Video Output
•
Pass Through (Cap) - This selection directs Avid Artist | DNxIV to route video from its selected
input through the card for processing and output.
•
Test Pattern - This selection directs Avid Artist | DNxIV to output a preset pattern when no other
application is in control. The pattern is selected from the Test Pattern dropdown list below, or a
graphic file can be chosen.
•
Hold Last App - This selection directs Avid Artist | DNxIV to hold and output the last frame of
video from the last application to control Avid Artist | DNxIV. This can be helpful when
operating in an environment where you’re switching back and forth between multiple application
windows.
Test Pattern
With Test Pattern selected above, you can choose the pattern type. Select from:
•
Black, Color bars (75% or 100%), Ramp, Multiburst, Line Sweep, Multi Pattern, or Flat Field,
Check Field, White, Border, Linear Ramp, Slant Ramp, Zone Plate, Color Quadrant, or Color
Quad Border.
For HD and UltraHD with RGB-12 Pixel Formats the following HDR test patterns are available:
•
HDR Zone Plate, HDR Linear Ramp, HDR HLG Narrow, HDR PQ Narrow, or HDR PQ Wide.
Graphic File Display
In addition to the test patterns above, a “Load File...” selection at the bottom of the Test Pattern
dropdown menu allows you to load a standard RGB/RGBA graphics file (.tif,.psd, etc.) into the frame
buffer for display (including alpha channel). Some graphics formats and bit depths may not be
supported. Files that have been loaded are listed for quick reuse. Loaded graphic files are retained for
redisplay if another test pattern is selected, and even if Avid Artist | DNxIV is power cycled.
n
A loaded graphics file will not be scaled to fit. If it's smaller than the current frame buffer format,Avid
Artist | DNxIV will center it in the frame. If larger than the current frame buffer format it will be
cropped.
•
Clear Files - This selection on the pulldown clears all the Graphic Display files.
Fan Settings
Avid Artist | DNxIV offers a fan speed control. The High setting forces maximum fan cooling, with
some increased noise, but this setting could be appropriate if the unit is located in, for example, a
machine room rather than an editing suite.
•
Auto - Fan speed controlled by temperature, increasing or decreasing automatically.
•
High - Fan always operates at its highest speed.
Playback Timing
Use these controls to set the Genlock source and Timing adjustment.
