    Hi,

    My set up is basically;

    Canopus Storm, Premiere 6, Sony TRV-25 (windows 2000 sp3, dual 2.2ghz
    1gb ram 2 73gb ide drives, one 18gb scsi) - all my video work is done
    on one of the 73gb drives. Capturing by firewire.

    I've noticed that when I capture (either via the Storm software or
    Premiere), that when I play back the raw captured avi file that after
    some time during playback the captured sound is out of sync with the
    video (by about 5 secs).

    If it's just a short capture, it's unnoticable, but it may even be
    happening on these as well I just haven't noticed.

    But say I've captured 20minutes worth, when I play back the avi file,
    the sound in that captured file is around 5secs out (say after
    10minutes of playback).

    Also, I haven't tried to see that this 5 secs would increase with the
    length of capture, but my suspicions are that it would.

    Any idea what this can be due to and how to fix it ??

    Thanks for any advice you can give.

    Is the TRV-25 a digital or analog camcorder?

    Anyway, if you're capturing from analog source (VHS, etc.) odds are that
    you're going to have to stretch the audio to match the video during
    post-processing.

    And 5 sec after only 20 minutes is pretty bad (my Hauppauge card and my
    Turtle Beach Santa Cruz card manage 0.5s after 2 hours on a good tape).

  3. Apparently, this is a common problem.. I had it happen for a while too..
    The way I fixed it was to go get me a new Mac!! :)

    Seriously.. It's caused by audio drifting, and unless you have some way
    to "lock" the audio via either ADVC-100 hardware or some software that
    supports audio locking like.. Scenalizer.

    I higly recommend this capture software.. worth the price!
