  23.976 to 29.97 Interpret

  Posted by Gene Gemperline on April 16, 2008 at 2:34 pm

  So we’ve (my editor and I) got a problem here. I’ve got a bunch of Quicktime Movie clips with different frame rates that I’m trying to import into an NTSC AVID without it showing up steppy on the monitor. The project is 29.97, but some of the stuff we’re importing is 23.976. We’ve tried running the clips through After Effects and interpreting the footage to conform to 29.97, guessing the 3:2 pulldown, but then the audio falls out of synch. We’ve also tried bringing it into FCP and nesting it in a 29.97 sequence. That seemed to work a little better, but it still showed up steppy. We thought it was a field thing, and tried importing the clip with upper, lower, and no dominance. Nothing worked. What is the remedy for this? Any help would be much appreciated. Thanks.

  Try this:

  Remove 3:2 pulldown (telecine) using CinemaTools. FCP won’t do it. Read the Cinema Tools manual. Search for reverse telecine.
  24p involves not just duplicated frames but mix of frames as interlaced fields.

  24pa: This can be removed by FCP on the fly (advanced pulldown 2:3:3:2) when captured since it’s not dealing with mixed fields, it’s just dropping frames.
  If you don’t remove when captured you can remove it by selecting the clips and going to Tools >Remove Pulldown

  Found this in a DVX forum awhile ago.It helped me. Best of luck.

  You want to add 2:3 in order to make a 59.94 NTSC import. It should not change audio sync as long as you are sure the sources are 23.976 and your target is 29.97. If your sources are actually 24.000fps, then you need to slow down audio by .1% to maintain sync.
