One Click to Move Selection to an Outside Edge
Clicking one of the smaller directional Position arrow buttons (with the perpendicular line) causes
the Selection area to move immediately to the outside edge of the direction chosen with one click.
Similarly, clicking the smaller down or right Size arrow buttons causes the Size of the Selection area
to move to an outside edge. However, clicking the smaller left or up Size arrow buttons minimizes the
size of the Selection.
• Position Default Button – Clicking the Default button for Position immediately places the
position of the Selection area at the upper left corner.
• Size Default Button – Clicking the Default button for Size immediately maximizes the size of
the Selection area within any aspect ratio constraints, but does not change the Position of the
upper left corner of the Selection area.
• Full Screen – Clicking the Full Screen button instantly maximizes the size of the Selection area.
The Position will be moved to the upper left corner while the Size will be maximized within any
aspect ratio constraints. Full Screen means that your entire desktop is shown on the output.
• Center – Clicking the Center button instantly selects an area in the center of your desktop that
is 50% of the total width, and the height that corresponds with the selected aspect ratio. The
primary value of this control is to provide a fast and easy way to see the selection tool.
• Border – Lets you adjust a black border pixel width around the selected video as it appears on
the high definition or standard definition video output.
• Sharpness – 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.
Note: Computer monitors typically have a refresh rate of 75 Hz or better (even as high as
250 Hz). Video output is fixed at 60 Hz for NTSC and 50 Hz for PAL. The discrepancy of the
refresh rate between the computer monitor and the video output causes flicker. Mitto uses
proprietary anti-flickering hardware and software that works all the time, automatically,
providing a high quality output that’s as good or better resolution as the original content.
Note: Subpixelization is a method used on computer monitors to fool your eye into
thinking that there is more detail and higher resolution than there actually is. It also helps
make text on your monitor look more like it will in print. Basic subpixelization splits each
pixel into three rectangles: red, green and blue. Although the eye does not generally
perceive this color in the text on the computer monitor, it is there. Because Mitto is very
good at capturing fine detail that is in the content, you may notice what look like color
artifacts in text on your output. If you are having this issue, go into the settings for your
computer monitor and turn off subpixelization, which may also be referred to as font
smoothing. On a Mac go to System Preferences: Appearance or General, and disable the
font smoothing. On a PC go to Control Panel: Display Properties: Appearance: Effect, and
disable the font smoothing.
