The following video effects require a blue
chromakey background to the camera model. Also the
chromakey levels must be set correctly. See the Chromakey
Setup Suggestions at the start of this Section.
1 4)
Select PRESET 55. Note that chroma key is required. As the
colour wipes down the screen, move the HUE, SA TURA TION and
VALUE sliders for colour bands. This PRESET displays a live
analog image in front of still background. Move the ZOOM a nd
STRETCH controls to change background, leaving live image
unaffected. Press COLOURIZE bu tton and move HUE,
SATURATION and VALUE sliders for arresting colour changes.
Press INVERT STENCIL for the "invisible man" effect.

Select PRESET 58. Initially, there is just live image. Press
the FREEZE button. Now a frozen image appears behind live
image. This utilizes

CONTROL. Preset 59 takes this further by continually freezing
behind the live image, resulting in a trailing effect. PRESET 60
continually freezes at a rate set by RATE
2
slider.

Select PRESET 61. This carries on from PRESET 60 and
uses
Slide

- SCREEN CONTROL.
Slide
allows
continuous panning of the continually frozen image, so that the
image 'wraps around' the screen. HORIZONTAL and VERTICAL
PAN sliders work differently when
Slide is on. Rather than just
pan, they control the
rate 0/ change
of pan. Mid-position of these
sliders has a small dead-spot to help stop the image moving.
Panning can be very slow, or fast enough to give the impression
of stopping, much like the wagon w heels in old cowboy films.
Try moving the ZOOM slider for a big effect. PRESETS
62
and
63 selected in succession take this slide/pan/zoom combination to
new levels.

Select PRESET 74 for a good ghostly illusion. RATE 2 slider
determines the rate of
Strobe,

FREEZE CONTROL. The ghost image is a result of having Ghost
selected i n Video Menu 0 - DISPLAY CONTROL for both the
Stencil on area and the Stencil off area, that is the whole screen.
Ghost gives a double-exposure between the live analog image and
the field store. Also, a Solarize colou rizing is selected in Video
