CRT effect

Applies a CRT effect, simulating an old cathode-ray tube television.

Parameters

The effect combines several artifacts that you can tune independently:

• Scan lines: Line width and Line contrast control the horizontal scan lines. Enable Show vertical lines to draw them vertically instead.
• Noise: Noise sets the amount of static, and Noise size how coarse it is.
• Curvature: bends the image outward to mimic a curved screen. Set it to 0 for a flat picture.
• Vignetting: darkens the edges of the screen. Use Vignetting alpha and Vignetting blur to soften the darkened border.

The animation is driven by two properties: Interlaced Lines Speed (how fast the scan lines move, 0 to freeze them) and Noise Frequency (how many times per second the static is refreshed).
