Random Crop

Presets contain a snapshot of your effect configuration. 50 built-in presets are available.

When you save parameter configuration to a file on disk, this file can later be loaded to recreate the same effect configuration. Presets generated in one video application can be used by the same plug-in running in a different video application.

The following options are available:

• Random (default) — No limitations are imposed on the aspect ratio of each randomly selected region. Separate Width and Height ranges are available to define the minimum and maximum size, along each dimension.
• Square — Each randomly selected region has square aspect ratio. For this reason, only the Width range is available. Based on each random choice in width, an identical height is used.
• Match clip — Each randomly selected region has the same aspect ratio of the underlying video. For this reason, only the Width range can be specified. The height is then chosen so that the aspect ratio of the cropped region is identical to the source media.

Defines the lower and upper bounds for the width of each randomly selected region. The range is expressed as a percentage of the frame. For example, if the lower bound is 20% and the upper bound is 80%, a random width for an HD frame (1920 pixels wide) will be chosen between 384 and 1536 pixels.

If you are unhappy with the sequence of randomly-selected regions, assign a new value to the Seed parameter under the Animation section. Each seed produces a unique, but reproducible sequence of random dimensions.

Defines the lower and upper bounds for the height of each randomly selected region.

This range is only available when the Aspect Ratio parameter is set to Random, which allows the height of each randomly selected region to be arbitrarily chosen.

The following options are available:

• Dissolve (default) — A simple cross dissolve.
• Pan — The current region is scaled and translated to the location and scale of the next randomly selected region.
• Push — The current region is pushed outside the frame, as the next randomly selected region slides into the frame.
• Flip — The current region is flipped to reveal the next region on its backside.
• Cube — The current region is rotated in 3D as if to reveal the next region on the next face of a simulated cube.

The following options are available:

• None (default) — No mask is applied to each randomly-selected region.
• Star — Each randomly-selected region is masked through a configurable, animatable star shape.
• Text — Each randomly-selected regioin is masked by a title of your choice, edited and customized through an external editor.
• Custom graphic — Allows you to provide a black and white image to be used as a mask, where white pixels define the visible portions of the mask and dark pixels define the invisible portions.

The following options are available:

• Round — default
• Bevel

Allows you to select a black and white graphic to be used as a mask. This parameter is only available when Shape is set to Custom graphic.

White pixels in your graphic file control the visible portions of your media, black pixels control the invisibile portions.

Controls the visibility of the original media, behind the cropped regions.

If needed, you can reproduce the output of older versions of this plug-in by setting this value to 0%, hiding the background entirely.

The following options are available:

• Color Adjustment (default) — Enables additional Exposure, Saturation, Brightness and Contrast parameters to apply a color adjustment to the original media visible in the background.
• Duotone — Applies a two-tone colorization to the original media. You can map highlights and shadows to the colors specified by the Color 1 and Color 2 parameters.

Turn this parameter on to animate the Star Angle parameter.

Turn this parameter on to animate the Push Direction parameter.

Push Direction Animation

A number that controls random aspects of the effect.

Click the New button to assign a new seed value. When the seed value is changed, the effect uses a different random sequence to produce a different output.

Edit the existing value to manually assign a seed number. This may help you replicate a particular sequence of random events. In Final Cut Pro and Motion, hold down the Option ⌥ key to access the Edit button in the inspector.

Enables motion blur at different quality settings. The higher the quality, the more samples are used. Multiple samples are blended together to produce a single frame of output.

• Off (default) — Output frames are rendered without motion blur. This is the fastest setting.
• Low
  Combine 4 samples to produce each output frame.
• Medium
  Combine 8 samples to produce each output frame.
• High
  Combine 16 samples to produce each output frame. This is the slowest, highest quality setting.

Multiple samples are combined to produce a single output frame with motion blur

The Shutter Angle slider controls the size (aperture) of the shutter used to simulate motion blur. The size of the shutter determines how long light is allowed to pass through the lens. The angle is set to 180° by default. A shutter angle of 360° means that samples are collected for the entire duration of the frame.
Setting a value of zero means that you want the shutter to collect light only once, which is equivalent to turning motion blur off.

The Shutter Offset slider controls the moment in time when the shutter opens and closes, relative to the duration of the frame. The offset is set to 0 by default. An offset of zero means the shutter is perfectly centered over the moment in time when the frame occurs. The shutter is therefore open an equal amount of time before and after the current frame occurs.

The Shutter Angle and Shutter Offset parameters are only available when motion blur is enabled.
