Adjusting the Sync and Subcarrier Phases
When using two or more players, as in an A/B roll
editing system, phase synchronization of the signals
(i.e. system sync) is necessary and for composite
signals, the subcarrier phase must also be in sync. If
not, picture instabilities or color break-up may occur at
edit points.
After configuring the editing system, use a vectorscope
to adjust the sync and subcarrier phase of the recorder
and players. Subcarrier phase adjustment is necessary
when using composite signals.
