Change from one footage source to the next using a modifiable shape of your choosing. Shape Wipe allows you to control its position, direction, stroke, and other properties to get the look just how you want.
Presets
Use the Shape Wipe presets to streamline your form-centric A-B transitions. Simply keyframe the Mix duration (see below) and tune to taste! Find these presets via the blue Open Dashboard... button or the Choose a Preset... button below it.
As with all other Universe tools, you can modify or create a Shape Wipe look and then save it under its own name by pressing the Save Preset... button.
Getting Started in a Timeline
Drag the transition over your edit in the timeline, placing it at the end or beginning. Alternatively, you can place it between two successive clips.
Modify the
Duration
of the transition either by entering a length in the field or dragging directly in the timeline.
You can choose the
Alignment
(Center at Cut, Start at Cut, End at Cut, or Custom Start) either by positioning the transition in the timeline or by choosing from the Alignment drop-down in some host applications.
Getting Started in a Compositor
Apply the transition to the layer from which you want to transition.
Choose the footage layer you would like to transition to in the
Transition B
drop-down menu.
(Note for Motion users:
Drag the footage layer up to the Transition B box.)
Animate your transition using the
Mix
slider from 0% to 100 percent. Set a keyframe for 0% where the transition should start, then set another at 100% for the end.
Modify the Transition
Shape
contains a drop-down list of four basic shapes which determine the wipe shape: Star, Circle, Square, and Rectangle.
Shape Options
contains a list of controls that are dependent on which shape you selected from the
Shape
menu (above).
Rectangle Width
controls the width of the
Rectangle shape.
Below, you can see how we raised this value considerably.
Rectangle Rounding
rounds the corners of both the
Rectangle
and
Square
shapes.
In the above image, we maxed out this value at 100.
Star Inset
adjusts the concavity of the
Star
shape's inner corners.
In the following examples, we show 0.4 (the minimum, left), 0.6, and 1.0 (the maximum, right). Note how this last value turns our five-pointed star into a decahedron.
Star Points
determines the number of points in the
Star
shape.
Position
controls where the shape is located during the transition.
Compare the animation at this page's top, which leaves Position fixed in one place, with the below keyframing of Position from left to right across the scene.
Start Angle
controls the shape's angle at the transition's beginning.
Rotation Speed
dictates how quickly or slowly the shape rotates during the transition.
In the following comparison, we set Position at the comp's center, then we set Start Angle and Rotation Speed both to zero. Thus, only the size (Mix) animates over the transition time, allowing the B-clip shape to grow from nothing to filling the whole screen.
Reverse
will swap the footage inside the shape with footage outside the shape.
Note that the Mix flow also reverses, so your shape size shrinks over the transition.
Edge Softness
controls the blur along shape edges.
Enable Stroke
enables a line bordering the shape.
Inner Stroke Color
and
Outer Stroke Color
adjusts the color of the Inner
and Outer Strokes, respectively.
The arrows in the image below show which is which.
Inner Stroke Width
and
Outer Stroke Width
control the width of the Inner and Outer Strokes, respectively.
Note that the only difference between the
Inner
and
Outer Strokes
is that the
Inner Stroke
occupies the center of the
Outer Stroke. Increasing the Inner Stroke Width "pushes" the outer stroke further outward.
Stroke Blend Mode
adjusts how the stroke is composited over the source footage, with standard blend modes available from the drop-down menu.
In the above image, we used Screen to achieve that light translucency. Compare that to the Normal blend shown here.
Stroke Glow
toggles an optional glow emanating from both the
Inner
and
Outer Stroke.
Glow Intensity
adjusts the brightness boost of the
Inner Stroke Glow.
Glow Radius
controls how far the
Stroke Glow
tapers out from the
Inner
and
Outer Stroke.
In the following comparison, we show the default values of Glow Intensity: 2 and Glow Radius: 4 (left) versus Glow Intensity: 4 and Glow Radius: 16 (right).
Glow Noise
adds or removes optional fuzziness to the
Stroke Glow.
