  1. hi,

    i'be here one of my favorit cartonns and i try to restore the originale frame rate. i've bobbed the source and created the following notaion

    Code:
    aaaa bbbb cccc dddd eeee ffff gggg hhhh iiii jjjj kkkk llll > ll
    the video is 23.976 so after bobbing it's 47,952. as you can see every frame is shown 4-times instead the l-frame, its shwon 6-times (the last 2 l-frames belongs to the next second). the original frame rate should be 12fps. there are no blends so i've tried this

    Code:
    tfm().tDecimate()
    but the resulting (new) frame rate is 19.181 and this can't be right. after that i've tried

    Code:
    yadif(mode=1).tdecimate(mode=2,rate=12.500)
    it doesn't work with rate=12.000 (error: mode 2 error: unable to achieve a completely synced result). is there any other way to restore the originale frame rate? any idea? i don't know whether uploading an example can be problematic because of the copyright.

    now i want to sync the video with the audio from a tv capture in my language. the capture's frame rate is 25. how can i get the same frame rate for my video? just another bobbing? yadif(mode=1) results in a framerate = 25.001.

  2. A sample is called for. But a duplicate field every 12 frames indicates 24 fps film that was telecined as PAL video with 2:2:2:2:2:2:2:2:2:2:2:3 pulldown. Then somebody probably slowed the PAL video to 23.976 fps for NTSC.

    Try something like:

    Code:
    # assuming interlaced source here
    Yadif(mode=1, order=N) # to 47.952 fps
    AssumeFPS(50)
    TDecimate(cycle=50, CycleR=26)

  3. Keep it at 23.976fps. As is typical with animations, all sorts of framerates are used. This sample has some real 23.976fps content. Just advance a frame at a time beginning when the guy is walking, at about the six second mark. Every frame has movement.

    A sample of that one would be needed. Most likely, as jagabo said, they just added a frame every second so you just remove it. You'd decimate to 23.976fps, as this sample is.

  4. I wasn't able to download the file but it sounds like manono is right.

  5. What means order in yadif?

    You could try reading the manual for the answer:

    order = -1 : field order as Avisynth assumes (default).

    = 0 : Bottom field first.

    = 1 : Top field first.

    If you choose one and it's the wrong one, then you'll get this herky-jerky back-and-forth movement when advancing the video. If you're asking because of your 25fps video for which you want the audio for your 23.976fps video, you had best provide a sample. There's a fairly good chance you can just use the audio for the 23.976fps video without doing anything except perhaps adding a delay. Have you compared the lengths of the two videos yet?

  7. i've encoded and synced the video without changing the frame rate and thats ok.

    but there's an other question: when i write down the image types (clear image, blend or duplicate) and determine the originale frame rate the second ends between blends, something like this:

    a a b b ... n n o o > o o
    the second ends after the second o-frame. lets say n is the 12. frame - whats with the 2 o-frames in the following second? is the original frame rate now 12,5fps? with comics artist paints a half frame?

  8. I explained that in post #2. It's the result of using pulldown to convert 24 fps to 25 fps. Essentially 12 frames becomds 12.5 frames, hence 24 frames becomes 25.

  9. @ jagabo

    thanks, i'll tried you example.

    i've an other vidoe here with runs very good, but for some seconds i've a lot of blends (2 or 4 double blends after bobbing the source). this is only for some moments, before and after that the videos runs normally with blends. i don't think there is a filter that can fix double blends?

    http://www.share-online.biz/dl/WPDZ1BAOVRKV

    maybe - because the scence isn't very long - i can delete the blends manually. but after that the frame rate is less then the rest of the video. do i need to use a fps filter or just replace the blends with a another clear frame using duplicateframe?

  10. I don't know any automated way to remove all the blended frames from that clip.
