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

You can fine-tune the look with the effect properties: the line width and line contrast control the scanlines, curvature bends the image like a rounded screen, noise adds static, and vignetting darkens the edges. The scanlines can be animated (moving interlaced lines) by setting an Interlaced Lines Speed greater than 0.
Note
This is a 2D effect. It has no effect on 3D objects or 3D layers.
