Adjusting The Sync And Subcarrier Phases - Sony 85P Operating Instructions Manual

Adjusting the Sync and Subcarrier Phases

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.
