  1. Hi, Iím 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?

  3. 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

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

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

    Code:
    TFM(d2v="sample.demuxed.d2v") 
    TDecimate(Cycle=5, CycleR=2)
    for 17.982 fps.

    I noticed 1 dropped frame in each of those.

  5. That worked very well, thanks jagabo.

  6. 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.

    Code:
    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)
