  Number of times the expression code is run in a composition?

  A very basic question

  How many times does the expression code run in a composition?

  If I have 5000 frames in a composition and I have placed the below code in a text layer, does the code run one for the life of the composition or does it run 5000 time, once on each frame.

  X = 5;
  X = X + 1;

  Since the result of your expression doesn’t change from frame to frame, the result may get cached–I’m not sure. But if your expression generates a new result on each frame it would have to be evaluated on each frame.
