Distorted sounds on different camcorders - miniDV

Discussion in 'Video Cameras' started by matthew.larkin, Jun 27, 2006.

  1. I posted the text below to rec.video earlier today, but this seems a
    more sensible group as I'm in the UK! Any help gratefully received!



    A relative of mine has had a JVC digital camcorder for a couple of
    years now. A couple of weeks ago the CCD packed up, so she has picked
    up another one (a samsumg I believe).

    She started to play back tapes recorded on the JVC (which play
    perfectly via the JVC) via the samsung, and the sound is coming out
    highly distorted. Recordings made and played back on the samsung come
    out perfectly.

    She's taken it back to the shop she bought it from, and they have
    played the old (JVC recorded) tapes on a variety of different
    camcorders, and some exhibit the same issue, while others don't.

    I'm getting hold of the new camcorder at the weekend to have a fiddle;
    is there anything that you can think of that might cause this? 12bit
    vs 16bit shouldn't be the issue, nor should mono vs stereo recording
    (though correct me if I'm wrong).

    I'll copy the tapes over to my HDD via firewire at the weekend and see
    what the detail of the files shows (particularly if there is any
    difference between old recordings and new recordings), but some
    pointers in the meanwhile would be really helpful.

    Thanks in advance for any help!

    Could it be that one of them records PCM audio, while the other records DV

    I've no idea if they are one and the same thing, but the literature for my
    XM1 made a big deal about the fact that is records PCM audio (through its
    shite microphone, it has to be said).

    In message <>,
    Were the recordings made in LP mode? This has been known to result in
    problems when replayed on another camcorder.

    Thanks for the pointers gents. LP had occurred to me too - its my mum,
    and knowing how tight she can be I suspect she did use LP on the
    original camcorder.

    Solution is likely to be to play them back to my PC and record them out
    to my miniDV camcorder to give her copies that are like new.

    When I've got old and new recordings on my PC I'll also compare the
    contents of the audio tracks using virtualdub or similar just to see if
    there is any technical difference.

    Thanks again for the input!

    I got both of the camcorders together this weekend, and to cut a long
    story short it seems that the problem must have been misaligned heads
    on the JVC unit. Changing short play / long play made no difference.

    However, I can successfully capture the JVC tapes via firewire onto my
    home PC and then play them back out onto my Panasonic cam to re-record
    them effectively with no data loss. The Panasonic tape then plays
    perfectly on the Samsung!
