Polar Fringe is an analog chroma key generator with a continuously variable soft edge surrounding its location the colorspace. With wide bandwidth voltage control over all four parameters, it’s hard to draw the line hard line between chroma keyer, a complex 2D processor, or even a de-colorizer. Welcome to the fringe.
- Width, 16HP
- Mounting Depth, 36mm
- Power +12V @ 125mA
- Power -12V @ 130mA
- THE CHROMA KEY PATCH
Set all controls and switches to the default settings shown on
the frontpanel illustration to the left.
Patch your RGB image source into the source inputs. Patch the
RGB Thru outputs to your compositor module’s RGB inputs
(such as Visual Cortex or Marble Index.)
Next, patch one of the Key outputs to the voltage control input
on your compositor module (Visual Cortex or Marble Index.)
Now you can use the joystick, Diameter, and Fringe controls to
change the color and quality of the resulting key.
- Try thinking outside the box with how you include it in a patch – for example, feeding ramp signals or horizontal and vertical waveshapes into the RGB inputs will transform it into a capable shape and pattern generator!
