2:2 Pulldown detection (PAL film mode detect) submenu
For the currently selected input, set this feature to “On” if the source is PAL video
that originated in film. For standard PAL video sources, such as cameras, set this
feature to “Off” (default).
This feature does not apply to NTSC video sources since film
mode (3:2 pulldown) is automatically detected for those signals.
From this submenu, use either the horizontal Adjust ( ) knob or vertical
Adjust ( ) knob to specify this mode as “On” or “Off”.

Optimizing the System for a DVD Player
For optimal performance, follow the steps in this section in order when setting
up the IN1502 for a DVD player.
Setting up a DVD source
To get the best results when using a DVD as a video source, Extron recommends
that the DVD player itself be set up to output an aspect ratio of 16:9 and not 4:3.
Because all DVDs are mastered as 16:9, having them set up for anything else will
cause the player to internally scale and compress the signal. This scaling/
compression by the DVD player will defeat the advantage of having 3:2
pulldown detection in the IN1502.
All sizing adjustments to correct aspect ratio should be done using the IN1502.
To change the output aspect ratio of most DVD players,
1. Enter the DVD player’s Setup or Action menu while the disc is stopped.
2. Select a 16:9 aspect ratio.
