    Default New Guy (or: one of the many lurkers)

    Hiya

    I've been lurking around for a while, and I must say that every problem I have encountered has been answered in a thread on this board somewhere. I commend some of you on your thourough knowledge of some tricky issues, and your willingness to pass the information along to us.

    Thank you. But this time all my reading of posts has not turned up an answer for my current problem.....

    After exporting my video (to DV AVI) with a 'denoiser' filter I get a random popping noise distributed throught the length of the video. I reran the export without the denoiser and found that the same effect was there but I couldn't hear it through the hiss - the denoiser just made it more apparent. When I use headphones on the camera the noise is not there. All of my audio clips are at 48000Hz-16bit-stereo.

    Maybe someone has heard of this phenomenon and can shed some light on it? I'm beginnig to suspect a hardware/cabling problem

    Thanx in advance

    Have you changed the frequency from the original source (48000Hz). Try lowering the gain of your audio too.

    Thanx for your reply Marc

    I make no frequency changes when I capture the original source.

    When you say 'Try lowering the gain of your audio too' , do you mean

    1) while filming
    or
    2) during the capture phase
    or
    3) post production edit and filter application

    Thanks again

    In post production - previous posters have claimed this eradicates any 'popping' noises. Never experienced the problem myself!
