dv capture to avi, sound problems

Archived from groups: microsoft.public.windowsxp.video (More info?)

Hi, when I capture from my panasonic pv-gs120 dv link at video res of 720x480
using avi or mpeg2, the playback on my pc has a high pitched audio sound in
the background that is not on the original tape. This does not happen when I
capture using lower pixel res of 640x480 and below... any ideas? I've updated
DirectX driver and am using 1394 shielded firewire but still problems...
thanks...

    Sounds like the squeal of the HOT of the monitor. Do you have a mic
    connected, if so try with it out or muted. If no mic, disregard this. Later
    on.

    Hi Nick...no mic is connected, its not feedback sound, its a very high pitch
    sound, like maybe the audio codec can't keep up with the xfer speed maybe
    (?)... I'm just guessing, but as I said the high pitch sound only happens
    when xferring from dv camcorder to pc at avi or mpeg2 mode... thanks tho...

    There are two likely sources, the Firewire connection or the audio card. If
    you are confident that your Firewire connection is functioning correctly,
    look at the audio. If you are using the onboard audio, that might be the
    more likely issue. Get the latest chipset drivers for your audio. Is this
    machine slower than 1.6GHz (1.0 if AMD)? That could potentially contribute
    if the audio system is sub-par. A remedy might be adding a PCI audio card
    such as a Creative Labs Audigy, but check the audio drivers first!

    The latest DirectX is 9.0c, which is built into SP2. DXDIAG will list the
    version. I highly recommend 9.0c, which you may have ("updated DirectX") as
    you indicated, because it also includes the latest DX security patches.

    Hi George.. thanks for the suggestions... yes I did upgrade to DirectX 9.0c
    via Windows website.. I have an HP 450n which says its a 3gig.. I'm not so
    sure its an audio onboard problem; I'm thinking maybe its a audio codec
    problem maybe? because if I upload the dv video to pc via avi, than burn it
    directly to dvd and play it on my tv, I get the same high pitch background
    noise as I hear on the pc... also, I tried 2 different firewire cables, and
    still get same high pitch noise when downloading via avi or mpeg2 format,
    which is the highest video resolution for capture, but no high pitch noise
    when downloading via regular mpeg or lower video res...

    Yes, this really sounds like a audio driver issue or a potential codec
    issue. Especially if varies based on format via firewire. The audio is
    usually processed through audio chipset. There are certain conditions like
    this where the audio will also get out of sync with the video while using
    firewire.

    Go to the HP site and go to the support page. You can enter your model
    number and get the downloads list for you computer. Download the latest
    audio driver and see if it corrects your problem.

    That was a great suggestion George, I looked at my audio driver and it needed
    an update; unfortunately, it didn't fix the high pitch sound... I guess dv
    download of 178 meg/sec is too fast for my audio codec to process maybe(?)...
    but then again I wouldn't think so, I just bought this HP computer brand new
    4 months ago, so I was expecting the latest and greatest hardware in it...
    it's a 3 gig processor with 160 gig hardrive and 512 meg ram

    I just looked at my pc's Device Manager... and the audio codec manufacturer
    says its a standard system device... so maybe I need to upgrade my audio
    codec maybe(?)... sorry, I'm not a desktop/pc guy, I'm a network guy at
    work.... so I'm not sure if that may be the problem..

    also on my audio codec properties window on the properties tab, the first
    codec it uses is: IMA ADPCM Audio CODEC

    ...there's about 10 other listed audio codecs under that one, maybe I should
    push one of the other codecs to the top maybe (?)... any other suggestions
    would be welcome... thanks for replying George.

    Then it may be the Firewire or the audio chipset itself. What card do you
    have? Your system is fast enough to even capture an analog stream and
    convert it to DV with software.
