Neon Effects in Fusion: Lines, Glow and Object Outlines

1. Prepare the shot and the node graph

On the Edit page, isolate the section you need and create a Fusion Clip when appropriate. In Fusion, identify MediaIn and MediaOut before adding anything. A readable graph is much easier to revise later.

2. Create the neon line with Paint or a mask

Paint is convenient for drawn lines. Create a Stroke, set width and color, then animate Write On so the line reveals along its path. For geometric outlines, a Polygon/Polyline mask can be cleaner than Paint.

1. 1Add Paint.
2. 2Create a Stroke and set Brush Size.
3. 3Choose the core color.
4. 4Animate Write On or the mask length.

3. Glow: preserve the core and build soft bloom

One oversized Glow often turns a sharp neon line into a blurry blob. Keep a bright narrow core and make the outer bloom softer and wider. Two Glow passes with different settings can be easier to control than one extreme node.

4. Outline a person or object

For chroma-key footage, a matte can come from Delta Keyer. For normal footage, use an appropriate mask, track or segmentation method. Once you have a matte, derive an edge, color it and feed it into Glow.

5. Merge the layers cleanly

Composite source, line and glow so each element can be disabled independently. That makes intensity and color changes fast without rebuilding the graph.

6. Animate and review at playback speed

Offset multiple reveals, add easing and judge the result in motion. A neon effect can look great on a paused frame and feel far too aggressive during playback.
