Transform Context node

The Transform Context node defines an output canvas — a fixed working resolution that elements are positioned and scaled within. It's how you build a composed shot: a background, a camera in one corner, a logo in another, a lower third along the bottom — all on one canvas.

Think of it as the "stage": each element you plug in gets an X/Y position and a width/height relative to this canvas, so the layout holds together no matter the projector resolution.

Add it: right‑click the empty canvas → Add Transform Context Node.

Wiring elements into it​

The node has a single gold Context Hub port. Drag from an element's Transform Context port to this hub to place that element on the canvas. The hub accepts many elements at once — connect as many as you want to compose them together.

Once connected, position each element either with:

  • the inline Transform ▸ controls on the element's card (X / Y / W / H as percentages), or
  • the visual transform editor (below).

The node's two buttons​

The node shows the canvas size (e.g. Canvas 1280×720) and has two click targets:

Edit button — set the canvas size​

Clicking the on‑node Edit button opens the visual Transform Editor, where you drag and resize the connected elements directly on a representation of the canvas — a hands‑on way to lay out the composition.

Double‑click / "Edit Canvas Size" — change the resolution​

Double‑clicking the node (or right‑click → Edit Canvas Size) opens the Canvas Size dialog:

  • Width and Height spin boxes for an exact resolution.
  • A Preset dropdown — Custom, 16:9 (1280×720), 16:9 (1920×1080), or 4:3 (1024×768) — which fills in the size for you.

The size you set becomes the coordinate space every connected element is laid out in.

Typical setup​

  1. Add a Canvas element (transparent or a colour) as your background.
  2. Add a Transform Context node and set it to your output resolution.
  3. Wire the background, a camera, and a text or HTML overlay into the node's hub.
  4. Position each with the inline Transform controls or the visual editor.
  5. Fire the composition to a deck and crossfade as usual.
