AlphaForge

Procedural mattes, graphics & transitions — generated in seconds.
AlphaForge is a procedural generator for After Effects that builds animated mattes, graphic elements, and transitions right inside your comp. Pick a mode, dial in a few controls, and AlphaForge does the rest — fully non-destructive, endlessly variable, and render-ready. Built for motion designers and editors who need broadcast-quality reveals and backgrounds without hand-keyframing a single shape layer.

Randomizer · 200 presets

One click, infinite on-brand variations

Hit Randomize and AlphaForge reshuffles into a brand-new, coherent matte — counts, timing, and motion shift together while staying on-brand. Browse 200 presets across grids, waves, scatters, wipes, and radials, lock a seed you like, and it's reproducible forever.

Mattes · Graphics · Transitions

Reveal, composite, transition — all editable

Generate animated track mattes for reveals, full-color graphic elements, or ready-to-use transitions between two clips. Here a matte reveals a portrait over a second shot — and every layer stays a native, editable After Effects layer.

AlphaForge control panel — animation, count, duration, stagger and easing curves
Direct control · 20+ parameters

From three sliders to total control

Start with the core sliders — Count, Duration, Stagger — then refine across 20+ parameters spanning Timing, Transform, Effects, Echo and Color. Simple to start, deep when you need it.

Two ways to work

  • Dynamic — fast, randomized results you can reshuffle endlessly
  • Signature — precise, hand-tuned looks you can save and recall

Built for iteration

  • Non-destructive Rebuild — change anything, regenerate in place
  • Favorites & keyboard shortcuts
  • Dockable panel that lives in your workspace

Version History

1.0.1 -

Jul 6, 2026

- Fixed: the Name field in the Create dialog now names the generated comps and folder (e.g. typing "Hero" produces Hero_Result / Hero_Source / Hero_Matte). Leaving it blank keeps the preset name, as before.
- Fixed: the Intensity slider is now hidden for the Punchy style in Procedural mode, where it had no visible effect. Unchanged for Elastic, Bounce, and Snappy, and for all styles in Designed mode.
