ZEN NDI® False Colour Monitor

USAGE NOTES

2) The default layout mode is a pair of identical video preview monitors, arranged horizontally, each of which has the option to display the image as “false colours”, for the purposes of exposure control (applied externally, e.g. on the camera source), or can be used as a Waveform Monitor. NDI® tally signals are supported and will be displayed as red or green borders on the video image.

3) Each monitor has the following controls beneath it.

a) The False Colour button on the left toggles the display mode, and is highlighted in mauve when active.

b) The LUT1/2 radio buttons select different false-colour look-up tables. At present there are two LUT tables included.

c) WFM (WaveForm Monitor). The button turns green when active and overrides the LUT options. The graticule lines can be set to either .3 – 1.0 (= volts, for people who grew up in the analogue video era) or 0 – 100%. Click on the numbers down the left side of the WFM display to toggle between them.

d) NDI® sources on the LAN are continuously detected and displayed in the list-box lower right. Clicking on a source in the list will connect to it. Viewing the dropdown list while a source is already connected will disconnect the active one, even if no further selection is made.

3) The system menu has some additional options, below the “About” item.

a) “Always on top”. Pretty much self-explanatory.

b) “Low Q, Lower CPU”. Selecting this item will reduce CPU usage at the expense of image quality (by “binning” pixels), although the level of quality reduction is very content-dependent. On some types of content there can be little visible difference, others much more so. Adjust to taste.

c) “Layout Modes”. Opens a dialog box showing three layout mode options, (a) 2 inputs, each with single displays, (b) 1 input with dual displays (horizontally), (c) 2 inputs, each with dual displays (vertically). The “quad” mode (c) opens a second row of display windows, so that each of the selected NDI® inputs is shown on both rows. However, the display mode of the lower windows is fixed, whereas the upper windows can be switched between normal, false-colour and waveform monitor modes. The lower row can act as a reference when observing the effect of false colour or viewing the waveform monitor above.
