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).

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??
