Adjusting Phase Controls
The Video Output tool provides controls for adjusting horizontal phase globally for output.
Horizontal phase, or H Phase, is the horizontal blanking interval used to synchronize the
timing of two or more video signals. SC Phase (subcarrier phase) controls are also available
for timing two or more signals based on the color burst portion of a composite or S-Video
signal. System Phase controls let you adjust the output signal relative to a reference signal.
In most situations, you do not need to calibrate the horizontal phase, subcarrier phase, or
system phase of the output signal. If you are working in a production house in which timing
is necessary between various devices—such as switchers, decks, and monitors—use these
controls to adjust phase globally for all outputs from your Avid editing application.
Preparing for Converting HD Formats
Your Avid editing application attached to an Avid Adrenaline, Avid Nitris DX, or Avid Mojo
DX can crossconvert an HD sequence to another HD format or downconvert an HD
sequence to an SD format, provided that the sequence has a compatible frame rate for the
format to which you are converting. Before you output a converted sequence, you need to set
the appropriate options in the Video Output tool.
For information and notes on available crossconversion and downconversion formats for
each HD format, see “Crossconversion and Downconversion Formats” on page 1001.
For a list of considerations when crossconverting or downconverting, see “Considerations
for Crossconversion and Downconversion” on page 1002.
