With this iExpression you can move a 2D layer in and out of screen using a uniformly accelerated movement in any direction. At first sight the motion might seem similar to using 'easy ease' keyframes, but due to the uniform deceleration when moving in and uniform acceleration when moving out, the movement is slightly different and more natural.

• Acceleration

  determines how fast the object decelerates when moving in and accelerates when moving out.

• Angle In

  

  is the Angle (i.e. the direction) from which the object is moving into the frame. 0 = from the top, 90 = from right, 180 = from the bottom, 270 = from left

• Angle Out

  is the Angle (i.e. the direction) in which the object is moving out of the frame. 0 = move up, 90 = move to the right, 180 = move down, 270 = move to the left

• Move In Time

  Move In At

  controls whether a movement into the frame should be enabled and if so at which point in time this movement should be finished (at the first keyframe, an a manually chosen keyframe, at a manually chosen frame, or no movement into the frame at all).

  Move In (Key) Frame No.

  is the frame or the keyframe (depending on the choice of 'Move In At' option) at which the movement into the frame should be finished. If 'Move In At' has any other value than 'keyframe no.' or 'frame no.' this value is ignored.

• Move Out Time

  Move Out At

  controls whether a movement out of the frame should be enabled and if so at which point in time this movement should start (at the first keyframe, an a manually chosen keyframe, at a manually chosen frame, or no movement out of the frame at all).

  Move Out (Key) Frame No.

  is the frame or the keyframe (depending on the choice of 'Move Out At' option) at which the movement out of the frame starts. If 'Move Out At' has any other value than 'keyframe no.' or 'frame no.' this value is ignored.
