# Lens Flare

> Drop a procedural lens flare — glow, streaks, and ghost blobs — anywhere in frame, aimed at a bright light source.

## What this node does

This node composites a synthetic lens flare over a `COMFYTV_VIDEO` clip: a central glow at a chosen position, optional horizontal anamorphic streak, and a chain of "ghost" reflections marching across the frame. It runs on a Torch backend as an fx-spec pass and passes the clip through untouched when `intensity` is 0.

It has a ▶ Run. Input and output are both `COMFYTV_VIDEO`. To hand the result to native ComfyUI nodes, insert a **Bridge** — see the [bridge note](https://github.com/jtydhr88/ComfyTV/blob/main/docs/bridges.md).

## When to use it

* Add a flare pointing back at the sun/practical light for a cinematic or sci-fi feel.
* Sell a hero shot or lens-driven transition.
* Fake a light source reaction the original footage lacked.

## Parameters

### pos\_x / pos\_y

Where the flare's bright source sits, each 0.0 to 1.0 across the frame (default `pos_x` 0.75, `pos_y` 0.25 — upper-right). The ghost chain runs from this point through the frame center.

### intensity

Overall brightness of the flare, 0.0 to 3.0 (default 0.8). 0 disables the effect entirely.

### size

Size of the central glow, 0.05 to 1.0 (default 0.25) as a fraction of the frame.

### streak

Strength of the horizontal anamorphic streak through the flare center, 0.0 to 1.0 (default 0.5). Turn to 0 for a round flare with no streak.

### ghosts

Number of secondary ghost reflections along the flare axis, integer 0 to 8 (default 5). More ghosts = a busier lens-reflection chain; 0 gives just the glow and streak.

## Outputs

| Output    | Type            | Meaning                                   |
| --------- | --------------- | ----------------------------------------- |
| **video** | `COMFYTV_VIDEO` | The clip with the flare composited on top |

## Tips

* Place `pos_x/pos_y` right on the brightest light in the shot so the flare reads as motivated.
* Lower `streak` and `ghosts` for a subtle glow; raise both for a stylized, obvious flare.
* Keep `intensity` moderate over bright backgrounds so the flare doesn't blow out the whole frame.
