3:2 Seq Detect
This menu item is applicable only for standard video (component, s-video, composite) video inputs. The default mode
is off. The 3:2 Sequence Detect feature should be turned on to process video derived from film source material, which
is usually recorded at 24 frames per second.
Video Bandwidth
This menu item is applicable only for S-Video and Composite video inputs. The default mode is Full. The Reduced
setting can be used to soften the image by reducing horizontal bandwidth.
Video Peaking
This menu item is applicable only for S-Video and Composite video inputs. The default mode is Minimal (MIN).
Increased Video Peaking can be obtained by selecting the Nominal (NOM), Increased (INC) or Maximum (MAX)
settings.
Input Audio/Video Setup Menu (Advanced Mode)
When the Advanced Menu Mode is selected the Input Setup Menu will appear as shown below. Menu items that
differ from the standard Input Setup Menu are shown in bold print.
Only experienced operators should use the Advanced Input Setup Menu. This menu allows the user to configure the
unit for 1:1 Pixel Sampling to provide the highest possible image quality. Please note that while 1:1 Pixel Sampling
provides optimal image quality when properly adjusted, improper adjustment is likely to produce an image
considerably inferior to what is obtained with the Standard Input Setup Menu.

1:1 Sampling Overview
In order to scale an image, it must first be digitized. This is the process of changing the analog video signals (Red,
Green, and Blue for example) into pixels stored in the system’s image memory. The default mode of the
PresentationPRO is to over-sampe the input image producing more samples than there are in the original source
material. The over-sampled image is then scaled to the final output resolution.
The approach called “1:1 Sampling” produces a superior image by sampling the analog graphics signals at exactly
the same rate as that of the original source. This allows the image to be re-constructed with reduced digitizing
artifacts. The 1:1 Sampling approach requires very accurate sample clock frequency and phase settings. Even small
