Io HD Installation and Operation Manual — Using The AJA Control Panel
Down (Conversion) —for downconversion the following choices are available:
Anamorphic: full-screen “stretched” image
Letterbox: image is reduced with black top and bottom added to image area with
the aspect ratio preserved
Crop: image is cropped to fit new screen size
Up (Conversion) —the Up and Down pull-down menus are available when
conversion has been selected for the video path to/from the framebuffer and like
Hz formats are selected (the one exception is 1080PsF 23.98 which can be
downconverted to 525i 29.97.) Different choices will be available depending on
the type of conversion and formats being converted. SD to SD conversions are
essentially aspect ratio conversions to accommodate transforming anamorphic
images to letterbox or vice versa.
Note: The AJA Io HD is not a standards conversion device for conversions such as
NTSC to PAL or vice versa.
For Upconversion the following choices are available:
Anamorphic: full-screen “stretched” image
Pillar box 4:3: results in a 4:3 image in center of screen with black sidebars
Zoom 14:9: results in a 4:3 image zoomed slightly to fill a 14:9 image
with black sidebars
Zoom Letterbox: results in image zoomed to fill full screen
Zoom Wide: results in a combination of zoom and horizontal stretch to fill
a 16:9 screen; this setting can introduce a small aspect ratio change
SD to SD— this pulldown is for SD to SD aspect ratio conversion.
Letterbox: this transforms SD anamorphic material to a letterboxed image.
H Crop: will produce a horizontally stretched effect on the image; transforms
anamorphic SD to full frame SD
Pillarbox: will produce an image in the center of the screen with black borders on
the left and right sides and an anamorphized image in the center
V Crop: will transform SD letterbox material to an anamorphic image
