Hi All,
This may have provided a problem for some or many of you, so I thought I'd report in on it.
The Problem
~~~~~~~~~~~
When editing hand-held footage I frequently use event Pan/Crop and/or Track Motion to adjust the verticality of background objects. I have found that 'horizontal' lines can be all over the place but, if obviously vertical objects (buildings etc) are off then it offends the eye. I have never had any problems with this until recently. The raw avi clips looked fine but, when rendered after applying Pan/Crop and/or Track Motion, all the vertical lines were WAVY!! And I mean REALLY wavy!! Obviously some parameter had changed but I couldn't see what. If I recall correctly, this was most predominant when the camera followed a person walking (it was a couple of modelling exhibitions) but less so when the camera was stationary.
The Solution
~~~~~~~~~~~~
After a few days of looking, leaving, wondering, and returning. I finally ticked the Properties/Reduce Interlace Flicker button and that fixed the problem. Recall that this is for a normal avi file, not for a still. However, this should not have been necessary so I was not yet content.
The Cause
~~~~~~~~~
OK, if you've read this far, have you guessed what the cause was, yet? Some days later, after I'd already sent out a couple of dud DVDs (just relatives, not customers, at least) I thought I'd check the parameters of my camera. The analog-to-digital conversion feature had been left switched ON. In my camera it's called AV IN/OUT SETUP, DV OUT, ON/OFF. I had recently recorded some VCR tape to Vegas directly via the camera and forgotten to switch it off afterwards. The manual warns that "the quality of the image may be disturbed". Well, to some extent, it wasn't. It looked OK until after it was rendered, and, even then, untouched clips still looked OK.
Well, hopefully this information may be of some help to someone, someday.
Regards,
Neil Porter
