Position - Control Button
The nine (9) position control buttons specify fixed anchor positions within
the specified area selection. The button positions are Upper Left, Upper
Center, Upper Right, Center Left, Center, Center Right, Lower Left, Lower
Center and Lower Right.
Note Only one position is active. Selecting another position changes the active
position to the new selection.
If the “Center” position is selected, display remains centered even when the
Source Crop or Stretch settings are modified. If a different position control
is selected, the position may also be modified with X and Y percentage
values based on clip width and height.
Stretch
Stretch controls allow for quick adjustment of aspect ratio.
Preserve Frame Aspect
If this option is selected, when one dimension is changed, the other is
automatically adjusted to preserve the current aspect ratio. If this
option is not selected, both dimensions may be changed independently.
Ignore Pixel Aspect
If this option is selected, pixel magnification mapping is allowed
without regard for the native pixel aspect ratio.
Fit Full Image
Clicking this button sets the maximum image size so that the full image
fill both the width and height of the screen. Shortcut key: [
