Decimation strategies for strange ABC-HD patterns

[rebkell]

I captured 'Men In Trees' tonight, and I could tell by just watching the show live that it had some of those strange cadences in it: I checked it in at least three segments(segments being breaks after commercials) and probably over a thousand frames and determined that it was dropping one frame out of every 144 frames, it was consistent, the only variation I found was sometimes the cadence would be 3:1 and in other places it would be 2:2 instead of the normal 3:2 repeating pattern.

So what should have been 145 frames was only 144 frames, but it seemed to repeat consistently. The only difference was where I made cuts for the commercials, the pattern might not be offset exactly 144 frames. But in any segment it appeared to have the same repeating pattern every 144 frames.

Any suggestions on decimating this thing?

I'm going to run it with
TDecimate(Cycle=144,CycleR=86) and see how it goes.

I tried that above, but it didn't work that well, the thresholds weren't consistent enough and it kept a few it shouldn't have and deleted a few it shouldn't have.

I'm not capable of doing it, could somebody tell me how to cut out all the frames I don't want?

The above capture has one strange 2:2 cadence that ends at frame 29, and then it has 24 straight 3:2 cadences and then it has another 2:2 or 3:1, then it repeats.

Then when I made my first commercial cut of the clip at frame # 10000, I will have to determine the first 2:2 or 3:1 set after this. I'm just not familiar enough with how to use the ranges in avisynth. Is what I want to do worth doing and if it is, how would I go about doing it? I think the pattern is consistent enough that I shouldn't have sync problems.

New 'Men In Trees' last night, new pattern in it:

4:2 2:2 3:2 3:2 3:2 3:2

TDecimate(Cycle=30,CycleR=18) seemed to do a fairly good job on it.
