# Composer

Compose elements exactly as needed, for maximum control and consistency.

The Composer is your layout engine. It lets you layer multiple elements — images, text overlays, logos, graphics — into a single composed visual, similar to basic design tools.

Common use cases include placing a logo on a generated image, adding text overlays to product shots, or assembling multiple generated elements into a final ad creative.

The Composer supports both image and video output. Configure layer positions, sizes, and ordering directly in the node's visual editor.

This unlocks workflows that were impossible before:

* **Localize 20 ads in 20 languages** without rebuilding layouts manually
* **A/B test 50 headline variations** without touching a design tool
* **Generate seasonal campaign assets on autopilot**

### Quickstart (2 minutes)

Think of it as having a design canvas directly inside your flow where you can arrange, layer, and finalize your creatives:

* Generate all elements through your flow
* Connect them as inputs for the Composer node
* Set up your rules and guardrails (layout, typography)
* Run the node, let the Composer do its job
* Download the finished creatives

### When to use the Composer

Use the Composer node when your flow generates multiple elements that need to be combined into a final asset:

* **Ad creative production** - Combine product shots, headlines, logos, and CTAs into finished ad formats
* **Asset localization** - Create the same creative in multiple languages without rebuilding layouts manually
* **Social media templates** - Assemble branded posts with consistent layouts across platforms
* **A/B test variations** - Generate dozens of ad variants by swapping elements without manual composition
* **Multi-element campaigns** - Bring together background images, product photos, text overlays, and branding

### Timelines

Use timelines in the Composer when your final asset is a video assembled from multiple timed elements:

* **Hook testing** - Keep the b-roll, captions, and sound, swap the hook layer to produce variants
* **Catalog videos** - One timeline structure runs across every product in your catalog
* **Localization** - Swap captions and voiceover per market, layout and pacing hold
* **UGC assembly** - Combine hook, b-roll, captions, and sound into one edit
