Aescripts Block Swap

Free Download Aescripts Block Swap for After Effects & Premiere full version standalone offline installer for macOS. Randomly shuffles image blocks. Great for clean-looking noise effects, blocky glitches, and transitions.

Overview of Aescripts Block Swap for macOS

How it works
Blocks of the source image are swapped between each other. Their size, spread, count, and other parameters can be controlled and animated.
Section Time Shift allows you to change blocks in time instead of just on the screen space.
If block swapping occurs, it can be controlled in the Mask Filter section with a few possible conditions to select, which is helpful to animate the in/out of the effect or have precise control over the placement.
Default values are backward compatible with the previous version 1.0.

Available parameters rundown

• Channels allow you to specify which color channels should the effect be applied to:
• RGBA - the effect is applied to all channels equally red, green, blue, and alpha - the effect is used only on the selected channel
• Block Width specifies the width of the blocks that should be swapped - the values go from 1 (this produces a noise-like effect) up to 4096 (large tiles)
• Block Height specifies the height of the blocks
• Shuffle Strength - the percentage of blocks that should be swapped. 0 - all the blocks remain in their original place; 1 - all the blocks are swapped.
• Shuffle Spread - how far apart should the swapping occur? 0 - swaps only the neighboring blocks; 1 - swaps blocks the furthest apart.

Shuffle Spread Direction determines the axis where swapping occurs:

• All - blocks are swapped anywhere in the image
• Horizontal - blocks are moved only in their rows
• Vertical - blocks are transferred only in their columns

Random Seed sets the order that's used for swapping. Animate this to move blocks around randomly.

Composite on Original controls whether to display the entire image or only changed parts. Useful to uncheck when you want to apply other effects only to areas where block swap was applied.

Time Shift

• Frame Count sets the number of frames on the timeline you wish to use in the Time Shift feature, with the ability to use up to 16 frames from a different time. If the value is set to 0, this feature is disabled.
• Probability defines the frequency of time-shifting occurrence. Value 0% turns off the feature entirely, and 100% means all the blocks are randomly time-shifted.
• Stepping Unit - the options Second and Frame specify which Time Step parameter is used. Sometimes, precise stepping by several frames is preferred, while control by time step in seconds guarantees stable stepping even when the FPS of the composition is changed.
• Time. Step [seconds] - specifies the time step per each frame in seconds from negative (backward) to positive (forwards) values.
• Time Step [frames] - specifies time step per frame in several frames and ranges from negative to positive values. Please keep in mind it's to your actual composition's FPS.
• Edge Time Mode - defines a strategy for handling access of frames outside the applied layer content boundaries. Repeat the Last pick in the first or the last frame. The Wrap option behaves like the layer was extended before and after by new copies of itself, which is ideal for looped footage. Setting Mirror acts as if the layer is extra copied before and after in the reversed direction.
• Exclusive Mode - when checked, time shift is only applied to blocks, and swapping in the screen space is omitted.
• Random Seed - sets the order used for randomization in the Time Shift section.

Mask Filter

• Provides better control over swapping occurrences. The Source image is a mask by default, but any other layer can be selected. Intensity controls how much the filter is applied. By default, it's set to 0% (no filtering) for backward compatibility.
• Intensity controls how strongly block filtering is applied. With the default value of 0%, the filter is not used.

Type offers three conditions to filter out swapping:

• The Threshold gradually filters out according to the luminosity intensity of the Mask Source in the same areas where swapping should occur. Regions with minimum luminosity filter out first, and areas with maximum luminosity stay even with 100% intensity.
• Randomized Threshold applies randomization of the Intensity parameter between 0 and maximum value, and then the Threshold is applied. This allows for a more natural disappearance of blocks when using gradients as a mask.
• Randomized Mask - The mask's luminosity is randomized between 0 and maximum value for each area, and then the filter is applied by comparing it with the selected Intensity. Again, it allows the other kind of natural filtering. An intensity value of 100% will filter all blocks for any mask given.
• Mask Source is a layer used for filtering (the default is a source layer for the effect).
• Random Seed sets the order used for randomization in the Mask Filter section.
