A catalog of 35 production-ready Adobe After Effects scripts, a dockable Build-a-Bar command bar — as both a ScriptUI panel and a native AEGP plugin — a client-side bundle generator, and a full test harness, organized as a monorepo.

The native Build-a-Bar plugin source (cross-platform C++/Obj-C++ AEGP, macOS + Windows) is maintained in a separate private repository; only its prebuilt binaries are distributed here, under
site/download/native/.
Three scripts remain in src/ but are excluded from distribution (the bundle, the Command Bar, and the website): Onionizer, PathDuplitron, and Split-o-matic_9x16.
| Script | Description |
|---|---|
| 2-3 IK Rigger | Select 2 or 3 layers and run it — they're wired into a working 2- or 3-segment IK chain. |
| PathMaster | Animate a layer's Position along any shape-layer path — retime, re-ease, trim, loop, or ping-pong. |
| Linearizer | Drive existing keyframed animation from any slider, position, or rotation value. |
| Limb-a-tron | Two-segment IK/FK limb rig — drag one null to bend it, tune everything from one controller. |
| Script | Description |
|---|---|
| Guiderator | Drop exact ruler guides by typing a number — or a formula like 1920/2 — into a dockable panel. |
| Slidotron_16x9 | One-click horizontal 4K slide-reveal rig — two nested comps with mirrored alpha mattes. |
| Slidotron_9x16 | One-click vertical 1080×1920 slide-reveal rig with mirrored mattes. |
| Verticalizer | Turn a landscape source into a rigged 1080×1920 split-screen portrait comp in one click — drag-handle framing plus a full styling panel. |
| Script | Description |
|---|---|
| ChromaBlenderizer | Ramp a color range across selected fills, strokes, and effect colors from a modeless palette. |
| sfxMaster | Mix Voice Over, SFX, and Music from three master sliders — audio layers auto-categorized. |
| BurstMate | Drop a fully rigged radial stroke burst — control color, length, density, and decay. |
| Sync-o-tron | Make any property audio-reactive in one click — TuneSync builds the Easing/Min/Max controls; ships with a template project that auto-imports. |
| Script | Description |
|---|---|
| Elast-o-matic | Add elastic overshoot or gravity bounce after any keyframe — hold Cmd/Ctrl at launch to switch variant. |
| KeyBot | Batch-edit selected keyframe values with =, +, −, ×, ÷ per axis. |
| KeyCloneMatic | Repeat a hand-tuned keyframe set down the timeline at a fixed or decaying interval. |
| Valuatron | Stamp a keyframe at the playhead for every selected property at once. |
| Script | Description |
|---|---|
| Controllerizer | Gather any selected properties from any layers onto one Controller Null as matching expression controls. |
| Opac-o-bot | Parenting for Opacity — selected layers' Opacity follows their parent via expression. |
| Reseterator | Zero the transform origin of selected layers — layer anchor to [0,0,0] and every nested shape group re-centered. |
| NullBot | Parent a group of layers to one master null at their average position. |
| Parent-o-bot | Blend a layer's Position, Scale, Rotation, and Opacity toward up to two parent layers. |
| Rectangulator | Convert a parametric rectangle into a bezier shape with independent per-corner rounding and a 9-point anchor grid. |
| OrderMaster | Reverse or shuffle the stacking order of a contiguous run of layers or shape groups. |
| SubtitleForge | Build a full caption rig — text plus a self-sizing box with stroke and drop shadow. |
| TextMate | Highlight every case-sensitive occurrence of a word in a text layer, each with its own animator. |
| TimeWarp-a-tron | Drive a layer's Time Remap from a 0–100 slider that scrubs a user-defined in/out range. |
| Script | Description |
|---|---|
| Centralizer | Drop center and bounding-box guides around anything — one shape, a multiselected group, images, or precomps. |
| VertexMaster | Turn a bezier path's vertices and tangents into keyframable, parentable null-object handles. |
| Distributron | Spread a comp's layers evenly along a shape path, each auto-rotating to follow the curve. |
| Originator | Recenter a shape layer's bezier path origin on (0,0) so it scales and rotates predictably. |
| Trace-o-matic | Convert a layer's masks into a new shape layer with hold-keyframed paths and opacity. |
| Script | Description |
|---|---|
| Iteratron | Spread a property evenly across a layer stack between a start value and an end value. |
| RandoMatic | Replace every selected keyframe's value with a fresh uniform-random number per axis. |
| Triminator | Add a pre-keyframed 0→100% Trim Paths reveal to a shape layer's contents. |
The Build-a-Bar command bar ships in two forms — a universal ScriptUI panel and a native plugin — both a single dockable toolbar with one icon button per bundled script.
