Waveform Monitoring

Blackmagic UltraScope Displays

Blackmagic UltraScope software is a great tool for maintaining accurate broadcast legal video and audio

levels from your Teranex's converted output. Scopes used to monitor your levels include RGB Parade,

Waveform, Vectorscope, Histogram and Audio Metering Display.

RGB Parade Display

RGB parade displays the red, green and blue channels of your converted output. If one of the color

channels appears taller, it usually indicates the presence of a color cast. This may not be desirable and

you may want to try minimizing the color cast during post production using color correction software,

such as Blackmagic DaVinci Resolve.

Waveform Display

The waveform is great for seeing your black and white levels and overall image contrast. An image with

good contrast will display information from 0 IRE to 100 IRE. An image with poor contrast will have the

majority of information centered in the display, with little information in the top or bottom areas.

If you are seeing "milky" or gray blacks on your video display, then they will appear elevated above the

0 IRE line. To adjust the black level, press the BLK button on the front of the Teranex and use the rotary

knob to lower the black level. If you lower the black level below 0 IRE you will "crush" the image and

you risk eliminating shadow detail. Adjust the black level and observe the change on both the monitor

and the waveform.

Likewise, if your highlights appear muted or dull, they will appear below the 100 IRE line. To adjust the

white level, press the GAIN button on the front of the Teranex and use the rotary knob to increase the

white level. If you raise the level above 100 IRE you will "clip" the image and you risk eliminating highlight

detail. Adjust the white level and observe the change on both the monitor and the waveform.
