you do a little test-

    remove raid - just work with 1 drive - and give us the result of your movie tests

    Hello

    Just thought i would fill you in on my findings.

    I have tried a setup using a Mac Pro, Dual Quad 3.0Ghz, 4GB RAM, with an ATI Radeon X1900XT, outputting the video at 1024x768 on DVI to a second display.

    I have then setup two video drives,

    1 - 150GB 15000rpm SCSI Drive
    2 - 2x150GB 10000rpm SATA Drive, In Raid 1 (Mirrored)

    I am using the latest release of Catalyst, and all the current updates from Apple.

    All test conducted with DV footage, motion JPEG to follow

    Results:
    SCSI
    DV at 720x576 - 5 Layers till frames dropped
    DV at 1024x768 - 4 Layers till frames dropped

    SATA
    DV at 720x576 - 5 Layers till frames dropped
    DV at 1024x768 - 4 Layers till frames dropped

    This is with no processing and playing full screen, not that it matters as teh CPU never went above 20%.

    Cheers

    gareth-

    dv doesnt work at 1024x768 - you can create the movies but it doesnt work- all quicktime does is resize a 720x576 movie. DV is both fixed size and fixed bit rate.

    did you install the latest version of the atto scsi drivers - the ones on any cd didnt work last time i tried?

    http://www.attotech.com/software/drivers.html

    its shown as version 4.1 on the UL5D driver page.
    you will need to login and create an account - if you havent.

    if you didnt you need to as the default driver has very poor performance.

    Hi Richard

    Yes i do have the latest drivers from atto installed, and just to add some more detail, the SCSi drive is a Fujitsu MAX3073NP, and the SATA drives are the Western Digital Raptors WD1500ADFD.

    I can't believe i never new that about DV, doh, i am just about to encode the same video footage as Motion JPEG at 60% and see how they compare.

    Cheers

    there are many different dv settings too.

    you need to check which dv codec you used.

    you need to email me your pdf profile so i can check your files.
