For a game I’m working on I was tasked with creating a camcorder/VHS and scanline distortion effect, which you can watch below! View in fullscreen for the best experience.

The scanlines are created using a simple custom HLSL node that sets every even line of pixels to black and applies a chromatic abberation. Then a rolling VHS distortion is created with overlapping sine nodes and clamps applied to the X/U coordinates of the screen texture.
