## What this node does

**Art FX** runs a GPU (torch) art-style filter over a whole `COMFYTV_VIDEO` clip and writes a new snapshot on **▶ Run**; the source clip is untouched. Pick one of four looks with **mode** — each look reads its own subset of the parameters below.

In and out are both `COMFYTV_VIDEO`. To feed native ComfyUI nodes, insert a **Bridge** — see the [bridge guide](https://github.com/jtydhr88/ComfyTV/blob/main/docs/bridges.md).

## When to use it

* Turn live-action into a flat, posterized **cartoon** with inked edges.
* Give a clip a hand-drawn **charcoal** or **emboss** treatment.
* Apply a print-style **halftone** dot screen for a comic or retro poster feel.

## Parameters

### mode

The look. Options: `cartoon`, `charcoal`, `emboss`, `halftone`. Default `cartoon`.

### threshold

Edge / line sensitivity, `0.01`–`1.0` (step `0.005`), default `0.12`. Lower catches finer, more numerous edges; higher keeps only strong contours. Used by the edge-driven looks (cartoon/charcoal).

### levels

Color posterization steps, `2`–`32`, default `8`. Fewer levels = flatter, more graphic banding (cartoon).

### diff\_space

Edge-detection spacing, `1`–`4`, default `1`. Larger values sample edges over a wider pixel gap for thicker/coarser lines.

### edge\_scale

Edge line strength / thickness multiplier, `0.1`–`8.0` (step `0.05`), default `1.5`. Raise for bolder outlines.

### scatter

Stroke scatter / jitter, `1`–`4`, default `1`. Higher adds a rougher, less uniform stroke (charcoal-style).

### color\_mix

How much of the original color bleeds back into the stylized result, `0.0`–`1.0`, default `0.0`. At `0` the look is fully stylized; raise toward `1` to blend the source color back in.

### invert

Flips the light/dark polarity of the line or emboss result. Default off.

### azimuth / elevation

Emboss light direction. **azimuth** `0`–`360°` (step `1`, default `135`) is the light angle around the frame; **elevation** `0`–`90°` (step `1`, default `30`) is its height. Used by the **emboss** look.

### emboss\_width

Emboss relief width in pixels, `1.0`–`40.0` (step `0.5`), default `10.0`. Wider = a deeper, more sculpted relief.

### dot\_radius

Halftone dot radius in pixels, `1.0`–`10.0` (step `0.5`), default `4.0`. Larger dots = coarser screen.

### angle\_c / angle\_m / angle\_y

Halftone screen angles per channel, each `0`–`360°` (step `1`). Defaults `15` (cyan), `45` (magenta), `0` (yellow). Offset them to avoid moiré and get a classic CMY rosette.

## Outputs

| Output    | Type            | Meaning                                     |
| --------- | --------------- | ------------------------------------------- |
| **video** | `COMFYTV_VIDEO` | The stylized clip as a new project snapshot |

## Tips

* Many parameters only matter for their own look: **emboss\_width**/**azimuth**/**elevation** are emboss-only; **dot\_radius**/**angle\_c/m/y** are halftone-only; **levels** is mainly cartoon. Changing them in the wrong mode does nothing.
* Nudge **color\_mix** up a little if a stylized clip feels too monochrome.
