Flip Axis Specifies the axis around which each card flips. Choose an axis for precision flipping, or Random for a more
realistic effect.
Flip Direction Specifies the direction in which the cards flip around their axes. With the x axis selected, Positive flips
thecardsupandNegativeflipsthemdown;withtheyaxisselected,Positiveflipsthecardstotheright,andNegative
flips them to the left. Selecting Random randomly flips positively or negatively.
Flip Order Specifies the direction the transition occurs. For example, Left to Right starts the cards flipping on the left
and proceeds to the right. You can also use a gradient to define a custom flip order: Cards flip first where the gradient
is black and last where the gradient is white.
Gradient Layer Specifies the gradient layer you want to use for the Flip Order. You can use any file in the compo-
sition (visibility can be turned off).
Timing Randomness Randomizes the timing of the transition. When this control is set to 0, the cards flip with
precision. The higher the value, the more randomly the cards flip and the more realistic the effect.
Random Seed Generates a unique result for random effects. True randomness is not repeatable; if effects were
genuinely random, you couldn’t go back and fine-tune part of an effect without rerendering. However, two random
effects running next to each other may look noticeably alike. To avoid this, use a random seed. A random seed is a
number that is inserted into the calculation to generate a unique result. By changing the Random Seed setting, you
can make effects using the same settings appear different.
Camera System Specifies whether to use Camera Position, Corner Pins, or Comp Camera. Comp Camera tracks the
composition’s camera and light positions and renders a 3D image on the layer.
Camera Position controls for the Card Wipe effect
X Rotation, Y Rotation, Z Rotation Rotate the camera around the corresponding axis. Use these controls to look at
the layer from the top, side, back, or any other angle.
X, Y Position Specifies where the camera is positioned in (x,y) space.
Z Position Specifieswherethecameraispositionedinzspace.Smallernumbersmovethecameraclosertothelayer,
and larger numbers move the camera away from the layer.
Focal Length Specifies the zoom factor. It is like a camera’s zoom lens. Smaller numbers zoom the camera lens out,
and larger numbers zoom the camera lens in.
Transform Order Specifies the order in which the camera rotates around its three axes, and whether the camera
rotates before or after it is positioned using the other Camera Position controls.
Corner Pins controls for the Card Wipe effect
Corner Pinning is an alternative camera control system. Use it as an aid for compositing your layer into a scene.
Upper Left Corner, Upper Right Corner, Lower Left Corner, Lower Right Corner Specify the location of each of the
four corners of your layer.
Auto Focal Length Controls the perspective of the effect during the animation. When Auto Focal Length is
deselected, the focal length you specify is used to find a camera position and orientation that positions the corners
of the layer at the corner pins. If this isn’t possible, the layer is replaced by its outline, drawn between the pins. When
Auto Focal Length is selected, the focal length required to match the corner points is used, if possible. If not, it inter-
polates the correct value from nearby frames.
Focal Length Overrides the other settings if the results you’ve obtained aren’t what you need. If you set the Focal
Length to something that doesn’t correspond to what the focal length would be if the pins were actually in that
