MVIP stands for "Mini Video Image Processor" which means it´s a module for processing video signals. It changes incoming images by five parameters, manually and with control voltages.
The module processes video signals by changing brightness, hue (color nuances) and by swapping bits and it has some additional modes, too. Those parameters can be controlled by potentiometers and with CVs from 0-5V. The MVIP works in "component format" so it divides the image in three different signals: brightness (Y), hue between yellow/green and blue (B-Y) and hue between cyan/green and red (R-Y). It digitizes the image into a 24Bit signal - each 8 bits for brightness (black/white), B-Y and R-Y.
- Brightness: controls the brightness of the signal. Neutral setting in 12h position. counterclockwise is darker, clockwise is brighter. Interesting effects occur when BitSwap is activated (see below).
- Hue 1 controls B-Y: Neutral setting at 12h. left of this the signal gets more yellow/green, right of it more blue
- Hue 2 controls R-Y: Neutral setting at 12h. left of this the signal gets more cyan/green, right of it more red with a touch of magenta.
- BitSwap swaps the bits of course and thus the color information and grey scales in 32 different settings. This results in intense changes in color and brightness with strong edges but it also amplifies noise.
- Mode is the most complex parameter with 56 settings in 4 sub-parameters which are: positive image with four different bit settings (read: four color depths) ; negative image with four different bit settings, pixelization mode with 16 settings and luminance colorizing in 32 settings.
MVIP scans the CV inputs with 90kHz; if you modulate with an oscillator frequency above 15kHz, diagonal stripes in the image are created. The module automatically detects if the input signal is NTSC or PAL. If PAL is input, PAL will be output. The MVIP can also create images without an input signal, for that reason there´s a jumper for this mode selecting if the module outputs NTSC or PAL by itself.
- Composite Video input, Composite Video output (Cinch or "RCA" sockets)
- CV inputs for modulating brightness, hue 1, hue 2, BitSwap and mode
