Adjusting The Sync And Subcarrier Phases - Sony DSR-1800A Operating Instructions Manual

Adjusting the Sync and Subcarrier Phases

When using two or more players, as in an A/B roll editing
system, it is necessary to synchronize the sync and
subcarrier (for composite signals) phases of the signals to
be edited. If they are not synchronized, picture instabilities
or color break-up may occur at edit points.
