Pinches, stretches and slides the input image.

This distortion can be used to simulate the window-minimizing and maximizing behavior used by the Dock UI in Mac OS X.

Effect Parameters

Presets
Presets contain a snapshot of the plug-in parameters. The Presets control lets you choose among one of the presets built into the plug-in, save current parameter values to a preset file, or load an existing preset file from disk.
A preset file saved to disk via the "Save As" button can be loaded from another instance of the same plug-in by clicking the "Open" button. Presets generated in one host can also be loaded from the same plug-in when used in a different host.

Distortion

Distortion
The type of distortion applied to the clip. The available options are:

• Slide: this option causes the image to be stretched as it reaches its final location.
• Squeeze: this option causes the image to be shrunk as it reaches its final location.

Squeeze In/Out
When the current “Distortion” setting is “Squeeze” this parameter becomes visible and lets you further refine the animation. To squeeze the source media to a location within the original frame, remember to set the value of the “Pinch Offset” parameter below to zero.

Angle
The direction in which the animation progresses. When the current “Distortion” parameter setting is “Slide”, the angle also determines whether the effect is aligned to the horizontal or vertical axis.

Pinch Amount
The maximum amount that the source media will be pinched as the animation progresses.

Pinch Offset
The location in the source media where the pinching distortion occur, relative to the current direction of the effect.

Magnitude
The total distance traveled by the source media during the animation, which will affect how and where it will be distorted.

Animation

Animation Time

This parameter lets you choose a method for timing the animation (its duration and progress):

• Duration of the clip - default option

  When this option is selected, the animation will progress in sync with the length of the clip to which the effect is applied.
  The animation begins and ends according to the current values of the Start At and End At parameters, specified as percentages of the total clip duration.

• Duration in seconds

  When this option is selected, the animation is driven by two parameters: Start Time and Duration. The parameters let you specify, in seconds, when to start the animation and how long it should last.

• Progress (animate with keyframes)

  When this option is selected, the overall progress of the animation is driven by a single Progress parameter. Add keyframes to this parameter to have the finest control over the animation's progress.

Animation Curve

This parameter controls the interpolation function used to drive the animation. The animation curve determines how fast (or slow) the animation will progress from its beginning to its end. The basic option, "Linear" translates to a uniform progression from the beginning to the end. All other options cover a wide range of common animation styles.

Linear	Quadratic In	Quadratic Out	Quadratic In-Out
	Cubic In	Cubic Out	Cubic In-Out
	Exponential In	Exponential Out	Exponential In-Out
	Sinusoidal In	Sinusoidal Out	Sinusoidal In-Out

This parameter is only available if the Animation Time parameter is set to "Duration of the clip" or "Duration in seconds". An animation curve can be derived only when the plug-in knows the exact duration of the animation. When the "Progress (animate with keyframes)" option is selected, you have complete control over the animation and are thus responsible for creating your own interpolation curves between each keyframe

Start At (% of clip) and End At (% of clip)

These parameters, available when the Animation Style parameter is set to “Duration of the clip”, let you pick a start time and end time of the effect specified as a percentage of the duration of the entire clip. A value of 0.2 for the Start At parameter means that the animation will begin 20% into the clip (for a clip that lasts 10 seconds, the animation would start 2 seconds into the clip.)
Using relative measurements rather than time units may guarantee some additional flexibility to your timeline, should you decide to resize the length of the clip. If you prefer to use actual time units, please set the Animation Time parameter to “Duration in seconds” instead.

Start Time (secs) and Duration (secs)

These parameters, available when the Animation Style parameter is set to "Duration in seconds", let you pick a start time and duration of the effect.

Progress

This keyframeable parameter, available only when the Animation Style parameter is set to "Progress", lets you control the overall progress of the animation

Start Sliding At (%)
The relative time, as a percentage of the entire animation, when the source media will begin sliding (or squeezing) to its final destination.

Stop Pinching At (%)
The relative time, as a percentage of the entire animation, when the source media will stop being pinched. This is also when the “Pinch Amount” parameter value is reached.

Reverse
Reverses the animation, so that the image slides in, rather than out of the frame.

Motion Blur

Quality

Enables motion blur at different quality settings. The higher the quality, the more samples are used to render the final scene.

• Off - the scene is rendered without motion blur.
• Low - render a few samples per frame.
• Medium
• High - render with the highest number of samples (slowest setting, highest quality)

Figure: motion blur with four samples per frame, a shutter angle
of 180 degrees and a shutter offset of 0.

Shutter Angle

When motion blur is enabled, this parameter controls the size of the shutter used to simulate motion blur. The size of the shutter determines how frequently light is allowed to pass through the lens. A shutter angle of 360 degrees means that samples are collected for the entire duration of one frame. Setting a shutter value of zero means that you want to collect light only once, which is equivalent to turning motion blur off.

Shutter Offset

When motion blur is enabled, this parameter determines the time when the shutter will open and close, relative to the current frame time.
An offset of zero means the shutter is open an equal amount of time before and after the current frame time.
