5.26.1 Video Output Editor

The Video Output Editor defines the synchronization standard and the output signal

phases.

• Freerun: Locks Viz Engine to a clock signal on the video board.

• Blackburst and Tri-level: Locks Viz Engine to a GenLock signal.

• Digital Input 1 and 2: Locks Viz Engine to the signal on Input 1 or 2.

• H-Phase and V-Phase: Shifts the output signal with respect to the sync signal.

To make the V- and H-phase values coincide

1. Set the V-phase value

• The V-granularity is taken from the genlock

• The V-delay is calculated from V-phase * V-granularity

• The genlock is set with this V-delay

2. Set the H-phase value. Note that there is a distinction whether the H-phase is a

positive or a negative value.

1. If the H-phase > 0

• The genlock H-delay is set to 0

• The H-granularity is taken from the video out channel

• The H-delay is calculated from H-phase * H-granularity

• The fill and key channels are set with this H-delay

2. If the H-phase <=0

• The fill and key channel H-delay is set to 0

• The H-granularity is taken from the genlock

• The H-delay is calculated from - H-phase * H-granularity

• The genlock is set with this H-delay

Note: The granularity and possible min/max values are printed to the Viz console

during startup.

It should be taken into account that when the genlock video format is different from

the fill/key video format the value of the V-delay matches the genlock lines and not the

video output lines. The same applies to negative H-phase values.
