  Combining Expressions as Sets

  Posted by Kevin Kefgen on May 29, 2006 at 12:57 am

  It’s a lazy Sunday afternoon, and I figured I’d kick around the COW for awhile, and I came across Joel Hooton’s tutorial expounding on Dan Ebberts’ about synching audio and video. After testing, I liked it a lot… One question, though… At the end of the Hooton tutorial, he says you can combine them and get cooler, more scalable (for lack of a better word) effects. My simple minded question is… How?

  How does one go about taking an expression like the Ramp Up in the tutorial (#1, I believe):

  if (marker.num_keys > 0){m = marker.nearest_key(time).index;
  if (marker.key(m).time <= time){ (1/(marker.key(m+1).time-marker.key(m).time))*(time-marker.key(m+1).time)+1 }else if (m != 1){ (1/(marker.key(m).time-marker.key(m-1).time))*(time-marker.key(m).time)+1 }else{ 0 } }else{ 0 } and make a set out of that, so you can ^2*45 (for a rotation move) or *100 for an opacity? Or am I being overly optomistic about this? Any hints? Thanks for reading! Kevin Kefgen Edit Guppy Post Production Las Vegas, Nevada
