Hi, I've been using Gordian Knot for some time now, but on a recent DVD conversion the video has a strange "banding" effect at the top of the frame. I first used XviD (07-FEB-2004), then DivX Pro 5.1.1 codecs - same thing.
It seems to come and go regularly, and wondered if I have some settings messed up causing it; something to do with key frames?. A screen capture is shown below:
i used to hate going to weddings, all the old dears would poke me and say "your next", they stopped saying it after i did it to them at funerals -Chopper Reid-

A man who likes his Quality, and likes his Trek, is a good man.
I, therefore, wish I could help you...
Well I can tell you the undesired artifact maybe an anamorphic shadow or 'ringing' which you probably don't get with a non-anamorphic source. I don't think it is a GKnot problem, but might have to do possibly with RFI/EMR in your system case, or possibly your 32/16 rules for pixel resizing (horiz/vert modulus).
It could also be something you see introduced in playback, not really present in the AVI.
I say 'spread spectrum' and not to worry, it's pretty subtle and probably just electronic noise, tough to ID and cleanup! Coupla beers and it goes away.
