  Converting 30 fps playable DVD to 24 fps Quicktime

  Posted by Addie Donnell on December 11, 2012 at 6:40 pm

  So, this is a problem that I deal with quite a lot, but my usual work around is unavailable this time. I am given a 4×3 Letterbox DVD with a 30fps vis TC. I am suppose to take this picture and convert it to
  720 x 480
  23.98
  TC burnt in
  MJPEGA

  Every time I do it, there are duplicate frames, which obviously will not fly. My current process is, ripping the DVD with mpeg streamclip as a Apple ProRes 422, importing into FCP in a 23.98 sequence, putting VIS TC, exporting, then compressing with Mpeg streamclip to the appropriate specs. There are always duplicate frames. Is there a way to get around this problem?

  Any help would be amazing! Thanks!

  What would that be?

  Is your source 23.98 in i59.94?
  You’d want to do a inverse telecine to properly remove the pulldown. The software doing that would have to properly detect the cadence of course. Telestream Episode might be able to do this.

  Usually, I have te CTM to marry to the M & E’s to export and compress, boom, done. But I don’t have that today. I will try and investigate Telestream Episode, I suppose.

  Thanks for you help.
