Code:
Mpeg2Source(...) TFM() TDecimate()
Code:Mpeg2Source(...) Interleave(TFM(field=1,pp=0), TFM(field=0,pp=0))

Yep. I was going along OK with script #1 myself, until I got to the scene in question. I figured there would be a trick to it, so I'm off to the TIVTC documentation. Thanks for the script.

I tested with another video, and realized that some frames were not deinterlace.
-
The only place I saw comb artifacts after TFM().TDecimate() was in the fade-from-black at ~44 seconds into the clip. That fade-in was done on interlaced video so every field is different (although it's still normal 3:2 pulldown from the film frames).
Since each field is slightly brighter than the last TFM() can't find a perfectly matching field -- so it uses the closest match, a slightly brighter or darker field. Adding vInverse() to my earlier script will blend away those comb artifacts:
Code:Mpeg2Source("VideoFile.split.2.d2v", CPU=6, Info=3) Interleave(TFM(field=1,pp=0), TFM(field=0,pp=0)) vInverse()
Or you could full QTGMC():
Code:Mpeg2Source("VideoFile.split.2.d2v", CPU=6, Info=3) QTGMC(preset="fast") # or whichever preset you prefer
On the left is Interleave(TFM(field=1,pp=0), TFM(field=0,pp=0)). On the right is QTGMC() -- you can see dark lines ghosting from the next frame. QTGMC() sometimes leads to other small distortions.Last edited by jagabo; 10th Dec 2013 at 22:59.

I solved the problem by using:
TFM ()
TDecimate ()
Vinverse ()
Now, I want to solve another problem identified in the video:
The outline of the picture is bad, perhaps because of the compression. How do I leave them well defined, as are the video before the encode? -

Use a sharper resizing filter. Or leave the video at its original frame size and specify the SAR in x264.
-
I used:
TFM ()
TDecimate ()
Vinverse ()
crop (4, 0, -2, 0)
Spline36Resize (960.720) # Spline36 (Neutral)
Solves the problems of the lines, however, generated macroblocks in the video.Last edited by charlesn73z; 13th Dec 2013 at 10:13.

By doing resize, I noticed that the colors of the video have been changed, why?
-
Maybe your players switches to rec.709 colors when playing videos over 720x480? Maybe you're playing two videos at the same time, one is using video overlay, the other not? Spline36Resize() would not change the colors.
