How finding the correct values for the displayed item?
During the installation of a file with LOAD, the horizontal period, the
total number of vertical lines and the interlaced mode are automati-
cally measured and filled in in the menu table. These values will be
available when starting up the EDIT procedure of an active file.
If the value for
"Horizontal total pixels"
is wrong, sampling mistakes
(small vertical bars in the projected image) will be seen in the image.
Select "Total" and adjust the pixel quantity. Adjust for zero bars (hint:
if the number of bars increase, adjust in the other way).
The
"active pixels"
: determine the width of the window on the screen.
This value is normally given in the source specifications. If not, adjust
until full image is displayed (no missing pixels).
"Horizontal start
" : number of pixels between the beginning of the
input signal and the start of the video information in the signal.
"Horizontal period"
: already filled in with the correct value when active
file.
The
"Vertical Total lines"
are already filled when an active file is
selected to be edited.
The
"Active lines"
: number of horizontal lines determining the height
of the projected image. This value is normally given in the specifica-
tion of the source. If not, adjust until full image height is displayed (no
missing lines)
Vertical start
: number of lines between the start of the input signal and
start of the image on the screen.
Interlaced [On] or [Off]
: this selection is automatically filled when
active file has to be edited. If the image is wrong due to
Select with or
