Chapter 6 Monitoring 113

Monitoring Broadcast Video Output

For the most accurate monitoring of broadcast programs, Color ouputs standard and

high definition video using supported third-party video interfaces. The drivers installed

for the interface you have determine what resolutions, bit depths, and frame rates are

available for outputting to an external monitor.

To turn on external video monitoring:

m Choose an option from the Video Output pop-up menu, in the User Prefs tab of the

Setup room.

To turn off external video monitoring:

m Choose Disabled from the Video Output pop-up menu.

Mixing and Matching Program and Viewing Resolutions

Ideally, you should monitor your program at its native resolution (in other words, the

resolution of its source media). However, Color will do its best to output the video at

whatever resolution is set in the Video Output pop-up menu of the User Prefs tab. If the

Video Output pop-up menu is set to a different resolution than the currently selected

Resolution Preset, then Color will automatically scale the image up or down as

necessary to fit the image to the display size.

Bit Depth and Monitoring

The working bit depth can have a significant impact on the quality of your monitored

image. The monitored bit depth depends on three factors:

Â The bit depth of the source media

Â The bit depth selected in the Video Output pop-up menu

Â The bit depth selected in the Internal Pixel Format pop-up menu

Other then specifying or choosing the initial shooting or transfer format, the bit depth

of the source media on disk is predetermined (usually 8-bit, 10-bit, or 10-bit log). Since

low bit depths can be prone to banding and other artifacts during the color correction

process (especially when gradients are involved), it’s usually advantageous to process

the video at a higher bit depth than that of the original source media (secondary

corrections and vignettes can especially benefit).

Color will process and output your video at whatever bit depth you select. However,

most broadcast video interfaces max out at 10-bit resolution. For maximum quality

while monitoring, you should set the Internal Pixel Format to the highest bit depth you

want to work at, and make sure the Video Output pop-up is set to a 10-bit option.

Note: Video noise and film grain often minimize the types of artifacts caused by color-

correction operations at low bit depths, so the advantages of working at higher bit

depths are not always obvious to the naked eye.