packages/ae-scripts/toolbar/Build-a-Bar.jsx is a dockable, resizable ScriptUI panel. It reflows responsively (vertical, horizontal, or grid), reads tooltips from a bundled tooltips.txt, auto-discovers scripts from a sibling ivg-scripts/ folder, and swaps Shift- and Cmd/Ctrl-variant icons live. Install it in the After Effects ScriptUI Panels folder so only the Command Bar appears in the Window menu; the individual scripts live in the ivg-scripts/ subfolder and are launched from the bar. Runs in any AE version — no install beyond copying the folder.
A real native AEGP plugin (not a script or CEP extension) that draws the same bar with crisp vector icons at any size. On top of the panel it adds a customizable bar where you can drag to reorder the tools, change icon size, and recolor the icons to monochrome in any tint, with an orientation-aware Build-a-Bar logo. Prebuilt binaries for macOS (Apple Silicon + Intel) and Windows (x64) are offered on the website's Build-a-bar section and stored under site/download/native/. The plugin source is maintained in a separate private repository.
The site/ directory is a self-contained static site (vanilla HTML/CSS/JS) deployed to https://forge.mograph.life/apps/ae:
- Catalog — every distributed script with icon, purpose-first tagline, and a detail view.
- Docs — the full per-script documentation, rendered from
docs/scripts/*.md. - Build-a-bar — check the scripts you want, pick a format (ScriptUI panel, or native macOS / Windows plugin), and download a custom package containing Build-a-Bar plus your chosen scripts, assembled entirely client-side with JSZip.
site/tools/build-data.mjs parses each script's JSDoc front matter into scripts.json / meta.json, applies curated taglines from copy-overrides.json, and copies icons, docs, scripts, the toolbar, and the Sync-o-tron template project into site/ so the site is fully self-contained. site/tools/build-bundle.mjs rasterizes the toolbar icons and assembles the download zip.
tools/ae-test-harness runs the scripts through a layered ExtendScript-simulation pipeline (vitest):
- Static — ES3 parse via acorn (
ecmaVersion: 3) plus a scan for malformed@includepreprocessor directives. - Expression — AE expression syntax validation.
- Functional — sandboxed simulation against category fixtures in
tools/ae-test-harness/fixtures/. - UI — ScriptUI construction capture.
All 33 distributed scripts pass. Onionizer is excluded (external @include dependency).
- Copy the desired
.jsxfrompackages/ae-scripts/src/<category>/to your After Effects Scripts folder:- macOS:
/Applications/Adobe After Effects [version]/Scripts - Windows:
C:\Program Files\Adobe\Adobe After Effects [version]\Support Files\Scripts
- macOS:
- Restart After Effects and run via
File > Scripts > [Script Name].
Place Build-a-Bar.jsx in the ScriptUI Panels folder and its ivg-scripts/ subfolder alongside it, then open it from the Window menu. The Build-a-bar download on the website packages this layout for you.
Download the build for your platform (macOS Apple Silicon / macOS Intel / Windows x64) from the website's Build-a-bar section, drop the extracted IVGD folder into the After Effects Plug-ins folder (the download's INSTALL.txt has the exact path), and restart AE. Build-a-Bar then appears in the Window menu.
cd packages/cep-extensions/frame-navigator
yarn install && yarn build- Node.js 16+, Yarn (do not use npm), After Effects CC 2019+.
- Scripts target ES3 (no modern JS in
.jsx); use$.writeln()for debug output. - Each script carries versioned JSDoc front matter (
@version,@changelog) — the build reads this into the site. - After editing scripts or copy, run
node site/tools/build-data.mjs(data) andnode site/tools/build-bundle.mjs(icons + zip) to regenerate. - See CLAUDE.md for development context and constraints.
The site/ directory is deployed as an independent Vercel project (ae, root directory site/, production branch main). Pushing to main auto-deploys. The public URL is surfaced at forge.mograph.life/apps/ae via a rewrite in the forge hub, alongside the other apps (lerp, rav, etc.).
