Hi,
I've been spending about 2 hours trying to manually determine an IVTC pattern with my DVD in TMPG as outlined in Doom9's Nandub encoding guide. However I am still completely stumped. My video source is:
4:3 aspect
29.970 NTSC
interlaced
The guide says I need to do IVTC with NTSC, so I do. I pick field order A, as this looks fine and B looks horrible. Now I try to pick my pattern in inverse telecine. Here is my HUGE problem. I jump ahead and look through my frames and find 1 frame that looks perfect and is not all horizontally jagged and interlaced-lookin. I look for my next, and next, and end up with a pattern like this:
1 0 0 0 0 0 1 0 0 0 0 0 1 0 0 0 0 0 1
Then I skip to another part of the movie which actually turns out worse.
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
Every frame has a high flicker rate and every frame looks horribly interlaced. (sigh)
So right now I'm stuck. I'm positive my field order is correct. I'm positive I've followed the guide exactly. It was all very easy up to this point.
Can anyone please help me with this problem? I believe the original video source was not shot on film, maybe digital for videotape. It doesn't look like film, more like the pictures from a highquality digital videocamera. This might or might not be important, just thought I'd better put include that info.
Many eternal thanks in advance, Dave
