3. Select a pattern from the Test Patterns drop-down list. A preview of the test pattern
appears above the drop-down list. Available test patterns include the following:
Color Bars Time Stamp Pulse Crop
Aspect Ratio 1.33:1 Aspect Ratio 1.78:1 Aspect Ratio 1.85:1 Universal OSD
Figure 51. Test Patterns
• The Pulse "test pattern" is an audio-only test. Select Pulse to output an audio pulse
of 400 Hz at -10 dBu for audio output testing.
• The Time Stamp pattern displays white text in a small, gray rectangle with the unit date
and time (for example: Fri Apr 18 HH:MM:SS) on a black background in the top left
corner of the display window.
• The Universal OSD pattern consists of a small, translucent, gray rectangle with white
text overlaid atop the source video content. It appears in the upper left of the screen.
The text includes brief custom text followed by three selectable elements separated by
commas. The options for those elements are listed in the Setting up the universal OSD
test pattern section below. The universal OSD pattern can be displayed together with
the main AV content because it overlays the video rather than replacing it. As a result,
the universal OSD pattern can be used at any time, not just during setup. It can also
serve as an onscreen label for presentations, in addition to metadata labels (which may
or may not be displayed, depending on the screen layout). See Encoder Settings and
Layout Presets Overview on page 90 for more information on metadata within
screen layouts and on selecting content for the metadata fields.
The selected test pattern is immediately output to the display and reflected in the preview
in the AV Controls panel on the left of the screen. The test pattern displays until another
pattern is selected, or until Off is selected from the Test Pattern drop-down list, or until
unit power is recycled.
NOTE: When a test pattern is selected, the test pattern is streamed to the display,
stream, and recording, overlaid atop the source AV material. If Off is selected from the
Test Pattern drop-down list, the test pattern is turned off.
Setting up the universal OSD test pattern
The universal OSD is a gray rectangle with white text that overlays the selected source video
as part of a "test pattern." It can be turned on or off as needed.
To set up the universal OSD test pattern:
1. Open the Input/Output Settings page.
2. Expand the OSD Configuration panel at the bottom of the page.
3. Select Universal OSD from the Test Patterns drop-down list.
4. Enter the text (up to 16 characters) into the Display Text field within the universal
OSD area in the Preview Output Configuration panel. This is the first text that
appears in the universal OSD, and can function as a brief title or description.
