Figure 4-14. The Processing Submenu
The options on this submenu are:
• DeIntlc — Converts interlaced video to progressive format for processing.
The ImagePRO-II utilizes an advanced Motion Adaptive De-interlacing (MAD)
mode to deinterlace most video sources up to HDTV (1920 x 1080i) rates.
An alternate mode, Field to Frame (Fld->Frm), avoids motion artifacts by
converting individual input fields to progressive output frames. While vertical
resolution is reduced in this mode, video processing delay is also significantly
reduced.
The following table shows the maximum delay for each mode, for both interlaced
and progressive video.
• Motion Thresh — If DeIntlc is selected, Motion Thresh adjusts the threshold of
the motion adaptive de-interlacer. Because adjustment is rarely required, it is
recommended that you leave the function at its default setting.
• Pulldown Compensation — This function, which detects the 3:2 film pulldown
sequence, can be either On, Off, or not applicable (n/a). It should be turned On to
properly process video derived from film source material. The default setting is
Off. This function applies only to standard video (component, S-Video, composite
and SDI) inputs. For other inputs, the value is n/a.
