Jumpy Sound capture off DV (VS8)

[sismithin0]

Hi
When I capture any DV footage off my camcorder the first 2 seconds of sound is fine but then it jump's and continues all through. When I save a Finnished movie to AVI the sound is still jumpy, all untill there is no DV footage with the sound track. I.E at the end!
This has been driving me nut's can any one please help me.
My camcorder in a Sony Digital 8
XP, 256 RAM. 200GB storage. any other info let me know.
thank you very much

Try changing the DV Type -- there is a Type 1 and Type 2, the difference is how the audio is included in the file. One interleaves the audio, the other includes it as a separate stream.

Also check what audio sampling rate was recorded, and what you are capturing?

I remember my Sony Digital 8 (TRV120) had a recording default from the factory of 32khz audio -- I changed it to 48khz audio, and have left it that way ever since...

I have tyed caputring it on DV 1 and DV 2 but i still get the same old problem. The sound is fine for 2 seconds but then just jump's like it gets stuck almost. The Picture quality is perfect but the sound is not??
Also i have tryed capturing it VCD format and the sound is ok then, but the picture quality is not as good, and it takes alot of time to render the frames, what ever that means???
Any suggestions.
Thanks

Try bringing up Task Manager while capturing to see how much memory is available. 256MB really isn't enough, especially with Windows XP. It is possible that your system is constantly swapping to and from virtual memory, and with the high I/O demands of DV capture, unable to keep up with the incoming data.

I have just tryed capturing DV camcorder footage in
VS 6 and that capture the footage sound perfectly, but on the other hand the quality is not exelent. I now know that it's no my camcoreder that's wrong it's somtihng to do with VS 8. I know 256 RAM is not much, I am gettin 256 more soon though so that should be a lot beeter.
Does any one still know how i can capture better sound on VS 8??? I'm baffled I really am???

Have you tried capturing to Dvd Pal Mpeg 2 template.

I have tryed capturing loads of ways.
I brought up task maager and CPU was 100% so I think that is the problem. Memory was up to like 300!!!!
I am getting some more RAM soon will this resolve my problem?
Thanks for all your help

I'd see who the offender is as far as CPU usage is concerned, but I strongly suspect that adding memory will fix your problem. If UVS is not the process that is taking all the CPU cycles (it probably isn't, since DV capture doesn't require much CPU time), it probably is the VMM in the OS itself (listed as System in Task Manager).

If you have a virus scanner, I would also configure it to exclude your capture directory if the program allows this.
