Introduction to DVD Automatic Aspect Ratio Adjustments
When enabled, Zoom Player can react to different DVD Aspect Ratio modes (as specified on the DVD Disc)
by changing various aspects of the player (image position, image blanking, aspect ratio, etc).
There are three types of DVD video content:
4:3 Full Frame
Full Frame Video that fits the entire screen area on a non-widescreen 4:3 TV Set.
16:9 Letterbox
Widescreen Video with the black bars at the top and bottom fully encoded into the video.
16:9 Anamorphic
Widescreen Video with 33% extra vertical resolution with part of the black bars being recreated
in software to compensate for the improved vertical resolution. This provides better image quality
compared to Letterbox.
Zoom Player can detect these DVD types and automatically set a Video Position/Size Preset, Blanking Preset,
Aspect Ratio Preset and execute an external program for each time an aspect ratio change is detected (one DVD disc
can contain multiple content types). This is useful for automation on 16:9 Anamorphic displays and other custom conditions.
Zoom Player also allows you to set default values when the disc is initially played.
