  Editing multiple framerates

  Posted by Kevin Elam on February 3, 2008 at 11:00 pm

  Hello, sorry if this has been asked before, I’ve been unable to find an answer anywhere.

  I am putting together a demo reel of animation I have worked on. My source clips are all different framerates and sizes. 15fps, 24fps, 30fps, 23.97fps, and 29.97fps. Some clips are interlaced, which is another issue I need to figure out. (Is there an easy way to deinterlace just those clips for my final output?)

  My primary question: What is the best way to approach editing these clips together? What framerate should my Premiere project be setup at? 24fps or 30 or? The final edited project’s destination will be DVD and the web.

  Thanks!

  If these clips are going on a DVD, you could potentially encode each program into individual DVD-MPEG files. Digital Versatile Discs can hold multiple formats on one disk.
  So, you could drop the 30P to 29.97, and drop the 24P to 23.976 (with 15 I-frames), and up the 15P to 23.976. You can have 60i & 24P programs on one disc! – In wide & full screen. 🙂
  Again, you can make a DVD that holds: 60i full, 60i wide, 30p full, 30p wide, 24p full, 24p wide, and any other format that you DVD authoring software will support.
  I think this is a good solution as you will be able to reorder the clips as you see fit, and you will have individual MPEG files that you could easily drop into another DVD project, without having to re-encode or re-edit.
  Note – You can change a VOBs file extension to MPG and drop it right into another DVD project, nice’n’easy! 🙂

  But, to answer your question of putting all of the files into one timeline, just pick the format that you have the most source of, and use that as your target format.

  Deinterlacing is a whole ‘nother subject.

  You can do ‘field double’ deinterlacing in Premiere, but you lose half of your vertical resolution. But, it’s the fastest method…
  Right click on the clip in the timeline and select Field Options/Always Deinterlace.

  You could also do ‘field blend’ deinterlacing in Premiere.
  You would put two instances of the clip in your timeline, on layer 1 and on layer 2.
  Than, deinterlace both clips with opposing field orders by setting both clips to Always Deinterlace, than apply Reverse Field Dominance to one of the clips (it’s the checkbox above the Field Options).
  Than, set the opacity of the video in layer 2 to 50%.
  Make sure to turn the audio off on one of the clips before rendering with this method, or you’ll also double your audio.

  Certainly, there are better methods for deinterlacing, Magic Bullet or FieldsKit, especially if you have After Effects.

  For changing frame rates, I recommend Twixtor for After Effects.

  Hope this gives you some ideas.
