The Auto Transition Builder for After Effects, available on aescripts + aeplugins, is a workflow extension designed to automate the often tedious process of adding transitions to multiple layers. Core Functionality

The script addresses the repetitive nature of manual video editing by allowing you to apply transitions to an unlimited number of layers simultaneously. Its primary purpose is to speed up the creation of montages, slideshows, or complex motion graphics projects where dozens of cuts require seamless blending. Key Features

Mass Automation: Apply unique or randomized transitions to a large volume of layers in seconds rather than minutes.

Custom Library Integration: Unlike standard "preset packs," you can add your own custom-made transitions to the extension.

Smart Resize: When importing your own transitions, the script uses a "smart resize" feature to ensure they fit the current composition's dimensions automatically.

Persistent Packs: You can organize your transitions into custom packs, save specific selections, and load them permanently for future projects.

Visual Previews: The extension includes a preview grid where you can click a transition to add it instantly with one click. Workflow & Use Case

The typical workflow involves selecting your desired layers in the After Effects timeline, choosing your transitions from the extension's panel, and clicking "Run". The script then automatically calculates the overlap and applies the necessary effects or pre-compositions to bridge the layers. This tool is particularly useful for:
