36Basic OperationFor luminance keying, chroma keying orexternal keying, apply effects such as slice andslope to the key video ( page Vol.2-6).5 Set the pattern position (where the key isinserted) using the joystick.Press the CENTER button to turn on, and the patternposition is set to the center.Press the HOLD button to turn on, and the joystick isfixed to the current position. NOTEThere are some patterns for which the position•cannot be adjusted with the joystick. For more information, refer to “List of KeyPatterns” at the back of Volume 2.For the patterns registered as direct patterns, the•settings of the effects and position applied to eachpattern are saved in memory and applied when thepattern is called next time (if [MODE] in the [SETUP]menu is set to [PRESET]). Any settings made for thepatterns not registered as direct patterns are notsaved in memory.6 Set the pattern size (key size) using the rotaryZ control.If a specific key pattern is selected. press theASPECT button to turn on, and the aspect ratioof the pattern can be temporarily changed withthe ASPECT control. (When it is turned in the Hdirection, the width (horizontal) is increased; whenit is turned in the V direction, the height (vertical) isincreased). When the button is turned off, the aspectratio returns to the value before change. For patterns to which the aspect change functioncan be applied, refer to “List of Key Patterns” at theback of Volume 2.7 Set the transition time (from combining start toend) ( page 35).8 Slide the transition lever to the B side (or Aside) or press the AUTO TAKE button.When the AUTO TAKE button is pressed, it is lightedand source video A is combined with B (or sourcevideo B is combined with A).To use the Scene Grabber functionPress the SCENE GRABBER button to turn on.The scene grabber function allows you to move the imagecurrently being displayed in the key together with thepattern if a specific key pattern is selected. For patterns to which the Scene Grabber function canbe applied, refer to “List of Key Patterns” at the back ofVolume 2. NOTEYou cannot use multi-strobe effects ( page Vol.2-15) andthe scene grabber function at the same time. Whichever isselected later has priority and the other selected earlier iscanceled.To display the key invertedPress the REVERSE button in the PATTERN area to turn on,and the key pattern or frame-in/-out is displayed inverted.Downstream Key (DSK)DSK is an effect of inserting a key to the video to whicheffects have already been applied.The following diagram shows an example of the DSK.To create DSK using material importedfrom PCInput material such as characters created with a singlecolor as a background on PC to the DVI-I IN connector,select the DVI-I input as key material for DSK (set [KEY] to[DVI-I] in the [DSK SOURCE] submenu of the [DSK FADE]menu), and you can insert a key onto video created byapplying effects to an image taken with a camera.It is also possible to embed other material as the key fill inthe key extracted from the original material or apply effectssuch as SHADOW to the extracted key.
