Help with telecined dvd

[shark_bloody]

Hi, I’m trying to deal with an uncommon source (for me), and can't figure it out. Is a hard telecined japanese dvd, when separating fields I get this pattern:

0 0 0 0 1 1 1 2 2 2 3 3 3 3 4 4 4 5 5 5 6 6 6 7 7 7 7 8 8 8 9 9 9 10 10 10 10 11 11 11 12 12 12 13 13 13 13

So, four of the same, then three of the same, and so on.

I've tried various things, and I keep getting repeating frames. Any suggestions are welcome, I'm always learning something new here.

Is that scene supposed to be slow motion?

[shark_bloody]

Yes, that scene is slow motion, I'll add another sample.

Here the pattern seems to be:

1 1 1 2 2 2 3 3 3 3

It looks like the "native" frame rate is about 18 fps. Probably 8mm film. This is pretty smooth:

TFM(d2v="sample.demuxed.d2v") 
TDecimate(mode=2, rate=18)

Or

TFM(d2v="sample.demuxed.d2v") 
TDecimate(Cycle=5, CycleR=2)

for 17.982 fps.

I noticed 1 dropped frame in each of those.

That worked very well, thanks jagabo.

Looking more closely at the video, I think it was originally 29.97 fps interlaced, bobbed to 59.94 fps, and finally reduced to about 18.088 fps by duplicating frames. Using DeDup() to remove the duplicates and assuming a frame rate of 59.94 leaves you with very smooth motion (no dups, no drops) at what appears to be a walking pace.

Mpeg2Source("sample.demuxed.d2v", CPU2="ooooxx", Info=3) 
TFM(d2v="sample.demuxed.d2v") 
#DupMC(log="dedup.txt")
DeDup(threshold=4.0, maxcopies=10, maxdrops=5, log="dedup.txt", times="times.txt")
AssumeFPS(60000, 1001)
