# Flam Node

> Generate alpha-channel motion clips you can composite over anything.

export const DemoVideo = ({src, poster, caption, aspectRatio = "16 / 10", className = ""}) => {
  return <figure className={`not-prose my-6 w-full ${className}`}>
      <div className="overflow-hidden rounded-2xl border border-gray-950/10 bg-gray-100 dark:border-white/10 dark:bg-white/5" style={{
    aspectRatio
  }}>
        <video src={src} poster={poster} loop autoPlay muted playsInline className="h-full w-full object-cover" />
      </div>
      {caption && <figcaption className="mt-2 text-center text-sm text-gray-500 dark:text-gray-400">
          {caption}
        </figcaption>}
    </figure>;
};

A Flam is a 5–10 second motion clip with transparency — Flowy's own media type for animated overlays. Generate one from text, images, or video references, then composite it over any other footage without a box around it.

## Generate a flam

Write a prompt describing the motion you want, optionally connect image or video references, and click **Run**.

| Setting      | Choices               |
| ------------ | --------------------- |
| Duration     | `5s`, `10s`           |
| Aspect ratio | `16:9`, `9:16`, `1:1` |
| Resolution   | `720p`, `1080p`, `4k` |
| Audio        | On or off             |

## Frames vs. reference inputs

Connected images and videos play one of two roles, set on the node:

* **Frames** — first/last conditioning: the clip starts on your first image, and optionally ends on the second. Maximum of 2 inputs. Use it to bring a specific still to life.
* **Reference** — style and subject references: up to 9 images and videos condition the look without pinning the start frame. Use it to keep a character or product consistent while the flam invents its own motion.

If you connect more than two inputs while in frames mode, the node asks you to switch to reference mode before it generates.

## Built for compositing

The point of a flam is the alpha. The clip is keyed against its background color, so when you drop it into a [Composition](/canvas/nodes/composition) or a [Studio](/studio/overview) timeline, it sits cleanly over your footage — animated characters, particles, lower-thirds, and effects layers all read as native parts of the shot. Fine-tune the matte with the chroma key controls in [Studio's effects](/studio/effects/chroma-key) if an edge needs work.

Flam outputs also connect onward into **Video** and **Storyboard** nodes as references, so a flam you like can seed the next generation.
