Distorts the image so it appears to have been transmitted as an analog television signal.
Flagging— Skews the top of the image toward the right, and the bottom of the image toward the left, as though the video signal has time base errors.
Tearing— Skews each row of the image toward the right, based on the brightness: another form of time base error.
Edge Blanking— The width, in Vuo Coordinates, of the black bars to draw along the left and right sides of the image, simulating the horizontal blanking interval.
Bearding— The brightness threshold at which light parts of the image turn dark, simulating the way analog video recorders react to video signal overload.
Bearding Distance— How far left or right to move the bearded areas, simulating the horizontal scan delay between overload and reaction to overload.
Ghosting— The strength of horizontal echoes, simulating long analog wave reflections.
Ghosting Distance— How far left or right to move each echo.
Ringing— The strength of horizontal oscillations, simulating short analog wave reflections. The distance is always 1 pixel, and every other ring is inverted.
Noise Amount— How much random chrominance noise to add to the image. More noise is added in dark areas of the image.
Vertical Offset— How far the image is vertically shifted, simulating loss of vertical sync.
This node also applies some random variation to the above parameters, to produce an animated effect.
