  1. Hi there, I have an episode of a show that was cut in 23.976 and I'm wondering which might be the best way to apply 3:2 pulldown for broadcast/home video. Would I be better off just slapping the whole thing (as one video) into a 1080i/29.97 timeline and exporting it or using the original clips and basically copy and pasting the shots from the 23.976 timeline into a new one?

    I notice that when I use it as one video, some of the cuts end up having a field showing one shot and one field showing another.(see interlacing example.jpg)*

    If I use the shots directly on the timeline, I can avoid that, but does that mess up the cadence?

    Thanks in advance for any help!

    *(Note, the examples used are stock footage, I can't show the real thing I'm working on.)

    Why change the frame rate?
    Recent TV's have no problems at all playing 23.976 directly - they deal with any necessary frame repetitions them themselves

  3. It's a required deliverable for broadcast.

    And what are the rest of the video deliverable requirements?

    I think you just have to add it to a 29.97 project and allow Premiere to adjust the frame rate

  5. If pulldown is added after the progressive edits are finished, the cadence will be perfect. Just nest it into another 1080i/29.97 sequence.

    The problem occurs when you edit on a 1080i timeline and break up the cadence - instead of removing pulldown first and editing on a progressive timeline

    This is about what I figured, just wanted to be sure. Just wondering if there is a problem if I have one cut that has one set of fields displaying one shot (the coin in the attachment above) and the next set of fields displaying the next shot (the man) is that problem? Is there a way to avoid that or am I making a fuss about nothing?

    No problem if you didn't edit it afterwards. The cadence will be fixed. This appearance is normal when there is an odd number of frames on one of the scenes of the scenechange

  8. BTW make sure you it set to duplicate (frame repeats) , not blend or optical flow

    You can double check the result in AE with pulldown removal . Check the scene changes, they will look fine. It's a set pattern IVTC , and one of the 5 should work. AE cannot do adaptive field matching. It should give same result as the "23.976p" pre nested sequence

    Or you can check with this avisynth manual IVTC function; again set pattern IVTC for the "p" value between 0-4 . AssumeTFF for 1080i

    Code:
    function manualIVTC(clip v, int p)
    {
    	v=loop(v, p, 0,0)
    	v=v.SeparateFields().SelectEvery(10, 0,1, 2,3, 5,6, 7,8).Weave()
    	v=trim(v,int(p*3/5),0)
    
    	return v.assumeFPS(24000,1001)
    }
