OmniTek OmniTek XR manual Window Controls, Snap

The display of the mini-pic defaults to normal, full colour mode. When using the XR in a colorist environment, where brightly coloured displays can be a distraction for the colorist, it may be helpful to switch the mini-pic into the monochrome mode.

The mini-pic can also be switched into a blue or green mode, whereby the blue (or green) data is applied to all three channels. This can be very helpful in looking for noise, or perhaps for looking for macroblocks, which tend to be more pronounced in the chroma channels over the luma channels, especially in HD.

Show Closed captions is only useful if the incoming material (or test sequence) contains closed caption source, and if the correct source has been selected, which is also done from the Analyzer menu of the main application.

The aspect ratio of the mini-pic can be changed from its default settings to preset values, or to a custom value, or may be forced to follow the Wide Screen Signaling values that can be contained within PAL video.

The display of the crosshair on the mini-pic window can be enabled or disabled.

Active tooltips shows the mouse position in pixel sample number, and video line. For interlaced video formats, the line number will be displayed based on the field selection that has been made on the Crosshair toolbar, as described on page 33.

The Look & Feel brings up the common Look and Feel dialogue, directly onto the mini-pic settings page. You can select the colour of the crosshair, and independently the colour of the cursor.

Lastly, you can save a snapshot of the currently displayed image. This is saved as a

.BMP file.

Window Controls

The waveform window, the vectorscope window, the data view window, the audio meters window, and the mini-pic window all have drop down menus to configure how the window contents are displayed, or the window manipulated. Not all windows have exactly the same controls, but the following section should cover all of the available features.

The windows all have an ‘Option’ menu. Depending on window, this will have the following selections.

Data	Change from RGB to GBR format.
Graticule	Enable the display of graticule
	Show graticule labels
	Specify graticule as SMPTE range, or full range.
	Choose graticule as 75% or 100%, for vectorscope
	Choose calibration for different PPM scales, for audio levels
Crosshair	Show crosshair
Aspect ratio	Choose aspect ratio for mini-pic as one of a selection of standards, or
	choose custom aspect ratio
Show Tooltips	Gives line and sample number of point under cursor.

The windows also all have a ‘Window’ menu. This provides the following possibilities.

Full Screen	Select this and the chosen window data will be displayed in a full screen
	mode, without any windows artefacts present, such as toolbars, menus
	etc. Press Escape to return to the standard display.
Resize	Select this to change the window size to the default minimum size to suit
	the data being displayed.
Snap	If this choice is enabled, windows snap to points on a grid as you move
	them around, which sometimes makes it easier to line them up as you
	require.
Stretch	By default as windows are resized, the data remains the same, with the
	extra space padded with black. By selecting this option, the data
	contents are stretched to full the window, although still maintaining the
	original aspect ratio.
