■ PALETTE EFFECTS

Position

The Position group of parameters allows you to position the image from top to bottom

and left and right in the screen. The parameter values vary from -999 to 999, where a

0 value is center screen. The horizontal position (X axis) is called H Pos. The vertical

position (Y axis) is called V Pos. For horizontal positioning, negative values of H Pos

move the image to the left of center. Positive values of H Pos move the image to the

right of center. For vertical positioning, negative values of V Pos move the image up

from center screen. Positive values of V Pos move the image down from center screen.

Crop

The Crop parameter is useful for removing unwanted elements from a picture such as a

boom microphone or other nuisances. The Crop parameter can be of great assistance

when substandard images are used. For example, when VHS or U-Matic tapes are cap-

tured, there sometimes are muddled elements in the bottom of the picture (some people

refer to this as flagging, but it is actually the point in the picture where head switching

occurs between the two video heads that scan the tape). In some cases, the vertical

blanking might show at the top of an image when it is scaled down for an effect. In

cases like these, the Crop parameter is a necessity.

Note: In addition to using the parameter sliders,Position and Scale parameters can be directly adjusted

by clicking and dragging the image in the monitor.Scale handles are indicated by white dots on the top and

side of the image.To position the image,click in the middle and drag it to the desired location.

Note: You can override the Fixed Aspect scaling button by directly adjusting the handles in the Record

monitor in Effects mode.You can also scale the image in increments of 25 percent by holding down the Shift

key when directly making adjustments via the handles in the Record monitor.If you want to return to the nor-

mal aspect ratio, click the Fixed Aspect button twice or grab the upper-right handle in the Record monitor.The

normal aspect ratio will return.
