What It Does
Blend creates animation systems where you define two states (start and end controllers) and the script automatically interpolates the difference across a specified number of objects. The basic system handles position, rotation, scale, and opacity. You can add any keyframeable property to the blend, from trim paths and stroke colors to custom shape layer properties.
The tool includes a delay system that staggers the animation timing across your objects, useful for creating follow-through effects or cascading transitions.
Key Features
Start and End Controllers. Set two property states and Blend distributes the interpolation across your objects. Works with parented and 3D layers.
Blend Controls Effect. Adds a controls panel to your blend system with delay controls and an Adjustment slider. The slider moves blended objects between the start and end positions, letting you animate the overall blend state.
Even and Reverse Delay. Two checkboxes in the controls determine how delay propagates through the system. Combine these with the delay amount for different stagger patterns.
Add Any Property. If a property can be keyframed, it can be added to a blend system. Trim paths, fill colors, stroke widths, or effect parameters all work.
Stroke Width Control. A checkbox maintains consistent stroke widths across blended objects, preventing thickness distortion during transforms.
Dynamic Object Count. Duplicate layers with Cmd+D (Mac) or Ctrl+D (Windows) to add more objects to the blend. Delete layers to remove them. The system updates automatically.
Who It’s For
Useful for motion designers working with repetitive animation patterns. Title sequences with staggered text reveals, shape layer morphs across multiple elements, or abstract motion graphics with coordinated transitions all benefit from this approach. The ability to add custom properties makes it adaptable to different workflows.
Some experience with expressions and master properties helps you extend the system beyond the basics, though the core functionality works without scripting knowledge.
Pricing
Blend uses pay-what-you-want pricing (currently $15 suggested). A trial version is available but restricts you to basic blend systems without additional property support. If you purchase after using the trial, you’ll need to recreate existing systems to unlock full functionality.
Compatible with After Effects CC 2019 through 2025.
