Calibrating for Video Output

1044

Before you calibrate video output for an NTSC-EIAJ project (for Japan), make sure the

“NTSC Has Setup” option is not selected in the General Settings dialog box, accessed from

the Settings list in the Project window. For more information on General settings, see

“General Settings” on page 1411.

You cannot set separate calibration levels for S-Video output, Composite output, and

Component output. When calibrating video output, select one video output for calibration.

The two other outputs are not guaranteed to be properly calibrated. If you need to send

output to more than one SD device, Avid recommends that you use one analog output

(Composite, Component, or S-Video) and one digital output (SDI).

For HD projects, you can calibrate only HD component output, which is usually used for

monitors. You cannot calibrate output for HD-SDI.

Using the Factory Preset Buttons in the Video Output Tool

The preset buttons in the Video Output tool show the status of each Calibration setting as

follows:

• When the Video Output tool opens the first time you run your Avid editing application, all

preset buttons are lit (green), with the factory presets loaded for each slider.

• When you click a slider of a lit preset button, the button dims (appears gray), and the slider

returns to the most recent manual level setting.

• When you click an unlit preset button, it becomes lit (green), and the slider moves to the

factory preset level for that parameter.

• As you adjust levels in the tool, you can switch the preset buttons between the levels you set

manually and the factory preset levels. These adjustments are described in “Basic Video

Output Calibration” on page 1045 and “Calibrating the System with Passthrough Signals”

on page 1048.

Set Vertical Blanking Interval If this option is available for your input/output configuration, you can instruct

the system to preserve 5 lines above each field in NTSC and 8 lines above each

field for PAL. These lines can be used to store additional encoded information

such as closed captioning, edgecodes or keycodes for film projects, or various

interactive or enhanced TV codes. For more information, see “Vertical Blanking

Information” on page 1086.
