  Probably something like this:

  
if (time < (inPoint+outPoint)/2)
linear(time,inPoint,inPoint+thisComp.frameDuration,0,180)
else
linear(time,outPoint-thisComp.frameDuration,outPoint,180,0)

  thank you Dan . Expressio work fine , parameter changes , but ! strangely enough, it works in the beginning of the clip but does not work at the end of clip . I even tried to do at the end of – 2 frames
  else
  linear(time,outPoint-thisComp.frameDuration*2,outPoint-thisComp.frameDuration,180,0)
  but to no avail
  on keyframes , it work fine . maybe it’s a bug AE
