Hissinng/Static on audio track

[mjkc]

Hi

When I capture a video in MPEG format I get a lot of static in the background.

I have tried de-multiplexing the Audio/Video, then editing the Audio to remove the hissing, but when I re-multiplex the two together the hissing re-appears.

Anyone have any ideas?

Thanks

Yep, I think I know what you mean. I had (have) the same thing but I've found a solution. I always convert with Flask and in that program you can mess with the audio so I increased the volume of the sound. Now I can't hear it anymore (yes, sometimes, but exceptionnel).

AND what's better: while playing the VCD on my standalone, th noise is gone, so it's not such a big problem.

Thanks very much for the help :)

I discovered last knight that the problem was more basic than that though (it might help you as well). It was the built in sound chip on my motherboard!

I have now disabled this and am using a sound blaster live card which works fine.

Why the hiss should re-appear when re-multiplexing I do not know. Perhaps this process used the audio chip to re-multiplex.

How do you disable that? Than I can do this also. I know, it's very strange it only happens when it's multiplexed... (A job for Mulder and Scully :) :) :) )

I turned mine off by going into BIOS and there was an option "Disable on board sound".

Hope this works for you :)

Thanx, I'll try it (when I reboot my pc over 6 months or something :-)
