General question about Knot

[samfchen]

Hello,

I have 2 fairly general questions, one is about Gordian Knot (couldn't get Xmpeg working no matter what..something about error writing to a file), and the other is about DVD conversion in general.

1) After Gordian Knot, I have 2 files, (assuming the .avs file is foo.avs), foo.avi && foo-movie.avi. The previous one being bigger then the second one. Which one is the correct final output file?

2) The source is NTSC, 29.970, at a 95%+ rate. Thus under dvd2avi, ForceFilm was implemented. But after the entire gordian knot process, I find the film looking a little "ghosty" with some horizontal lines at the moving edges, especially when lots of motion is involved. Is there any filter that can be applied or should be applied prior to applying divx? Deinterlace?

Thanx in advance,
Sam:)

1) foo.avi. foo-movie.avi is the movie without the audio track

2) what movie? maybe you can post a screenshot. You probably need IVTC (deinterlace should be your last shot only) but first let's make sure that it's really interlacing artifacts.

Was a screenshot ever made available? I'd like to learn by looking how to identify "interlacing artifacts."

There are examples available. I searched www.google.com with "interlace" and "artifacts" and found this commercial page with an example in it from the movie, "Top Gun":

If I am correct, DVD2AVI giving you NTSC 95% or higher _usually_ (not always tho) means this movie was shot on video and the original framerate was 29.976 fps. IVTC (/ForceFilm) will not help a bit then, it'll only make your movie jerky.

I'd say don't use ForceFilm, use DeComb's deinterlacing functionality instead. Alternately, to make sure you can check how many frames are interlaced: if 3 out of 5 frames are interlaced, then apply a IVTC filter, otherwise stick to DeComb's deinterlacing.
