ABSTRACT

Even when your final output is to video, you will want to animate at 24 fps. At some point in your digital compositing or nonlinear editing, you will do a 3 :2 pulldown, or telecine, of your animation, which converts your frame rate from 24 fps to 30 fps. You can only use telecine on your scene when exporting to a video file in a format such as AVI or MOV (Windows and Mac video file extensions). Exporting to frames does not allow you to telecine. The reason for this is that telecine uses the upper and lower fields of video to stretch the footage, and exporting frames does not incorporate fields. (In some programs you may set the Time Stretch to 125% or the Clip Speed to 80% [30/24 = 80] to create the same effect and still export to frames; see Figures 1-1 and 1-2.) When you convert from 24 to 30 fps, you won’t see a difference in the look of your animation. If you think about it, all features, live and animated, are shot at 24 fps on film and are released on video at 30 fps, and you can’t tell the difference.
