  visible for 2 frames, gone for 4 frames ?!?!?

  Posted by Florian Herweg on July 6, 2010 at 12:28 pm

  i try to get a expression together that modifies the opacity of a layer. 100% for 2 frames. 0% for 4 frames.

  a good starting point was the searching the cow of course. i found this expression from dan and modified it a little bit.

  there = 100;
  gone = 0;
  f = timeToFrames();
  if (f%4 == 0) there else gone;

  i understand more or less whats going on here but i can’t get it to hold the 100% for 2 frames.

  any help is appreciated!

  good expression…

  another way would be to use the strobe light effect.

  set the ‘strobe’ property to ‘makes layer transparent’, then enter the values for duration and period.

  Thanks for the info, I just used expressions to do a quick test, the Strobe effect didn’t work for me:

  there = 100;
gone = 0;
f = timeToFrames();
if (f%2>0.5) gone else there;
