Sorry if this is actually an easy to fix problem, I wasn't sure what to search for to try and find the answer to this. I'll try and explain the problem as best I can.
I've been attempting to encode a friend's capture of Battlestar Galactica episodes from HDTV. He captured and editted the out the commercials, then deleted the source files, so I no longer have access to those, just the editted version.
The problem lies after I run the .ts files (or the .ts files converted to an mpg, doesn't matter which) through DGIndex (with Honor Pulldown Flags enabled), and then look at the .d2v using an .avs (with no filters) in VirtualDub. The first 5 or so minutes of the episode is fine, but right after the theme, there's a commercial cut, and I'm assuming this causes the problem:
Basically, the fields are out of order. It follows the 3:2 pulldown pattern, except on the 2 frames that were telecined, the fields are really weird. Using SeparateFields, this becomes easy to see. The first three progressive frames have no problem; SeparateFields shows each frame twice just like it should since the fields are separated. The fourth frame and fifth frames, or the telecined frames, have the field order mixed up. The beginning of the episode is BFF, while this part is TFF. This causes incredibly jerky movement during motion, as the fields seem to be in this pattern: 1122335454 (I think). Now, this should be easy to fix right? I just specifiy AssumeTFF for that part of the encode?
Well, it doesn't work when I do that. When I do use AssumeTFF, the pattern changes into something all messed up that I can't seem to figure out, which still has extremely jerky motion, but not nearly as jerky as before. However, it is incredibly noticable and annoying. As far as I can tell, the AssumeTFF has correctly fixed the problem with one of the telecined frames, but the other remains messed up. I really can't explain it. Unfortunately, the clip I have of this is in the neighborhood of 48mb, and I have nowhere I could upload that to for anyone to look at. The most I could do is provide a series of screenshots in order of how it looks, which I will do if requested.
If anyone can help me figure this out, I'll thank you forever.
