Opacity fade in / out
Is there a expression so I don’t need to keyframe in a 10 frame opacity fade in / out which is controlled by the layers in / out point.
What I am trying to achieve is that whenever I change the layers in / out point it will always fade in for 10 frames and fade out for 10 frames at the given start point / end point. I know its lazy but it sure would speed me up!
Many thanks

Just found this, which is exactly what I need:
fadeInTime = .5; // fade in time (seconds)
fadeOutTime = .5;Math.min(linear(time,inPoint,inPoint + fadeInTime,0,100),linear(time,outPoint – fadeOutTime,outPoint,100,0))
PERFECT!

Hi, your solution sounds great – but is related to in / outpoint. I´d need this smooth changes whenever an object randomely meets a moving hotspot. Any idea how to start it independently from in / outpoint?
