  Problem with keyframes

  Posted by Petr Berger on September 22, 2010 at 4:05 pm

  I have a text animation with few keyframes. There are two keyframes with the same values and between them the text should be steady, but its not. Its scaling up and then down, like there is another keyframe between them, but there is no keyframe! Really weird. I try to delete those keyframes and create it again, but the problem persists. Maybe I’m missing something?

  I just found the solution. Its called keyframe spatial interpolation. I dunno what it is, but I changed i to linear and now its ok.

  Yep, you encountered the boomerand effect. Setting the keyframe to linear or adjusting the bezier curve points alleviates the problem.
