Waveform Display - Blackmagicdesign ATEM Production Studio 4K Installation And Operation Manual

To check levels, simply press the YUV or YUV+ button.
The COLOR setting switches the RGB display to color rather than traditional black and white.
When the COLOR setting is used with the YUV or YUV+ display, luma (brightness) remains
white, B-Y (difference between blue and luma) appears blue and R-Y (difference between red
and luma) appears red. The COLOR setting is not a professional setting and should usually be
switched off, especially when showing video to clients.

Waveform Display

The Waveform Display is similar to traditional composite waveform monitors seen in many
broadcast studios. On Windows, select B/W for the luminance only view, COMP for the
composite only view, and BOTH for the twin luminance and composite view.
Select B/W for the luminance view which provides a digitally encoded waveform similar to
traditional luminance waveform monitors. The luminance view is very useful when adjusting
luma (brightness) levels in an image. Turn on the GAMUT function, and any illegal luma levels
will be highlighted in bright red, so they are easy to see. Instructions for setting luma limits can
be found in the Error Logging Display section of this manual. Traditional luminance waveform
monitors only supported composite analog standard definition video. However UltraScope's
luminance view works in high definition as well as standard definition, so you have a consistent
and easy way to adjust luma levels even when monitoring high definition digital video formats!
For Windows users, the composite view is exciting because it's a fully digitally encoded
composite waveform view and similar to a traditional waveform monitor. This provides a much
easier way to align to test signals, such as color bars, because you can use the composite
waveform exactly the same way as it has always been used. Composite view also works in high
definition, so you have a consistent and traditional way to adjust video even when working in
high definition!
Waveform Display on Windows can show,
Luminance Composite or Both views
When BOTH view is selected on a Windows PC, the composite and luminance waveforms
display side by side in a twin view. This is incredibly useful when adjusting video levels or color
correcting. It's impossible for a vectorscope to show which objects in the video have color
because a vectorscope just shows what colors are in the whole image and not which objects
have color. When color correcting, you often need to look for specific parts of the image,
remove the color and produce a neutral state. This is because the composite waveform is the
same as the luminance signal but with chroma added.
