Sound cracks & pops using studio 9se

Hi, I am using pinnacle studio 9se to create dvd's from my jvc vhsc
camcorder. The picture captures fine, but for some reason when the captured
video is played back (before and after rendering) the sound is full of pops
and cracks continously throughout the video. I get the same problem if I
capture from my sony video recorder. The sound is captured using the line in
on my creative sb live 1024 player, but during capturing, the sound quality
is perfect, the problem appears to occur between capturing and saving the
resulting avi to the hard drive, because playing back the saved avi file
within windows media player results in the same popping noise on the video.
Any ideas would be very much appreciated.
Thank you

 

Hi Phil,

There a many possible reasons for audio and/or video to get messed up
when capturing analog video, especially VHS-C. From your description
the most likely problem is that you are trying to digitize a very
unstable video signal and fields (or even frames) are having to be
dropped, repeated or replaced to keep the video flow going.
Unfortunately, while you usually can not see this taking place unless
it is really bad, you can definitely hear the garbage being introduced
into your audio stream to keep it and the video together.

Remember, VHS is a terrible format, and VHS-C is even worse. If your
camcorder is old and the tapes are old, there could also be all kinds
of wear and stretching that has made your tapes nearly unplayable.
While you might be able to watch them on a TV, capturing all that junk
to a usable file on your PC is not an easy or effortless task.

The quickest and easiest way to check if you have time-base problems
is to run your analog video signal through a time base corrector
before it is captured, and see if the audio problems disappear or get
better. See if you can borrow or rent a good quality SVHS deck with
built in TBC and try to re-capture. There is about a 90 percent
chance this will fix your problems.

Hope this helps,

Susan

 

Hi, thanks for your input. The camcorder is a new model, only about a year
old, and the tapes are also brand new, never been used before. This is a
problem that I never had whilst using studio 7 on windows98 (although i did
have plenty of other problems using studio 7 on win98), so i would appear to
be something that has been introduced with either the later version of
studio, or maybe even something to do with the soundcard on winXP.
The video capture is perfect, and I can capture 2 hours worth of video
(broken down into 10 minute sections) without any dropped frames at all.
