What is already available during start up ?
During the installation of a file with LOAD, the horizontal period, the total number of vertical lines and the interlaced mode are
automatically measured and filled in. These values will be available when starting up the EDIT procedure of an active file.
Adjustable items
•
Active horizontal pixels : determine the width of the window on the screen. This value is normally given in the source specifi-
cations. If not, adjust until full image is displayed (no missing pixels).
•
Horizontal start in pixels : number of pixels between the beginning of the input signal and the start of the video information in
the signal.
•
Horizontal period in ns : when active file, the correct value will be filled out.
•
Active vertical lines : number of horizontal lines determining the height of the projected image. this value is normally given in
the specification of the source. If not, adjust until full image height is displayed (no missing lines).

The Comb filter is by default enabled.
The AGC hold interval is the time interval in which the AGC is inhibited (AGC hold = no update in video amplitude measurement),
the advanced parameter allows to choose a short or long hold interval.
A long AGC hold interval eliminates Macrovision
probability to encounter a Macrovision
The sync locking setting is recommended for poor video signals (ex: poor TV signals).
Sharpness adjustment can be chosen to be coarse or fine.
It is recommended to use the default values.
