You've probably noticed switches 8 and 7 share settings for up and down conversions. This is
because aspect ratio settings are determined by the output settings. For example, if you have
switches 3 and 2 set for 1080i50 HD output, and processing switch 1 set to ON, Mini Converter
UpDownCross will automatically set switches 8 and 7 for down conversion.
Below is a description for each aspect ratio conversion:
Up conversion
‚ 4:3 Pillarbox: This setting displays 4:3 standard definition inside a high definition 16:9
frame. Black bars feature on the sides.
‚ 14:9 Pillarbox: This setting is a compromise between 4:3 pillarbox and 16:9 zoom. The
standard definition 4:3 image is slightly zoomed into, allowing more image in the 16:9
frame and reducing the amount of black bars on the sides, but slightly losing the top
and bottom.
‚ 16:9 De-Squeeze: This setting de-squeezes the standard definition 4:3 anamorphic
image until it completely fills the 16:9 frame. None of the 4:3 image is lost.
Down conversion
‚ Letterbox: This setting scales the entire 16:9 HD image into a 4:3 SD frame without
squeezing, leaving black bars on the top and bottom.
‚ Anamorphic: This setting horizontally squeezes the 16:9 HD image into a 4:3 SD frame.
‚ Center Cut: This setting cuts a 4:3 SD frame from the 16:9 HD image. This aspect ratio
setting discards a portion from each side of the 16:9 image.
Switch 1 - Processing Off - Processing On
When switch 1 is set to OFF all conversions are bypassed and the Mini Converter can be used
to distribute your video to six SDI destinations.
