FRAME RATES AND PULLDOWNS EXPLAINED
2:3:3:2 (advanced) pulldown
This method is very similar to the normal pulldown. Unlike the normal pulldown method, the resulting 30 fps video sequence contains only one 
frame containing fields from two different source frames.
The advantage of this method is that it is easier to reverse, if necessa\
ry.

How to use the lens charts
The lens charts on the following pages provide a quick guide to the 
type of lens needed for a particular projector.
To use the lens charts, you need the following information:
• The distance between the projector and the screen (throw 
distance)
• The maximum width of your screen
In the chart, find the point where the throw distance corresponds to 
the screen width, as shown in the example below....
