Mitto Family of Scan Converters User Guide
Position and Size are used to select the portion of the computer screen to be scan converted and
output to either standard definition or high definition video. Position determines the upper left
corner of the region you are going to output, while Size determines the lower right corner of the
region for output.
Note: If the Selection Tool is in full screen mode (indicated by your entire desktop showing on the
output), size your box first and then adjust the position.
• Position – When the Position LED is blinking you can adjust the position of the upper left
corner of the selection. Use the four arrows to control position. Press and hold for faster
movement.
Short cut: Press and hold left and right arrows at the same time to reset the H position to
default values. Press and hold up and down arrows to reset V position to default values.
• Size – Determines the lower right corner of the region for output.
When the Size LED is blinking, adjust the position of the lower right corner of the selection.
Use the four arrows to control size.
Maximum Screen Selection Shortcut
To maximize the screen selection instantly, hold down the Up, Left, and Right Arrow buttons
simultaneously while Position or Size are active. Maintaining the currently selected aspect
ratio, Mitto will instantly maximize the screen selection on the computer monitor.
• Aspect – Lets you set a fixed aspect ratio of the portion of the screen you are selecting.
16:9 aspect ratio is appropriate for high definition. 4:3 aspect ratio is appropriate for
standard definition. With Manual selected, you can choose any arbitrary aspect ratio. Pillar
boxes or letter boxes are added automatically so that the output matches the output
standard selected.
• Border – This control lets you adjust a black border around the selected video as it appears on
the high definition or standard definition video output.
• Sharp – The Sharpness control ranges from a minimum value of 1 up to a maximum value of 8.
This is a set of variable filters used to configure the processing through which Mitto is moving
the input video to the output. The mid-range setting of 4 is recommended as a good place
to start. If you would like to sharpen your output, increase the setting from 4. If your original
content is too sharp, for example shows ringing, decrease the sharpness setting from 4.
• Bars – This control can be on or off. Off is the correct selection for normal video operation.
When turned on, color bars and a 1 KHz tone are output on the SDI outputs. This function is
generally used during the installation or setup process to confirm cabling downstream.
• Pwr (Power) – The power indicator illuminates green when the BrightEye unit has power and
the internal voltage regulator is functioning correctly.
