problems with virtualdub and editstudio

    I'm using editstudio (an old version, 4.1.5) to make a video including
    clips from a moving vehicle on a fairground. I'm trying to use
    virtualdub/deshaker as a preprocessor to remove the camera shake. Should
    be easy, but no.......

    Firstly, virtualdub complains it can't initialize the output codec. Same
    for all of them, except uncompressed. I haven't a clue where to look for
    problems.

    Secondly, if I use uncompressed output (a huge file :) ), it seems
    that what virtualdub outputs (even with no filters) isn't digested too
    well by editstudio. On some scenes, when an object moves across the
    screen, I get am obvious coarse comb effect - the comb appears to be
    /about/ 26 scan lines in period, ~13 left then ~13 right. This doesn't
    appear unless the video has been processed by virtualdub. (A
    single-line-width comb, presumably due to interlacing effects, is also
    evident sometimes). OTOH such a file plays correctly in mediaplayer,
    with no evidence of such a coarse "comb" effect.

    Amazing how the "quick" jobs mess up so readily :-(

    Any ideas would be /most/ welcome - thanks.

    (working on XP, if it makes a difference).

  2. Hi Mike,

    PureMotion has an excellent forum for Editstudio at
    http://www.puremotion.com/forum/index.php. Try to also pose your question
    there.

    Thanks for that. I used to know about that forum ..... been away from
    the video scene too long :-(

    After some trial and lots of error, it turns out the coarse comb effect
    is related to image scaling by EditStudio - I worked around by
    prescaling with virtualdub ......

    ......which /still/ won't use the codecs that have been on this machine
    since year dot. Although it /will/ use new ones downloaded from
    free-codec. Is there a way of reinstalling XP's standard codecs??
