Real plugin · captured inside After Effects

The status quo

AI video lives in a browser tab.

Generate in a web UI. Wait. Download. Re-import into the comp. Re-time to the soundtrack. Notice the second-to-last shot is off. Open the browser. Repeat.

The round-trip costs hours per scene and breaks the version control of a real production. The model is powerful, but the editor isn't where the model lives.

Justae closes the loop inside After Effects, where your scene, your timing, and your sound already are.

What Justae does

Three primitives that fit a real production.

Built around the way motion designers actually work, with markers, layers, and comps. Not the way a web UI thinks you should work.

Marker

AI interpolation across layers, in batch.

Drop markers on two or more video layers. Justae generates the in-betweens, with the model of your choice, in one queue. No one-shot prompt windows. No re-import.

  • Batch across an arbitrary number of markers
  • Per-marker retry without re-rendering siblings
  • Reference frame, length, and seed controls
  • Markers as the source of truth for timing

Storyboard

Drop placeholders. Get a timeline.

Lay down empty layers as placeholders. Write a prompt per layer. Attach references. Justae fills the comp, keeping your timing intact.

  • Per-layer prompts and reference images
  • Regenerate a single shot without breaking the comp
  • Prompt history kept per layer, per project
  • Works with any aspect ratio your comp uses
Asset pipeline

Files named the way a studio names files.

Every generation is versioned and named, automatically. Variants live next to their source. Nothing ends up in Downloads. Nothing breaks when you ship the project to an editor downstream.

  • Deterministic, comp-aware naming convention
  • Version chains: every retry preserved, never overwritten
  • Render-queue ready folder layout
  • Prompt + seed embedded as metadata

Keyboard-first

Shortcuts for every common action: generate, retry, accept, reject.

Soundtrack aware

Snap marker timing to audio peaks already in your comp.

Prompt history

Every prompt is logged per layer. Diff and roll back instantly.

Headless render

Queue batches to run while you sleep. Resume cleanly on wake.

How it works

Four steps. None of them leave the comp.

  1. Step 01

    Lay out placeholders

    Drop empty layers or two anchor layers in your comp. Justae reads them.

  2. Step 02

    Write the intent

    Prompt per layer, references attached, length and seed if you need them.

  3. Step 03

    Batch generate

    One queue, one keystroke. Marker interpolations and Storyboard shots run together.

  4. Step 04

    Iterate in AE

    Retry, swap, re-time. Versions are kept. Nothing leaves the project folder.

Where it runs

Works where you already do.

Justae lives inside your editor, not a browser tab. After Effects today, and the DaVinci Resolve edition the community kept asking for is landing this week.

After Effects

The models

The model is a setting. The workflow is the product.

Models come and go. Your timeline, your version history, and your asset pipeline stay. Justae keeps the production system constant and swaps the engine underneath. Shipping today with Seedance 2.0 and HappyHorse 1.0, open to what comes next.

For AI labs: motion designers are a high-signal distribution channel. Talk to us about integration. We ship to the surface they already trust.
